I really don't see why it would be a problem but though I would ask first. Thanks, K [Reply]   [No Email]

Green insulated is preferred but not nessacery. The grounding is the most important wire in an electric circuit when there is a problem. Did a service call years ago where a 2 pole 30 amp fuse disconnect was added to a old split phase fuse box. The Romex connector was tighted all the way down on the cable and the ground wire was cut off and not connected, After 15 years or so the red conductor became knicked and energized the entire fuse box because of no pathway to ground to short out. Note this was tapped straight from the main lugs with no overload protection untill you got out to the transformer outside on the pole. 100amp 120/240 volt service. Customer got a real bad shock from this condition and it did short out when the fuse box door cover was opened and made contact with the fused disconnect this could of killed somebody very easily Grounds are very important Bart Master electrician.

The only reason I ask is I know when you buy MC cable the ground is usually not bare (ie, the green wire). K [Reply]  [No Email]

I am pretty sure that thhe grounding conductor can be bare. ANy more details would help, though. D. [Reply]  [No Email]
