The formula to calculate the proper amperage size of a circuit breaker is:
\[ A = \frac{P}{V} \]
Where:
A circuit breaker is a device that stops the flow of current in an electrical circuit if a certain current level is exceeded. For example, if a circuit breaker is rated for a current of 1000 amps, and the current reaches 1005, then the circuit breaker should cut off all current to the system.
Let's assume the following values:
Using the formula:
\[ A = \frac{4800}{240} = 20 \text{ amps} \]
The Circuit Breaker Size (A) is 20 amps.
