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.

Is 30 amp double pole breaker ok for 4800 watt wall heater?
Yes. watts / volts = amps. 4800/240=20amps.
What size breaker to use for a hand dryer its 120v 20amps?
Single pole 20 amp breaker.
What ohm value or what combenation of resistors are needed to draw 20amps at 120v?
ohms = volts/amperes 6 ohms = 120 volts / 20 amperes
How can you check if you have 240 volts on a 30 amp two pole breaker?
A simple voltage tester. Just check both sides of the breaker where the wire comes in
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 many 120 watt bulbs could run on a 20amps breaker?
In this case Watts = Volts x Amps. If we assume 120 volts there is 1 Amp per bulb. Theoretically that would be 20 bulbs. However, for continuous operation you should be at only 80% of the load current or 16 Amps. So the answer is either 20 or 16 depending on if this is a math problem or a quiz for an electrician.
Why am I only getting 120 volts from a 30 amp breaker that should be feeding 220 volts?
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
How many 110 volts can be ran on one breaker?
One breaker in the North American electrical system will supply 110 volts. Two adjacent tied breakers will produce 220 volts.
How much voltage comes into a breaker box?
In the United States, the normal house that is being built has 220 volts alternating current to legs each one carring 110 volts ac to ground.
You are getting 110 volts after the circuit breaker but only 50 volts at breaker why?
you have a magic power-generating CB find out how it works and you should make a fortune.
How many volts can b drawn off a 240 volt breaker?
240 volts maximum.
How many pole breaker for air condition?
If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.
