Trying to determine the maximum breaker size I can use for LED site lighting. NEC 210.23 (B) allows the use of a 30 amp circuit for heavy-duty lampholders. NEC 210.23 (C) also allows 40 and 50 amp circuits for heavy-duty lampholders. My understanding that heavy-duty lamp holders are those with a mogul base. Do LED fixture qualify for this? Unfortunately the 2011 NEC (used in my state) has not caught up with LED fixtures yet.
