This is a fairly common situation: A 200 amp 480V meter/main w/breaker panel that needs to feed a 50 KVA stepdown transformer. The breaker lugs are rated down to #6 wire and the 100 amp primary protection fused disconnect lugs only accept up to #1/0 wire. Is there a good reason why there is not an exception in the tap rule that would allow feeding the disconnect from the breaker with #2 instead of having to go full sized and use pin terminals? A fused 200 amp meter/main solves the problem with 110 Amp fuses but they are not always available.
