What is the standard to select circuit breaker?

Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.

What size amp circuit breaker should be used for a geyser?

Depends on how many amps it pulls and the size of the wire in the circuit.


What size circut breaker for 10-2 wire?

A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.


What size wire and breaker do you need for a 5000 watt garage heater?

Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 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.


Should 25 amps breaker be replaced by 20 amps?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.


Which circuit breaker to use for the plugs and geysers?

It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.


What size Mini circuit breaker is the same as a 13 amp fuse?

13 amp breaker. A fuse and circuit breaker perform the exact same function so they should be the exact same size. They protect the wiring within a circuit from overheating and catching on fire. A 13 amp breaker is a superior product that has a good chance of operating between 13 and 13½ amps, while a fuse might not blow until the current reaches 15 amps.
