Below panel Some homes require added solution panels (called sub panels) that distribute electrical power to a group of circuits.


Electric cable television The electric wire used for many residential applications today is commonly referred to as Romex wire. The sheathing may also be color coded to further aid in determining cord scale and also use.


NM 12-2 cable television (yellow sheathing) is made use of for receptacles and also 20amp circuits.
