Got a call from a contractor stating that the inspector was requiring him to size an equipment ground in a feeder tap based on the feeder main and not the size of tapped main he was installing. The inspector was correct that the equipment grounds installed with the feeder taps would have to be sized based on the feeder main and not the taps main. This will only apply when a wire type equipment ground is installed, if you are using metal nipples as the equipment ground then this section does not apply. In the picture that I used the nipples are metal because I could not find a picture with PVC nipples, So if these nipples were PVC then the equipment grounds installed would have to be based on this section. The last part of this section tells us that the equipment ground will not have to be larger than the tap conductors.
If you can not see the whole picture just click on it.
Got a question email me @ jleccemail@hotmail.com
Till next time be safe work safe.
