It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.
Remove the two twenty amp breakers from the regular size slot and install two mini amp breakers. A mini amp breaker has two breakers per regular size slot.
Yes. A twenty amp circuit just means the breaker (fuse) will kick in if you draw more then 20 amps, but its fine to use at less amperage.
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
Replace the 30 Amp Breaker with a 15 Amp breaker.
A 50 amp breaker is an overcurent device.
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
The Siemens 200 amp main breaker in an electrical panel is responsible for protecting the electrical system from overloads and short circuits by disconnecting power when necessary.
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
NO!
No, you should not install a 30 amp circuit breaker to a machine which normally requires a 20 amp supply. The circuit breaker is protecting the wire to the machine. That wire is likely only rated for 20 amps, (# 12 awg). Therefore, a 30 amp breaker could allow too much current to go through the wiring to the machine and cause the wire to burn down. Replace the 3 phase 20 amp breaker with the same amperage breaker.
The breaker commonly used for ranges is a 40 amp. This size is used to cover the total wattage of the range. If for some reason all of the top elements and the oven were in use at the same time then the amperage drawn would be just under the trip setting of the breaker. If this same scenario were played out on the range with a 30 amp breaker supplying the power it would trip the breaker.
