Not to side-step your question, but why would a 208V circuit, normally found in a commercial setting, be run without a EGC in the first place? What kind of wiring method was used?
NM cable from panel to a/c disconnect which is mounted on the brick exterior wall and then UF from a/c disconnect to a/c compressor.Before myself or SD515 can comment little more on this one what type of wiring methold it did use like NM cable or EMT conduit or others ??
Once we know what type of wiring methold it did bring to the disconnect swtich we will go from there.
Merci,

Not to doubt the condition of the EGC, but why was the A/C tech checking the condition of the ground path since the ground path will not affect the operation of the condenser?A unit was being serviced and the a/c tech said that the egc was open somewhere in the interior walls of the building between the panel and the unit's disconnect
I have no idea.Not to doubt the condition of the EGC, but why was the A/C tech checking the condition of the ground path since the ground path will not affect the operation of the condenser?
Yes..and there is no continuity between the end of the egc in the disconnect and the end of the egc in the panel.The first question would be, is there an EGC coming into the disconnect.
Again, I have no idea.Second question would be, if this is in romex as stated, how would the ground wire get broken without any damage to the other conductors in the romex cable.
My original question was:
Does the EGC (equipment grounding conductor) have to be run with the ungrounded conductors of a line-to-line circuit (208 V)back to the originating breaker panel? or can it be just run to another piece of equipment that is fed from another panel?
