In North America a 40 amp breaker is used on 240 volts. W = A x V = 40 x 240 = 9600 watts. That is the maximum that can be drawn from the circuit but usually only one or two burners or the oven are ever used at one time reducing the wattage load. On the back of the range there is a nameplate with all of the specification of your unit.

Could you get the watts for certain sockets?
Yes, very easily. Receptacles and other electrical devices are rated in amperage that the device can use or handle. Take that amperage and multiply it by the voltage that the device is rated for. The answer will be in watts. This wattage will be the maximum that is allowed from the receptacle or any other device.
What does LRA mean in electrical terms?
Locked rotor amperage is the amperage the motor draws when the voltage is first applied to the motor and the rotor has not started to turn. This amperage is usually up to 300% of the motors running amperage. Once the rotor starts to turn the motor generates a back EMF (electro motive force) that opposes the high inrush current. This back EMF drives the amperage down until the motor gets up to its rated speed at which time the motor amperage will be at its run amperage.
How does the fuse wire save your electrical appliances?
The fuse wire is rated for a specific amount of amperage. If the amperage exceeds that rating, the fuse wire will quickly melt. The current flow in the circuit is interrupted, thereby protecting the appliance from an overload condition.
What is the calculated amperage for an electric range rated at 16 kw?
16 kW at 240 volts runs at 16000/240 amps, or 67 amps.
Which insulated electrical wires match specific Amp loads?
All electrical wires are rated for specific amperage's. This is why conductors are matched to the load current so that a smaller size wire in not used on a heavy load current.
What amp rated cord do you need in relations to watts?
If you know the wattage of a device and would like to know the amperage the device draws use the following formula. I = W/E, Amps = Watts/Volts. Once you know the amperage the wire is sized accordingly. For the electrical trade #14 is rated at 15 amps and #12 is rated at 20 amps.For smaller size wires see Sources and Related linksbelow
What is FLA in electrical terms?
FLA = full load amps <<>> It is a term that is associated with motors. It is the amperage of the motor when it operates at its full rated horsepower under load.
If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?
There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.
Can you use a 36 watt fuse for a 40 watt fluorescent bulb?
Fuses are not rated in wattage, they are rated in amperage and voltage.
Whet does 4-8 ohms mean?
this is range of 4 ohms resistance in an electrical device. Ohms is a measure of resistance in electrical qualities. Circuits and devices are rated , or measured for there resistance in ohms to meet a designed electrical need. Is this related to a speaker?
What size of wire you need to install a cook top?
The sizing of wire is dependant on what the amperage or wattage of the range is. Most new homes are pre-wired for a standard size range. The wiring is #8 with a insulation factor of 90 degree C and rated for 40 amps. This feeder is protected by a 40 amp breaker.If the amperage or wattage is larger than this, then a larger conductor must be installed. Use this equation if you need to change wattage into amperage. I = W/E, Amps = Watts/Volts. If the range is in kilowatts multiply the kilowatt number by 1000 to change it to watts to use in the equation.
What is an ordinary electrical outlet rated at?
In North America an ordinary electrical receptacle is rated at 15 amps.
