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.

∙ 7y agoOn a single phase split secondary distribution panel you will never get 240 volts from a single breaker. A single breaker only has the capacity output of 120 volts. It takes two adjacent breakers to give an output of 240 volts. The two pole breaker takes up two slots on the panel board. From either of these two breaker outputs to ground or neutral you will receive a reading of 120 volts. To read the 240 volts the reading has to be taken across both of the breakers output.
Test one side of the breaker to neutral, it should read 120 volts. Test the other half of the breaker to neutral it should read 120 volts. Now take the reading between the two output legs of the breaker. This reading should be 240 volts. If you do not get all three readings then the breaker is faulty and should be replaced.

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 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 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.
What size amp circuit breaker should be used for a well?
Usually 30 Amp 240 volts, but there will be a spec on the well pump.
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.

What kind of wire do you use for 120 volts and what amp breaker do you use?
#12/2wground & a 20 amp breaker should be enough for lights,receptales.

How many volts should your fuel pump be getting?
12 volts DC.
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 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 size breaker should be used for a 3.6 kW oven?
3000 / 240 = Amps. You de-rate a breaker by 20 % for continuous load like an oven. You could get by with a 20 Amp breaker and 12 AWG wire. However, I would recommend 30 Amps and 10 AWG for an oven for the long run.
How do you calculate amp of circuit breaker to use on a 4800w oven?
Ovens typically run at 240 volts which will be a two pole breaker in your panel. Watts = volts x amps. 4800 / 240 = 20 amps. If by chance you are using 120 volts then double it to 40 amps. All wiring must conform to size of breaker used.
Will a 4500 watt element work at all or just trip a 20amp breaker?
A 4500 watt element will work on a 20 amp breaker if it operates at 220 volts or less. It will simply trip the breaker if the load is greater than 20 amps at 220 volts.
