I have resently needed to increase a 20 outlet circuit to #4 wire for voltage drop.
Unfortunatly the conduit has already been sized 3/4".
2#4 and 1-#12 ground wire will meet the fill calculations.
I have read NEC section 250-118 and 250-122.
The conduit system is RMC with all threaded joints back to the source.
My question is this an acceptable installaion?
The rigid conduit is an acceptable EGC by itself.
The #12 is a supplimental parallel EGC.
Is this correct.
