Having a structure withe two or more service disconnects in separate enclosures, does the GEC tap that enters into each enclosure from the common GEC have to be an irreversible splice?
I'm referring to 250.64D and just trying to "get this right".
My current example scenario has two main breaker service panels, side by side. One is for single-phase loads, the other is for 3-phase loads (240v). When running my GEC from the metal underground water line electrode back to the panels what is the best (compliant) way to tap off that GEC for each service panel. GEC will be 4awg bare copper.
What I want to do is run the GEC back to the panels and take it into (terminate) the 3-phase panel, with a 4awg tap that terminates in the single phase panel. Do I have to use an irreversible crimp for that splice, or can I use something like a split bolt connection?
Thanks!
