Seeing that you are from Illinois you should know that in North America there are no 10 amp distribution panel breakers.

What is the continuous current draw on a 20 amp circuit breaker?

Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.


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.

The headlight circuit breaker is intergrated with the headlight switch.


What circuit breaker to install for 10 amp 250 volt circuit?

You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.


Should 25 amps breaker be replaced by 20 amps?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.


How many ampacity rating do a circuit breaker need for the general purpose circuit?

Usually a 15 or 20 amp breaker is sufficient


The Function Of A Twenty Amp Breaker?

It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.


What circuit is a microwave?

A dedicated 20 Amp circuit wired with 12/2 wiring an a 20 amp breaker.


Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?

No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.


Do you have a 15 0r 20 amp circuit?

Go to your distribution panel and shut off the breaker that you think is the circuit in question. If the circuit becomes de-energized then the breaker you just turned off feeds that circuit. Look on the handle of the breaker and the number you see is the amperage of that circuit. <<>> Determination of a 15 or 20 Ampere circuit is normally indicated by a combination of a 20A breaker and a 20A dedicated outlet. A 15A circuit normally has multiple outlets; not typical in a 20A circuit.


Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?

No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.


Can you use a 20 amp circuit breaker for an electric dryer?

If you are referring to a cloths dryer, the answer depends on the requirements of the dryer. Most dryers require AWG#10 wire with a 30 amp fuse. If the wiring is AWG#12 then use a 20 amp breaker but never use it on AWG#10 which requires a 30 amp breaker. If you are referring to a hair dryer then yes a 20 amp breaker is fine.
