Replace a service panel circuit breaker knockout?
Probably a dumb question but...
Replaced our electric hot water heater with a power vent gas model. I want to reuse the circuit the hot water heater was on to power the power vent so I don't have to run any new wires, etc (there is a junction box where the heater connected to the circuit that is perfect for a receptacle). Nothing else was on the hot water heater circuit.
The hot water heater circuit was 240 v, 2-pole breaker. The gas heater power vent needs 120 v. When I replace the 2-pole with a 1-pole (only going to be 15a) there will be an opening in the serivce panel cover plate. What do I do to cover that opening? Is something sold for this purpose, or do I have to fill the slot with what would be an unused breaker?
