Yes, that's fine. On a sub panel you don't want the neutral buss to
be bonded to the enclosure.

Thanks, I understand the part about the neutral buss being kept
separate from the ground buss in subpanels. And obviously the
subpanel chassis needs to be tied to the equipment ground. I was just
surprised to the subpanel chassis as part of the fault current path
for all the circuits served by the subpanel. That's fine?

Thanks, Wayne

Think about this....if that metal enclosure or any metal conduit is not
grounded.....what do you think is going to happen in the event that a
hot wire gets a nick in it...or it comes loose from its
connector....you dont ever want to have that enclosure or any metal
conduit in a situation where it can be hot. Grounding the enclosure and
any metal conduit or raceways makes perfect sense.


Ive had the fire knocked out of me before by a 4 by 4 junction box
before....hot wire loose touching the box.....box wasnt
grounded........thank goodness it wasnt a damp area.
