Electrical Wiring in the Home/upgrading a 15 amp 220 outlet to 60 amps



I need to plug in a kiln.  Itís specs follow.  I have a 15 amp 220 outlet that Iíd like to upgrade to 60 amps.  It is about a foot away from the breaker box in my garage.  It is the correct NEMA receptacle configuration.   I want to verify, I just need to replace the breaker with a 60 amp one and upgrade the wire size to 6 gauge, correct?

I have 150 amps coming into the house.  Should I turn off the breakers for the other 220 v circuits (50 amp range and 30 amp dryer) while I fire my kiln?

recommended electrical specifications listed in the owners manual:
Skutt KM-1027 kiln
240    Volts
48   Amps
11520   Watts
6    Copper Wire Size
60   Fuse or Breaker Size
6-50   NEMA Receptacle Configuration


ANSWER: Roselle,

A 15 amp 220 Receptacle will not have the same NEMA # as a 60 for the simple reason the plug configurations are different as well as the amperage capacity so you will be upgrading everything including the size of the box in order to handle the much larger receptacle and bigger wires.

As far as turning off other breakers when you use the kiln, I don't know what other electrical loads you have in your home that are significant and could pose a potential problem. Your service will still have a 100 amps left for everything else when the kiln is on so I doubt you would have a problem. The worst that could happen is you trip the main circuit breaker. Again I doubt that will happen unless your house uses all elecric for heat and you have an electric dryer, and electric hot water heater.

I should have been more specific.  The breaker is 15 amp/220.  The receptacle says 250V 50Amp on it, and 6-50R.  I donít know what the R means.  I think I just need to upgrade the wire to 6 gauge and replace the breaker with a 60 amp one.  It seems straightforward.  I just wanted to check because its my first time doing it.

Thanks for the feedback on if I should turn off the other breakers.  I have teenagers in the house that may space on not being able to use all the appliances.  It sounds like I can take a chance on it if the worst that would happen would be that the main circuit breaker would trip.

I have a permit and it will be inspected.

I appreciate your feedback,


Not a problem. The "R" refers to "receptacle" which is what it is. "p" would mean "plug".

Assuming the existing box is big enough for the new # 6 wires you would only have to upgrade the wire and the breaker. Make sure the plug is properly grounded to the box,it may be fine already just saying to check it.

Happy Kilning !

"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
