I'd try to stay about 16 amps to prevent the breaker from nuisance tripping.

That is as many as 32 - 60 watt incandescent (normal) lights or 83 - 23 watt CFLs. In practical terms it is hard to overload a single circuit with lights or other small loads (just about anything using a receptacle except the obvious AC unit or vacuum cleaner).

The general rule of thumb is to size a breaker at 150% of the continuous load or 125% of the non-continuous load. For a 20 amp breaker, this means it can handle a maximum of 16 amps for a continuous load and 20 amps for a non-continuous load, such as a lightning load.

What is type of breaker for 41 amp's?

For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.


If an electrician have a circuit that pulls a load of 10 amps what size breaker must that circuit be protected by?

For a circuit with a load of 10 amps, a breaker of 15 amps should be used for adequate protection. It is important to choose a breaker size that is slightly higher than the load to prevent frequent tripping and ensure safety.


What size circuit breaker is used for a 10000 watt single phase cooler with 240 volts?

The equation for amperage is Amps = Watts/Volts = 10000/240 = 41.6 amps. It is not stated if this is a motor load or not. If it is a motor load then the feeder has to be rated at 125% x 41.6 = 52 amp wire. Also if it is a motor load then the breaker will have to be 250% x 41.6 = 104 amps. A 100 amp breaker will work and still be within the electrical code ruling. Otherwise for 41.6 amps a 50 amp breaker will be sufficient.


What size breaker do you need for a well pump?

A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.


The total load 75 amps is continuous what size breaker is required?

For a continuous load of 75 amps, it is recommended to use a breaker that is rated at least 125% of the continuous load, as per the NEC guidelines. Therefore, a 94-amp breaker would be suitable for this application.

KA stands for kilo-amps, or thousands of amps. Thus a 2KA breaker means it will trip when the load exceeds 2,000 amps.

What is the effect of using a current trasformer CT meant for 630A breaker maximum load for 1200A breaker maximum load in relation to current measured and protection relays?

No good idea. The CT may not function well at a load beyond 630 amps. It may even fail at higher load (than 630 amps)


What breaker for 17.3 amps?

I would suggest a 20 amp breaker. * Added - I would suggest a 25 amp breaker. A slight surge, depending upon what equipment is the source of the 17.3 amp load, should not result in circuit breaker opening. <<>> In North America, the electrical code only allows circuit loading up to 80% on a continuous load. A 20 amp breaker can be legally loaded to 16 amps. A 25 amp breaker can be legally loaded to 20 amps.


Can you put 10-3 UF cable on a 50 amp circuit breaker?

A #10 copper conductor with an insulation rating of 90 degrees C is rated at 30 amps. The only time that a breaker larger that the load maximum capacity can used is in motor connections. A breaker can be used sized at 250% of the motor's full load amperage. In this case a 50 amp breaker can be used on a #10 conductor if the motor's full load amps falls within the amperage's of 20 - 22 amps.


The Function Of A Twenty Amp Breaker?

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.
