Small Appliance Repair Questions? Ask a Technician ASAP
Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.
1) What is the wattage of the cooker?
2) Is the cooker running simultaneously with any other connected loads on the same circuit?
3) How many amps is the circuit? 15 or 20 amps?
Thanks for the replies.
1) Most cooktop small appliances are 120 volts. How many volts is the cooker rated for 120 or 240 volts?
2) A 10.8kW appliance is a 240 volt supply. Applying Watts Law where P = I x E, solve for I (Current). I = P/E = 10,800 watts divided by 240 volts = 45 amps. Thus a 30 amp breaker will always trip since the circuit is overloaded.
Is the cooker 240 or 208 or 120 volts?
1) The branch circuit over current protection device is undersized. Do the math by applying Watts Law. P = I x E. Solve for I
I = P/E = 10,800 watts divided by 208 volts = 51 amps. No way will a 30 amp OCPD protect a 51 amp load. The breaker will trip every time, especially if a continuous 3 hour or more load.
