The home was built in 1997 within a small city.
The service comes into a 200 Amp Cutler H panel on exterior, and a 100 Amp breaker feeds the sub distribution panel in the storage area.
In the storage area sub, the conductors come into a 100-Amp breaker at the top of the panel with a 3-wire feed. The rest of the breakers are below, all 20 Amp.
Are there different requirements because the conductors feed the breaker, not the panel itself ?
Should I comment that ‘by today’s standards a 4-wire,’ etc, would be needed’ – or call it as deficient and defer to electrician.
By my understanding, the sub should have a 4-wire feed, but what year did this start?
Not sure which year of the NEC was in effect when home was built, mid 80’s by guess
Harry HomeOwner is the Seller and did all the original wiring when the home was built, I need to be able to explain what I state. :mrgreen:
