We have a 30amp 480volt circuit that feeds a electric water heater, On the same branch circuit is a 30amp 480volt receptacle solely for the purpose of the heater breaking down and out of service. There is a portable heater to plug into the receptacle.It is not intended to ever run both at one time,If they did it would trip the circuit breaker, my question is should I label the receptacle as to one unit only at a time?
