Jerry:
At a recent John Wiles seminar, John declared that this scenario is not a
tap and is therefore not covered under the tap rule. This was news to me,
but Wiles is considered some sort of guru in compliance discussions.

Wreches,
I have a system where we are tapping onto the bus bars of a 1200 amp panel
fed by a 1200 amp main breaker. The easy place to tap onto the bus bars
is the load side of the breaker using the existing bolts.
The inverter and utility fused disco are about 200 ft away, and the tap
conductors travel about15ft in EMT conduit before leaving the
building. After that the circuit is outdoors. NEC 240.21(B)5 allows taps
of unlimited length for conductors located outside of a building, except
at the point of load (in this case supply) termination.
Can 20ft of conductor inside the building be covered by being "at the
point of load termination", or do I have to comply with NEC 240.21(B)2 and
have an OCPD within 25'?
The construction foreman for this project is buddies with the inspector,
so getting a signed permit won't be a problem but I want this to be a code
compliant system. Can anyone lend some insight to the spirit of
240.21(B)2 and 5?
Sorry if this has been discussed before, but searching didn't yield any
results.
Best,
Jerry Caldwell
