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.
What else can I help you with?
Is 30 amp double pole breaker ok for 4800 watt wall heater?
Yes, a 30 amp double pole breaker would be suitable for a 4800 watt wall heater. Since watts equals volts multiplied by amps, this wall heater on a 240-volt circuit would draw 20 amps (4800 watts/240 volts), which is less than the 30 amp capacity of the 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?
To check if you have 240 volts on a 30 amp two pole breaker, you can use a digital multimeter set to measure voltage. Turn off the breaker, then test between the two breaker terminals and ground. If you read around 240 volts, it indicates that the breaker is providing the right voltage. If not, there may be an issue with the breaker or the wiring.
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.
What size breaker to use for a hand dryer its 120v 20amps?
For a 120V hand dryer with a rating of 20 amps, use a 20 amp breaker to match the device's ampacity and prevent potential overloading or overheating issues.
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.
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 volts can b drawn off a 240 volt breaker?
240 volts maximum.
What should the reading at the light switch be when the switch and the light fixture is removed. I had a dimmer switch on that light it went out I checked the volts at the switch they were about 14?
On the "hot"wire that comes from the breaker panel the voltage should be from 115 to 120 volts. This is taken from the "hot" wire to either the neutral or the ground wire. If its not then you have a breaker problem or you are on the wrong scale of the test meter.
What are the differences between a double pole and a single pole breaker?
A double pole breaker controls two hot wires and provides 240 volts of power, while a single pole breaker controls one hot wire and provides 120 volts of power.
How many watts will a 60 amp 2pole breaker handle?
A 60 amp 2-pole breaker can handle up to 14,400 watts (60 amps x 240 volts). This is because a 2-pole breaker provides 240 volts, which is the typical voltage for larger appliances and machinery.
