Electrical Wiring in the Home/Residential wiring using EMT
Two questions. How many #12AWG conductors allowed in a 1/2" EMT? This is for standard 120VAC 20A residential use. Also, are the EMT pipes, boxes and connections acceptable for ground continuity between outlets or must a separate wire be used? Thanks!
One the first question, it depends on the specific conductor used as the number of conductors in a given conduit is determined by the diameter of the conductor and each type of insulation has a different given diameter. With the proper connectors EMT can be used as the ground, but I have never used it in this manner as it can always be damaged and the safest method is to use a separate ground conductor. Thanks J
