I came across a new installation in the industrial facility I work in. It is a 480 volt isolation transformer 45kva feeding a 100 amp panel for heat trace loads. No wiring is installed yet just the transformer and the panel. If the primary is fed with a 50 amp breaker will this be a violation since the panel will be capable of exceeding the transformer capacity even if the load isn't over the capacity at the time of installation? Hope I make sense here.
