I know, a subject kinda beat to death but
I have looked on line about generator
grounding and all of it is for standby
and I get is more confused. I know there
is expertise on this forum. Here are the
facts, I have a large barn on the
property that used to be grid powered via
sub panel but it was disconnected years
ago. I want to repower the barn with an
old generator I recently purchased. There
will be no grid connection, only
generator as prime power. The generator
is 3 wire, 2 lines and one nuetral, 220
between the lines, 110 line to neutral. I
have that all wired to the panel. The
neutral is not bonded to the frame of the
generator. As I understand it the sub
panel was incorrectly wired as it was
used previously as the neutrals and
ground are bonded and there is a ground
rod with #6 bare copper running to the
neutral buss. So, my question is how do
I, or do I? ground this set up? I
remember reading here that grounding
certain generator installations would
create a hazard. If it makes any
difference the generator has no tags and
Id guess 4KW. Just running a few lights
and occasional power tools.
