Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?

No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.

∙ 14y agoNever upgrade the circuit breaker's amperage unless you have first upgraded the circuit. A 20-amp breaker will pop before a 12-AWG wire will melt. A 25-amp breaker cannot be relied upon to protect that same 12-AWG circuit.

What circuit is a microwave?
A dedicated 20 Amp circuit wired with 12/2 wiring an a 20 amp breaker.
Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
Can a 3 phase 220 volt machine that usually plugs into a line with a twenty amp breaker can a thirty amp breaker be used instead?
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.
Does square D make a circuit breaker with a 15 amp and 20 amp breaker in the same breaker?
No tandem breakers are of the same value.
What is the capacity in amperes 20 amp circuit breaker supplying a continuous load?
For a continuous load the circuit breaker is set 25% higher than the load current. So a 20-amp breaker is used with a continuous 16-amp load.

New shop 20 amp circuit 32 amp fixture how many fixtures can be put on circuit?
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.

Is there any disadvantage of selecting over rated circuit breaker?
If i understand you correctly, yes there certainly can be. If you replace, say a 10 amp breaker with a 20 amp. you are losing the safety factor - the whole purpose of the breaker to begin with. Always replace a breaker with the exact same amperage rating!

How many 1.2 amp lights can a 20 amp breaker hold?
No more than 13 maximum on a 20 amp circuit.
Can a 20 amp breaker be replaced with a 15 amp?
Yes, provided that you don't really need 20 A on the circuit.
How many ampacity rating do a circuit breaker need for the general purpose circuit?
Usually a 15 or 20 amp breaker is sufficient
What size amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
If the fault was on the 20 amp branch circuit, the branch circuit breaker should have tripped, not the main breaker. Call a qualified electrician to check out your wiring.
