If you have to ask, call an electrician.

Seriously, if you poke around inside a live electrical panel where the breakers are, you have the potential not only for a fatal electric shock, but also for an arc blast. To do this safely requires proper protective equipment (blast shield, gloves, boots) as well as properly rated industrial voltmeter with the right kind of input protection circuitry. If you've got the right equipment and the safety training to know how to avoid killing yourself when you use it, then you'll know how to measure the voltage (probe the output of the breaker against ground and read the number on your meter).

How do I know if I have a 30 amp breaker at my house to plug a trailer into?

If it is a 30 amp breaker then it is a 240 volt outlet.


What size breaker for a 1500 watt 120 volt heater?

To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.


How many volts can you draw off of a 15amp breaker?

It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.


Can you use a 220 breaker in place of 110 breaker on 110 service?

Answer for USA, Canada and countries running a 60 Hz supply service.Breakers are rated in amperage and by the amount of poles that they have. Your classification of a 220 breaker is described in electrical terminology as a two pole breaker.Choosing the amperage of the two pole breaker depends upon the 220 volt load that it feeds.Two pole breakers for 220 volt loads.Single pole breakers for 120 volt loads.If the service is only 120 volt then every other bus bar in the panel will be energized. If the panel is a 120/240, then every bus bar in the panel will be energized.This is how and why a 240 volt load requires a two pole breaker.To the answer, yes you an use a two pole breaker in a 120 volt service but only one side of the breaker will have voltage on it depending on where it is situated in the panel board.


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

For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.

How do you test a 220 volt breaker?

You will need a multimeter to check a 220 volt breaker. You should unplug appliances that go to that particular breaker. Use the multimeter at the breaker to check the voltage. If it shows 220, then the breaker is okay. If it doesn't, then the breaker is no good.


What is the appropriate size of a breaker needed for a 240-volt circuit that requires a 50 amp breaker?

For a 240-volt circuit that requires a 50 amp breaker, the appropriate size of the breaker needed is 50 amps.


Can you connect 110 volt circuit breaker to 220 volt circuit?

No, you cannot directly connect a 110-volt circuit breaker to a 220-volt circuit. Circuit breakers are designed for specific voltage ratings, and using a 110-volt breaker on a 220-volt circuit can lead to improper operation, potential equipment damage, or safety hazards. If you need to work with a 220-volt circuit, you should use a breaker rated for that voltage. Always follow electrical codes and consult a qualified electrician for such modifications.


What is the Largest amperage single phase 120 volt breaker made?

6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.


How volts comes from a 20amps breaker?

On most residential circuit breaker boxes in North America, each individual breaker represents one 120-volt circuit. Two breakers ganged together represent a 240-volt circuit.

How many volts can you draw off of a 15amp breaker?

It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.


How do you convert 208 volt amps to 480 volt amps?

Add another leg of 120 to a three pole breaker.


What is the difference between a single pole and a double pole breaker?

A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
