[RE-wrenches] Bonding bushings?

[August Goers]

Jesse,

Any metallic raceway that has a GEC running through it needs bonding. So,
if you've got the Enphase DC-GEC running through it then, yes, it would
need bonding fittings. At least that's my take on it.

Check out NEC 250.64(E) towards the second half of the paragraph. 2011 NEC
has a nice clarification point and directs you to 250.92(B)(2) through
(B)(4).

Best,

August

If you are using micro inverters and terminating them in an AC combiner
panel, does the feed for the AC combiner panel (125A) need to have bonding
bushings for the ground wire?  In other words is this ground wire a
GEC/Equipment ground like might be used if running an inverter output to a
panel?  The raceway is already in and is EMT.

Thanks!
