I have 30kva transformer hung above suspended ceiling. Primary is in electrical room 50 amps breaker. I have disconnecting non fused switch 60 amp next to primary of transformer above celing in sight. Secondary conductor feed panelboard below room. The secondary conductor would require overcurrent protection if more than 10 feet and in case less than 10 feet?
Table 450.3 (b) says not req but 240.21 (C)(2) or (6) says less than 10 feet not req more than 10 feet needs circuit breaker.
