30 amp breaker with #10 gauge copper wire
LRA (locked rotor amps) is not used to calculate the breaker size. Breaker's are used to protect the size of the conductor that is connected to it. Motor calculations are based on the motor's FLA (full load amps).Conductor size is 125% of the motor's FLA.Breaker size is 250% of the motor's FLA.This is the only occasion when the breaker is sized larger that the conductors maximum amperage rating. This is due to the motor drawing up to 300 to 600% of its FLA when starting.If you state the motor's wattage, voltage or amperage this calculation can be calculated here.
A 6-gauge wire should be used with a 60 amp breaker.
For a 25 amp breaker, a wire size of at least 10 gauge should be used to safely handle the current.
A 40-50 amp breaker is typically used for an electric range.
For a 30 amp breaker, a wire size of at least 10 gauge should be used to ensure safe and proper electrical connections.
This is determined by the size motor and the amount of amps the motor draws, be on the safe side and consult the owners manual or an Electrician. <<>> The sizing of the breaker and feeder wire is based on the amperage of the compressor. Look on the name plate and find the amperage. The amperage on the nameplate then has to be multiplied by the motors full load amperage and that value is used for the wire size. Because the load is a motor the FLA is again multiplied by 250% to size the breaker. This takes into allowance the high starting current of a motor from 0 to 100% RPM.
50 amp breaker wired with AWG # 6 wire.
For a 100 amp breaker, a wire size of 2 AWG (American Wire Gauge) should be used to ensure proper electrical safety and performance.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
For a 50 amp breaker, a wire size of at least 6 AWG (American Wire Gauge) should be used to safely handle the electrical load.
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
For a standard refrigerator, a 15-20 amp circuit breaker is typically recommended.
