Re: grounded conductor
Hello guys,
Here is a perfect example of using the proper terminology, and having enough information to be able to answer the question. I am going to take a stab at it.
rv3152 uses the term 'grounding conductor'. Does he mean Grounding Electrode Conductor (GEC) or Equipment Grounding Conductor (EGC)?
If he means the GEC, that conductor is installed (usually) at the first point of disconnect, and the installer does not run it in the raceway to the panel after the disconnect(I am 'assuming the panel is not close enough for immediate entry location of service disconnect). The GEC is sized according to table 250.66 based on the size of the service entrance conductors, not the size of the service disconnect.
If he means EGC, then he can run the conductor in the raceway. But... the conductors on the load side of the service disconnect are not service conductors, the are feeder conductors. The point of running them in the raceway is moot. The EGC is sized to table 250.122 and is based on the size of the overcurrent protective device (fuse or circuit breaker).
I hope this helps,
Pierre
