Key Considerations Before Purchasing Outdoor Electrical Boxes
What is the outside electrical box called?
Electric circuit breakers in a distribution board also go by the names panel, breaker, or electric panel. They divide electric power into a number of sub-circuits while a protective fuse or circuit breaker is provided for each circuit in a common enclosure.
Why are electrical boxes outside?
A new regulation has made it so that an electrical box should be permanently attached to the exterior of a home. The fire department imposed this regulation in part because firefighters will be able to swiftly shut off all the electricity if they arrive at a house that is on fire.
How do you seal an outdoor electrical box?
Before you screw the box to the wall you need to apply a paintable silicone acrylic caulk around the entry hole and the back of the box. An external ear or recess should be incorporated into the box to serve as a mounting base.
