Inside the Wall: Your Metal Electrical Box and the Risk of Arcing

Electrical malfunctions or failures remain one of the top causes of home structure fires in the United States.

The NFPA estimates that fire departments in the U.S. respond to an annual average of 45,210 home structure fires involving electrical malfunctions or failures.

The common theme in most home electrical fire incidents?

Arcing!

What is arcing?

Arcing is defined as an electrical phenomenon characterized by a high-temperature electric discharge between two conductors across a medium or an air gap.

Typically, arcing is associated with faulty wiring and loose electrical connections. However, sometimes, the risk of arcing may also increase depending on the type of electrical box installed inside a wall.

An electrical box serves as a transition or end point for electrical wires. Outlets, switches, ceiling fans, and lights are just a few of the devices that are installed in an electrical box.

There are two types of electrical boxes that are commonly available in the market: plastic electrical boxes and metal electrical boxes.

Most new homes that are built today use plastic electrical boxes. These boxes are cheap, lightweight, easy to install, and provide safe levels of electrical insulation.

Metal electrical boxes, on the other hand, are commonly found in old homes. They are ultra-strong, melt-proof, and provide a strong attachment with the studs. However, their construction makes them susceptible to arcing.

Metal boxes and arcing

Metal boxes inherently conduct electricity. A device installed inside a metal electrical box with metal screws can act as a second conductor, creating the perfect conditions for an electric discharge.

Do you have a metal electrical box installed in your house? What steps have you taken to prevent arcing inside it?

If you haven’t, and you’re looking for a reliable solution, then an electrical box extender is just the solution you need.

What is an electrical box extender?

An electrical box extender is a device installed on top of an electrical box to provide a flushed, sealed enclosure against the wall surface.

Electrical box extenders are primarily used to fix recessed electrical outlets. However, they can also be used to protect metal boxes against arcing by enveloping their metal conducting surface.
