LRA is 134 AMPS. what size breaker should be used?
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.
What size amp circuit breaker should be used for a air compressor?
The size of the amp circuit breaker needed for an air compressor depends on the motor's wattage and starting current. As a general guideline, a 20-amp circuit breaker is commonly used for smaller air compressors, but it's best to consult the compressor's manual or an electrician to determine the correct size for your specific model.
What size breaker should be used for a double oven?
50 amp breaker wired with AWG # 6 wire.
What size amp circuit breaker should be used for 110 outlet?
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.
What size circuit breaker should be used on 125 feet of 4 AWG power feed?
The circuit breaker is used to protect the conductor that is connected to it from an overload condition. On a motor load the breaker has to be sized 250% of the motors full load amperage. Some circuits can be only loaded to 80% capacity and this is governed by the sizing of the breaker. Without knowing what the load amperage is, this question can not be answered.
What size circuit breaker should be used for dishwasher and disposal?
A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.
What size breaker is used for a 300 horsepower motor?
A breaker is based on the amount of current that the motor draws. This amperage should be taken off of the motors nameplate. In motors of a specific horsepower the amperage is proportional to the voltage the motor uses. Without the motors voltage this question can not be answered.
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.
Is a one half HP motor sufficient to run a dehumidifier with 15 Amps and 115 Volts?
A 1/2 HP 115volt motor draws 9.8 amps. This is a nominal book amperage for a 1/2 HP motor, check the nameplate for an accurate value. A breaker, to protect this size motor, has to be rated at 250% of the motors full load amps. In this case a 25 amp breaker in needed. If using the actual nameplate amperage, multiply it by 250% to find the size of the breaker to use. If the motor used 230 volts as a supply a two pole 15 amp breaker would work.
Breaker trips after running pool motor about 8 hours the timer and receptacle was changed but I noticed a little bit of rust on the plug to the pool motor should that be changed?
YES ALL CONECTIONS MUST BE SQUEAKY CLEAN AND THE PROPER SIZE POWER CORD MUST BE USED..
What size breaker should be used for a TNIA-10 wire?
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
