How Do Electrical Box Extenders Work?

A report by the Electrical Safety Foundation International estimates 51,000 household fires on an annual basis, 28,000 of which are caused due to arcing faults. Furthermore, electrical receptacles are responsible for causing 5,300 fires, 40 deaths, and 100 injuries annually.

This doesn’t end here! NFPA estimates that around 3,340 commercial fires were reported every year between 2007 and 2011. Electrical distribution was the second leading cause for these fires, contributing to 15% of property damage.

The National Electrical Code requires residential and commercial properties to comply with electrical installation standards in order to avoid potential fire hazards. The code requires the use of electrical box extenders with electrical outlets to ensure they don’t bury more than 6mm into the wall.

Here’s a brief overview of how electrical box extenders work.

Getting Into the Details of Electrical Box Extenders

The purpose of an electrical box extender is to ensure your electrical outlets aren’t sitting recessed into the wall.

The big question is: when do you need an electrical box extender? Maybe your contractor did a poor job with your drywall, or maybe your tiles overlapped your current electrical outlets. Either way, it leaves you with a recessed box that’s not in line with your wall’s surface. This is where the need for electrical box extenders comes in.

They fit snugly with your current electrical box leaving no space between the two. It provides a flushed, sealed enclosure against the wall surface.

Primarily used for fixing recessed electrical outlets, these extenders can also be used to protect metal boxes from arcing. This is done by enveloping their conducting surface with the help of extenders.

The installation of extender boxes is what follows next. Here’s a step by step guide on how to install a metal box extender:

  • Start with shutting off your power source.
  • Remove your outlet’s cover plate by unscrewing it.
  • Check for current before touching the wires to avoid being electrocuted.
  • Measure the distance between your outlet box and your wall’s surface.
  • Choose a box extender design that meets the thickness requirements.
  • Slide the extender over the wires and outlet box.
  • Be sure to check that the inner flange is facing the box and not the front.
  • You’ll need longer screws if the thickness of your extender box exceeds ½ inches.
  • Tighten screws to place your device is in a firm position.
  • Replace the cover plate and restore power.
  • Check your switches and power outlets for proper working.
