In this regard, what is the electrical box called?
A distribution board (also known as panelboard, breaker panel, or electric panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
One may also ask, should I use plastic or metal electrical boxes? Plastic boxes don't use metal cable clamps and do not provide the required grounding path. Metal electrical boxes are primarily used with metal-sheathed or "BX" wiring. However, they can also be used with Romex or NM wiring if desired. Most new residential electrical systems use Romex and plastic boxes.
Similarly, it is asked, what are the different types of electrical boxes?
There are round, square, retangular, shallow, weatherproof, and extension boxes. Electrical boxes come in plastic and metal varieties. Plastic boxes are non-conductive and are relatively inexpensive. They come in different styles that either nail on or are the cut-in variety.
What is the difference between a 1 gang and 2 gang socket?
If you have a dimmer switch they are described in the same way; a 1 gang dimmer switch will have a single dimmer on the plate, and a 2 gang dimmer switch will have 2 dimmers and so on. A 1 gang switch will control a single lighting circuit, and with a 2 gang switch you can control two lighting circuits, and so on.
