The article discusses the advantages and disadvantages of installing an electrical panel box outside, focusing on its durability, accessibility, efficiency, and safety. It highlights the importance of choosing the best location for your panel, with indoor panels being safer to access and outdoor circuit breaker boxes being more efficient.
Powerwalls are small enough to fit anywhere, including indoors or outdoors, and are designed with weather resistance in mind. Most inspectors recommend garages or basement exteriors as the two best locations for these panels. Hebel cladding is a strong and versatile material that offers thermal-efficiency and a rendered appearance. They are highly effective insulators, helping reduce heating and cooling costs.
Safety is another important consideration when installing an electrical panel box. Exterior placement minimizes the risk of fire or electrical hazards within your home, making it easier to contain potential dangers outside the living space. Space considerations are also important, especially in older homes where there might not be sufficient space indoors for a breaker box. Power panel exterior can handle higher electrical loads, making it a better option for larger homes or commercial buildings.
In-wall installation is usually the better choice for those who don’t have to place the panel outside, as it allows for more control over the panel and benefits from the benefits of the panel. However, on-the-wall installation is recommended for easy updates and avoids tearing apart the wall to add or change branch circuits.
In most places in the US, it is acceptable to install the electrical breaker panel inside or outside, but the panel must be rated for outside use. An interior panel with an outside disconnect is preferable, as there is a way to kill power in case of a fire. Breaker panels have good weight and the backside needs to be flush-mounted.
In the US, breaker panels are most commonly located on an exterior wall, often closest to the access point of the power line feeding the property. If you plan to have the house resided in the future with new vinyl, consider using wood or brick instead of wood.

Can an electrical panel be outside?
A breaker box outside, near your electric meter, is essential for several reasons. It provides accessibility for homeowners and utility workers, allowing quick access in emergencies or maintenance. It also minimizes the risk of fire or electrical hazards, making it easier to contain potential dangers outside the living space. In older homes, having a breaker box outside can free up valuable indoor real estate. It is standard in regions with moderate to warm climates, but may vary depending on local building codes and regulations.
An outside breaker box is a metal cabinet or enclosure with several circuit breakers or fuses controlling power to different areas or appliances. It is usually labeled for easy identification. Consult a licensed electrician or local authorities for specific requirements in your area.
Is it bad to have a breaker box outside?
Flipping the main breaker should be done cautiously and only when necessary, as turning off it cuts power to all circuits, causing lights and appliances to lose power until they are turned back on. Having a breaker box outside your home enhances accessibility, safety, and space efficiency. Understanding its purpose and functionality can help homeowners manage their electrical systems and respond effectively to potential issues. Contact qualified professionals for guidance if you have concerns or questions.
What is the best electrical panel to install?
Schneider Electric is a reputable brand known for its high-quality electrical panels, known for their durability, strength, and flexibility. Square D panels, manufactured by Schneider Electric, are known for their heavy solid metal construction and range from smaller sub-panels to higher capacity 200-amp panels. These panels can be installed in flush and surface mountings, making them suitable for smaller homes like 1-bedroom or 2-bedroom apartments. Schneider Electric’s Square D 100-amp panels have 6 spaces for mounting the main breaker and 5 double-pole breakers or 10 single-pole ones, making them suitable for smaller homes.
Are electrical panels on interior or exterior walls?
In accordance with the prevailing building code, the location of the panel is specified. In the event that such placement is required by regulatory standards, it is permissible to situate the panel in an exterior location. In the event that this is not feasible, it is preferable to situate the panel internally in order to facilitate superior control and protection. It is imperative that a quality panel is installed by a professional to ensure optimal results. In conclusion, the decision regarding the optimal location for the panel is contingent upon the specific requirements of the residence in question.
Should electrical box be inside or outside?
Outdoor breaker boxes are crucial for reducing the risk of fires caused by electrical faults or malfunctions, as they are located away from combustible materials. Indoor breaker boxes, on the other hand, may be in close proximity to these materials, increasing the risk of fire in emergencies. Many homes have their electrical panels, breaker boxes, or fuse boxes outside, providing easier access for workers and emergency responders, more space for maintenance, and easier repairs.
The breaker box is typically installed on an exterior wall of the residential space, close to the main electrical service entrance. Proper installation and protection from environmental factors, such as rain or snow, are essential to prevent damage. Following local codes and regulations is also essential for safety and compliance.

Why are circuit breakers outside?
Breaker boxes are located outside the house to provide easier access for electrical workers and emergency responders. They eliminate the need for workers to enter the home during emergencies or power outages. Additionally, having a breaker box outside allows for more space for maintenance and repairs, making it a necessary component of the electrical system. Many residential homes are designed this way for safety purposes. Indoor and outdoor breaker boxes are essential components of a home’s electrical system, controlling the flow of electricity to appliances and devices.
Why are power boxes outside the house?
The main breaker outside a house offers easier access for electrical workers and emergency responders, whereas indoor breaker boxes can be difficult to reach. Outdoor breaker boxes provide more space for maintenance and repairs, preventing heat buildup and improving overall efficiency. They also reduce the risk of fire due to their distance from combustible materials, while indoor breaker boxes may be in close proximity, increasing the risk of fire in case of an emergency. Both indoor and outdoor breaker boxes function similarly, but outdoor breaker boxes offer more flexibility and safety.
Where is the best place for an electrical panel in a house?
The garage and basement are optimal locations for the installation of electrical panel doors, as they are readily accessible and situated out of view.
Where is the best place to put a panel box?
The basement and garage are the optimal locations for the electrical panel, as they allow professionals to access the wiring and prevent the panel from being situated in areas with high levels of foot traffic, such as the family room or bathroom.
📹 DIY Sub Panel Install: COMPLETE Tutorial, Save Thousands!
Installing an electrical sub panel yourself can save you hundreds or even thousands of dollars. Learn about the requirements for …
You could have done a better job explaining what would happen if the neutral and ground were not separated in the sub Panel. Would the breaker still trip when there is a ground fault? And when it did trip, wouldn’t that instantly resolve any potential shock hazard between the main and sub-panel? It’s too bad you didn’t explain this well. 😞 You failed to thoroughly explain what would happen if there is a short while the neutral and ground are not separated in the sub Panel. You should have explained the “floating ground” and HOW this can increase the risk of electrical shock and damage electrical equipment. You spent too much time explaining background concepts and very little time explaining your main thesis.
From looking through the comments it seems the ground outside the main panel directly to the ground rod is the top issue mentioned. Most say there should be a 4th wire in the conduit with the lines as a dedicated ground within the main panel. Also with the four wires (if the ground is included) the conduit should be upsized to be within the 40% rule. Other than that, great job. Thanks for the article. Nicely done. Good camera work, editing and a clear explanation. Appreciate you.
I just added added a Square D sub-panel off my main. It is a lot nicer than my existing HC/Eaton panel. I have a lot of DIY electrical experience and I spend a lot of time looking up code when I’m working on projects. You did convince me to finally order a torque screwdriver. One additional step I took was to coat my exposed leads with anti-corrosion grease. My panels are in the garage and I’m fairly close to the ocean.
I installed a lot of120/240, 120/208, 240, & 480/277 volt single & three phase subpanels and never ran a ground from anything BUT the panel that feeds it. Did not see you seal the wires in outside of conduit to prevent condensation build up. Did not see him install the required gasket on the 1″ LB. On my own house I ran a jumper ground to each of those ground bars and not depend on screws to provide a path for thousands of amps during a short circuit. The NEC has never allowed you to screw a chase hippie into any coupling ( not what u called coupler ) . Reason being rigid electrical couplings have a tapered thread and chase hippie do not have tapered threads. I would have ran a copper ground wire from service panel to sub panel and go the extra yard and install a not code required grounding lock but or grounding bushing on 1″ EMT connector inside service panel. If you are in the Latest NEC code cycle you would need combination AFCI breakers for all circuits 50 amps and less in the garage. ( both 120’& 240 volt circuits ). Some locations do not require that for hard wired 50 amp 240 volt EV chargers.
Thank you for the informative article. I would caution everyone about the use of a metal tape measure, however, as seen around the 7:30 minute mark. It is generally advisable to use non-conductive measuring tools around exposed electrical wiring. Folding rules made of wood or non-conductive plastic would be preferable to the metal tape measure in this application.
Good info. I have a couple of comments. Your ground wire should run in the same conduit that your current carrying conductors are in. Second, you should always isolate the neutral bonding in the sub panel. The only place that a neutral should be bonded to ground is at the first means of disconnect, which would be at the main panel.
Well done! Fantastic website. I wish more homeowners would watch these articles; it could save some lives and expensive headaches. One should always make sure they/electrician have full understanding of local and updated NEC. I took a whole semester long class which focused only on reading and working with NEC; it was a very interesting class. The permitting process is in place to protect you, the homeowner.
Just an observation. On the main coming into the subpanel i usually put a loop there so if something should happen there is enough wire to change it. Ive never had to change it in any panel though. The other thing that loop does is release tension on the wires at where they come out of conduit. Although once done everything should be secured at entrance in each box.
Great info. Just rewired my sons detached garage sub panel that was totally done wrong by previous owner that did not have full understanding of “Local and National” NEC. They had bonded the Neutral and Ground buss with the ‘GREEN’ screw. MANY other bad wiring issues too. And the MAIN panel inside the house was also done wrong as it is a Modular Home and the ‘Main’ disconnect is on the power pole strike detached from the house, so the first panel inside is also a Sub Panel and it too was bonded with the GREEN screw. Again, many bad wiring issues inside, open grounds and loose HOT and Neutrals at outlets and switches. Retired “Pole Dancer” and low volt electrician of 43 years. Did High voltage Power Line work until my knees said no more hiking poles.
With all due respect you should not be making a tutorial if you are not a qualified electrician. There is many problems with this installation. 1. Most importantly you are working in a LIVE panel. Not only did you not get the power company to pull the meter but you didn’t even bother turning the main off. Others following your tutorial could easily die, yet you mentioned nothing of the dangers of working in a live panel. 2. Your sub panel needs a DIRECT connection to the ground in your main panel, not just to foundation steel or the grounding electrode. 3. You used the inside concentric knockout of the sub pannel without a grounding bushing. Unless you have the same size knockout as connector, you need a ground bushing 4. You used an MC connector for your ground wire, that connector is only rated for MC. This probably isn’t a big deal since the ground wire doesn’t even need insulation.
You didn’t discuss the one thing I was really interested to learn about, which is are subpanel ground supposed to be linked to neutrals? From what I saw, your subpanel neutrals are isolated from ground, which I think is correct and different from the main panel in which the neutral is tied to the ground. Thanks for the great tutorial. Edit – I see that someone else explained yes grounds should be isolated, but also not earth-grounded, but rather run back (isolated) to the main panel.
In NJ this panel would fail inspection. The ground wire in the subpanel should be run with conductors from the main panel. Neutral and Grounds are isolated from each other in the subpanel. Ground bonded to subpanel. Neutral is not bonded to the subpanel. A second panel or sub panel should have the neutral and ground terminals or bars isolated from each other, this is why the main circuit feed to the sub panel must have 4 wires, with a dedicated insulated wire for the neutral and a separate wire for the ground. All the ground wires bond back at the main panel together with the neutrals. The sub panel neutral bar or terminal should not be bonded to the enclosure or the ground of the sub panel. The sub panel ground should not have a ground rod tied to it. The bonding for the main ground sources such as a ground rod is made at the main panel where all the grounds are bonded together as well.
If you install the subpanel into the wall like this, there is pretty much no insulation in that spot. Furthermore, if this is a living space in the colder climate then warm moist air will be hitting the cold surfaces of the panel and water can start to condensate on the panel, which is not desirable. For those reasons I actually think you can and you should surface mount a panel.
I read through most of the comments. Some good some not so good. One thing. Ground conductors that are not bare are required by NEC to be identified as green. Also, if you are going to install conductors for 100 amps as in this case #2 cu in a dwelling, then there is absolutely no reason to put anything smaller amp breaker. Just a total waste of money.
Technically your reframing job to install the panel doesn’t meet code. There should be “jacks” installed under your bottom horizontal run to the bottom plate of the wall to support the load transferred around the box. Right now your bottom horizontal plate is relying on the nails holding it in place to support the roof load. The framework should be just like the installation of a window in a load bearing wall.
Thank you for this article. Question: Why is the panel less then the 36″ you said NEC code says is required from any wall left or right of the panel? I have this same situation about to come up for a main panel I need redone but it’s probably only 12 inches from the wall (has to be grandfathered being so old but if I do it new I want to be in compliance)
I had to strip some big 1 or 2 gauge wire not to long ago. I used a baby pipe cutter for copper tubing. I never seen it done before but it was in my hands reach when I was needing to strip them to make battery cables for my old 53 Chevy truck. I had them out as I used copper tubbing that just fit over then I crimp and solder the tubing to the wire a inch longer than my wire. I flatten the tubing in a vise and round the corners off of the flattened pipe and then drill a hole to attach to the starter. Us DIY folks need to stick together.
Yep…. same here. I spent all that time spec-ing out which box I’d buy… I bought a Square D QO 12 space/24 circuit outdoor box… only to find out that A) the top two knockouts were already out, (and I don’t need both of those spaces, so now I have to fill in one them) and B) my cover has 16 spaces, not 12 – so those last 4 spaces are null… pointless… deceiving… orphans. YET, Square D does make a 12-space cover for their “Homeline” 125-amp box. I mean, I’ve heard of saving a few pennies in the manufacturing process by consolidating… but come on now.
