RE-wrenches<BR><B>Subject:</B> [RE-wrenches] Grounding Requirement
Question<BR></FONT><BR></DIV>
<DIV></DIV>Wrenches,
<DIV><BR></DIV>
<DIV>Just installed a Magnum MS-PAE battery based system on an E-Panel
distribution box and my inspector seems to have an issue with the grounding.
He is saying that I must run an additional GEC down to the ground rod
because I am dealing with two separate grounding systems. The DC and AC
side of the grounding system shares the same ground buss bar in the E-Panel so
why wouldn't a single GEC down to the ground rod suffice? The buss bar is
where the two systems get grounded together rather than at the rod. The
inspector is telling me to either dig up the rod and run an additional GEC down
to it or connect the additional GEC to the existing with an irreversible splice.
Am I missing something here? This requirement just seem redundant
and wasteful. If I do have to make the correction I will be going with the
splicing option. Some advise on irreversible splices would also be
greatly appreciated. I can't seem to source them locally and have never
used them before. Thanks for any help.
