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.
On 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.
On a 15 amp breaker, you can draw up to 120 volts in a standard residential circuit. The voltage remains constant at 120 volts, but the amperage capacity is what is limited by the 15 amp breaker.
This could indicate a voltage drop in the circuit due to poor connections, damaged wiring, or a faulty breaker. Check for loose connections, damaged wires, or a malfunctioning breaker as possible causes of the voltage drop. It's important to address this issue promptly to ensure safety and proper electrical function.
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.
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.
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.
On a 15 amp breaker, you can draw up to 120 volts in a standard residential circuit. The voltage remains constant at 120 volts, but the amperage capacity is what is limited by the 15 amp breaker.
#12/2wground & a 20 amp breaker should be enough for lights,receptales.

12 volts DC.
240 volts maximum.
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.
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.
lol. 12v in, only 6 out. looks like your switch is eating 6 volts. Get that out of there. then the other volt drops should come into check. You should only have a .5v total volt drop in the whole circuit; after that problems start to pop up.

The equation that you are looking for is I = W/E. Amps = Watts / Volts.
Yes, it can.
