I want to run a small kiln. The specs say 115V, 15A, Amp fuse size 20, wire 12, plug type 5-20P. Can I plug into a regular household circuit?

  • How long is the extension cord? What gauge are the wires in the cord? – wallyk Nov 27 '16 at 6:37

No, the 5-20P configuration will only fit circuits designed for and equipped with a 20 amp receptacle:

  • The kiln has a standard plug so I'm guessing the previous owner switched it but I don't think the temperature is getting high enough and I wondered if that could be caused by it plugging into a 15A circuit/receptacle. – Val F Nov 26 '16 at 21:38
  • I don't think the 15 amp circuit would be causing your temp. problem. If the device were trying to pull more than the circuit could deliver you would likely blow a fuse or trip a breaker. – Jimmy Fix-it Nov 26 '16 at 22:29
  • Are you using an ext cord? What gauge? How long? If it's not getting hot enough I would suspect either voltage drop or one of multiple heating elements burned out. Although the amount of heat being produced being plugged in is no more than a hair dryer. To produce the high temp like kilns do the kiln would have to build up heat over time and keep it all inside. – Tyson Nov 27 '16 at 1:22
