To make a load calculation, you'd need the voltage (volts) and the current (amps) in the distribution line. That would give you the power consumption (watts), and you could find that by multiplying volts times amps. P = I x E [Power equals current times voltage.]

To calculate the load on a breaker box, add up the amperage ratings of all the individual circuits connected to the box. Ensure that the total does not exceed the capacity of the main breaker in the box. This can help prevent overloading and ensure the safe operation of the electrical system.

On new installations, load calculations are based on square footage of the building. The second calculation is based on the type of equipment that is to be connected. If you want to measure the load on an existing breaker box, find the current draw coming into the box times the highest voltage coming into the breaker box and multiply them together for the total wattage of the breaker box at that moment in time.

Any continuous load shouldn't exceed the rated kV.A or your generator.

Can I add a circuit breaker wired in parrell to a current breaker to reduce the load on the breaker?

Adding a circuit breaker in parallel with an existing breaker may not reduce the load on the breaker. It is important to size the breaker according to the electrical requirements of the circuit and not to bypass the original breaker. Consult with a qualified electrician to ensure the proper installation and function of the circuit breaker.


Duplex receptacle circuit given 15 amp breaker 225 amp load?

A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.


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.


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.


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.

How do you calculate breaker capacity of 10 hp three phase induction motor?

The first thing you have to do is find the full load amps of the motor. The wire size feeding the motor has to be 125% of the full load current. The breaker is usually 250% of the full load current. If the voltage and amperage had been added to the question the exact breaker size could have been calculated.

How is a Load applied to a ac generator?

The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
