I have a question regarding a 45KVA transformer installed near a wood cabinet, also I didn't see that NEC required a working space rule for 45 KVA transformers. please see picture for better idea,
450.21 Dry-Type Transformers Installed Indoors.
(A) Not over 112 1⁄2 kVA. Dry-type transformers installed
indoors and rated 112 1⁄2 kVA or less shall have a separation
of at least 300 mm (12 in.) from combustible material unless
separated from the combustible material by a fire resistant,
heat-insulated barrier.
Exception: This rule shall not apply to transformers rated
for 600 volts, nominal, or less that are completely enclosed,
with or without ventilating openings.
Located on front of a cabinet, left side is 3" from cabinet. transformer front cover can be removed without having to move the transformer. Please Help me.
