Code Question Of The Day

Monday, February 06, 2012
Question:

Subject: Re: CQD Tuesday, January 31, 2012

What about the Exception in 250.148? It seems that it would not be necessary to splice the individual EGCs together. EGCs brought in and connected to their devices individually seems to satisfy (D) also.

Always good to have this brain stimulation in the morning, thanks Charlie.

Answer:

Hey Scott, thanks for commenting.

Section 250.146(D) applies only to isolated grounding equipment grounding conductors, while 250.148 applies to all other branch circuit equipment grounding conductors (wire types). Removal of the device should not break the required equipment grounding conductor continuity (250.148(B).

 

Section: 250.146(D), 250.148
