Best Answer

The electrical current requirements of a wall oven can vary, depending on the heating elements used by the manufacturer.

To determine the current use, refer to either the operators manual, or the service tag.

The service tag may list the power consumption in Watts, in which case you'll need to convert the watts to amps using the following formula:

Amps = Watts/Volts

Once you've determined the current draw in Amps, OVER-rate the breaker by 20%. For example, if you calculate that the oven draws exactly 20 amps, over-rate that to 24 amps, then use the next larger size breaker and wire that is appropriate to the breaker; typically that would mean a 10 AWG wire and 30 Amp breaker.

BUT!!! If you have any questions, contact a licensed electrical professional.

There is a rating plate on the dishwasher that will tell you how much current it draws. A typical breaker would be 20 amps with 12 AWG wire.

How are Branch circuit protected?

Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker


When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.


What size wire and circuit breaker is needed for an electric oven 4 wires with rated load of 34.9 amps 220v that is about 100 foot run from the electrical panel?

That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.


What size breaker should be used for a double oven?

50 amp breaker wired with AWG # 6 wire.


What size amp circuit breaker should be used for a home entertainment system?

You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.


What size circuit breaker should be used for dishwasher and disposal?

A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.


What size amp circuit breaker should be used for a geyser?

Depends on how many amps it pulls and the size of the wire in the circuit.


What size amp circuit breaker should be used for a pool light?

The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.


What size amp circuit breaker should be used for 110 outlet?

The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.


Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?

A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.


What size in amperage circuit breaker should be used for a pool pump?

The sizing of the circuit breaker and hence the wire size to feed the pump are all dependant upon the amperage of the pump. This question can not be answered without that information.


What is the standard to select circuit breaker?

Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
