Surface-mounted electrical boxes are essential for all electrical fixtures, including receptacles, ceiling fans, and outside outlets. Outdoor boxes are built to withstand outdoor elements and often come with weatherproof covers or gaskets to protect the electrical components from moisture. Junction boxes join multiple wires and provide a centralized organization for electrical connections.
Materials for electrical boxes include metal and plastic. Most indoor metal boxes are steel, while indoor plastic boxes are PVC or fiberglass. Weatherproof metal boxes offer excellent protection, while plastic boxes are lightweight, corrosion-resistant, and suitable for most applications.
Outdoor junction boxes come in various styles, including hinged covers or knockouts, wall mounted or pole mounted. Old work boxes are designed to slip into an opening in the wall and be fastened tight from the outside, while new work boxes have nails preinstalled. Weatherproof boxes are designed for outdoor environments or damp or wet indoor locations and are available in one- and two-gang configurations.
Plastic boxes are the most common choice for residential wiring projects due to their lightweight, easy-to-install, and less expensive nature. Specific boxes are designed for indoor or outdoor use, while others are made for installation behind or outside of walls. They can contain light switches, and pedestal outlet boxes stand on their own and focus on protecting outdoor power outlets. Both plastic and metal models are available for outdoor boxes and are suitable for various uses.
In summary, both metal and plastic electrical boxes are essential for home wiring projects, providing excellent protection and organization for electrical connections.

Can you have an electrical box outside?
An outdoor electrical box is a convenient and safe device, but misusing it can cause severe injury. It’s crucial to prevent children from accessing equipment like pad-mount transformers and secondary pedestals. Opening outdoor electrical equipment can cause physical harm, including burns, shocks, and electrocution. It’s essential not to open the box without proper knowledge, obstruct access, or ignore signs of damage. If you notice holes, broken locks, missing pins, or other signs of damage, report them to the utility immediately.
What are the requirements for an exterior outlet box?
Outdoor receptacles must be protected by ground-fault circuit-interrupter (GFCI) systems, with exceptions for snow-melting or deicing equipment. These protections can be provided by GFCI receptacles or circuit breakers. Homes should have at least one outdoor receptacle at the front and rear of the house, accessible from the ground and no more than 6 1/2 feet above grade. Attached decks and balconies with interior access should have a receptacle no more than 6 1/2 feet above the deck or balcony walking surface.
Receptacles in damp locations must be weather-resistant and have a weatherproof cover, while those exposed to weather must be weather-resistant and have a weatherproof “in-use” cover. A permanent swimming pool must have an electrical receptacle no closer than 6 feet and no further than 20 feet from the closest edge of the pool, with GFCI protection. Receptacles used to power pump systems on pools and spas must be no closer than 10 feet from the inside walls of a permanent pool, spa, or hot tub if not-GFCI protected, and no closer than 6 feet from the inside walls if GFCI protected.
Rules for outdoor lighting are primarily about using fixtures rated for use in damp or wet locations. Light fixtures in wet/exposed areas must be listed for wet locations, while fixtures in damp areas must be listed for damp locations. Surface-mounted electrical boxes must be raintight/weatherproof, and low-voltage lighting systems must be listed by an approved testing agency. Switches controlling pool or spa lights or pumps must be located at least 5 feet from the outside walls of the pool or spa unless separated by a wall.
What type of box is required for all electrical boxes in exterior walls?
Metal junction boxes are frequently required by local building codes due to their durability and long-lasting performance.
What type of box do I need for exterior light?
Weatherproof outdoor boxes are sealed enclosures utilized for mounting on exterior walls, roof overhangs, and decks for the installation of outdoor receptacles and light fixtures. It is imperative that the outdoor cover or fixture be rated for damp or wet locations. Plastic outdoor boxes are typically manufactured from high-impact PVC, whereas metal outdoor boxes are typically produced from aluminum.
What are those electrical boxes outside?
A pad-mounted transformer is a green box in your yard or neighbor’s yard that changes voltage from higher levels to a level used in homes for electronics, appliances, and lighting. These transformers are vital for providing electricity to at least one home, usually to several. Pad-mounted transformers, switch boxes, and pedestals are at ground level, while overhead power lines are mounted on utility poles and substations protected by security fences. Burying power lines reduces potential system damage from high winds and severe storms.
What type of outlet for outdoors?
Outdoor outlets are safe, as long as they are properly protected. GFCI outlets, which are equipped with sensors that detect small changes in electrical current, are a common way to protect them from accidental electrocution. These outlets are also often covered to protect them from wind, rain, dirt, and other elements.
In summary, outdoor electrical outlets are a great way to increase the versatility of outdoor spaces. They can be used for powering electric lawn equipment, special lighting, or other equipment. If you need additional outlets or don’t have any, contact your local electrician for advice on safe placement and usage. They can also install them quickly and efficiently. Overall, outdoor electrical outlets are a valuable addition to any outdoor space, providing a safe and efficient way to power your outdoor devices.
What is the electrical box on the outside of the house?
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.

Can you use plastic boxes for exterior outlets?
The utilization of plastic as a service plug or outdoor outlet is permissible, contingent upon its deployment in conjunction with a weather-resistant outlet and cover. The installation of these boxes within a wall structure effectively protects them from exposure to ultraviolet radiation, extreme temperatures, and potential damage from wild animals, thereby ensuring their safety.
What is the outdoor electrical box called?
An outdoor electrical box is an essential safety measure to protect electrical wiring and equipment from environmental factors and dangerous currents. These boxes are made from materials like mild steel, stainless steel, and polyester, and can prevent dust and water from entering. They also protect electrical components from higher temperatures when fitted with cooling fans and systems. Electrical boxes are a health and safety precaution, as they can prevent business owners from liability in South Africa for injuries caused by shock to employees. To avoid costly lawsuits and potential damage to a company, it is crucial for electrical boxes to seal properly, be made of hardy materials, lock, and be equipped with other precautionary measures.
Do outdoor electrical boxes need to be metal?
While plastic electrical boxes can be replaced by metal ones for non-metallic cables, it is important to note that they may distort or crack under stress. Additionally, PVC can melt due to overheating, which is a significant concern when working with electrical components.

what the heck area are you in? I’ve never seen some of those plastic boxes you have! pretty neat 🙂 Usually get the blue carlon ones here but 2021-2022 we were having a time getting boxes in my area, local suppliers started getting in these generic black boxes that I had not seen before, and when we were really desperate, we’d grab fiberglass. But never seen some of these gray plastic boxes like you have there here in east tennessee 🙂 pretty cool!
