Line Breaker
Use a 60 amp line (and breaker) for a 30 amp appliance as well as a 60 amp appliance?
I have a 60 amp line, breaker and plug installed. I would like to plug both a 30 amp appliance and a 60 amp one into the line but at different times. Would the 30 amp appliance be able to be plugged into the line? Would this be safe? Thanks
There is a code exception that allows cooktops to be connected into range circuits without providing lower overcurrent protection, but I don’t know if it would apply because your question is too vague.
You could (if space allows) install 30 amp fusing at the location of the 30 amp receptacle, and a switch to service the fusing. A transfer switch may not be required, multiple outlets are allowed on a circuit, fixed in place and non coincidental loads rules would have to be considered, but those weren’t provided in your question.
Generally though, you would not be able to, the code says 30 amp outlets are to be protected by 30 amp overcurrent protection. The point is a 30 amp receptacle should not be installed on a 60 amp breaker, because your 30 amp appliance could be failing, drawing 60 amps, melting down and starting a fire, and the breaker would not shut off, but since the 30 receptacle is required to be protected by a 30 amp breaker, the 60 amp draw would shut down the fire source.
