I have a home pottery studio which has its own 100A sub panel, properly permitted and installed. There is one 240v 50A circuit that runs to the kiln room and powers a kiln. Plus a handful of other circuits which power lights, plugs, etc
We are adding a second smaller kiln to that same room, which requires 240v 30A. We will NEVER run both kilns simultaneously. As the subpanel is a couple rooms away, with no crawl space or attic, pulling a new circuit from the subpanel to the kiln room is difficult/expensive.
Can I /should I:
- Add a subpanel to the kiln room with a 50A circuit for the old kiln and 30A circuit and 14-30 receptacle for the new kiln.
- Simply unplug the old and plug the new small kiln into the existing 14-50 receptacle when needed (using a 14-50 to 14-30 adapter as necessary)
- Add a DPDT switch ( like a manual generator transfer switch) which would power the 50A receptacle or the 30A receptacle (but not both at the same time)
- Other suggestions?
