Hello ... 250.113 specifies the use of an equipment grounding conductor
hi, so is three wire ok ?
Is this new or existing ?/ are the walls open and the wiring accessable ?
existing open walls.
did you get my follow up question? about the powerwasher?
If it is popssible top rewire the appliance to 4 wire feed then you shouild do that
That is the existing code
ok... 4 wire becuase it is near water?
the boss and i got into a bit of an arugument about it today. i feel like 4 wire would be safer. 2 hot, one netural one ground. but i cant prove my theory.
and one other question there needs to be a disconnect if more than 50 feet of panel?
oopsy ,, that is 250.114
can i look that up myself?
The equipment grounding was always there ... it is the neutral that is now required to be separate ..
ok... how about in a wet area. like a car wash?
and when was the revision
a car wash building would have many more requirements
what is your situation ... ?? are you the owner or the contractor?
the revision was when the community or state adopted the 2008 NEC
are the cars driven thru the car wash ... or dragged thru by a belt ?
