Hello! I've been scouring my code book and cant find a specific answer to my issue. When upgrading an existing 3 wire system with a separate service disconnect current code require an EGC run to the breaker panel (which is considered a sub-panel). My question is, if there is an existing 3 conductor bundle (SER cable), is it permissible to run a separate EGC conductor? Our local AHJs are insisting that a new 4 conductor bundle be run in lieu of adding the single conductor. Can anyone point out where NEC deals with this?
Thanks in advance!
