Frequently Asked Questions (FAQs)

1. Can I replace metal electrical box with plastic?

Homeowners can replace their metal electrical box with plastic if non-metallic cables come in and out of the box. However, the downside of plastic electrical boxes is that they distort or crack under stress, and PVC can melt due to overheating.

2. Do metal electrical boxes need to be grounded?

yes, the box should be grounded. It should not be grounded through the devices, but by means of a machine screw, clip, or through metal conduit.

3. What metal are electrical boxes made of?

PVC has become the standard electrical box material, especially for DIYers. Lightweight and easy to work with, many of them also come with built-in clamps for wiring. Though PVC can melt when overheated, it does not conduct electricity like metal does.
