Distribution Boxes: Types and Functions
These power distribution boxes come in various shapes, sizes, and designs, which can be customized based on specific needs. They can vary in
Read MoreHome / What size circuit breaker should the secondary distribution box have
To determine the size of the breaker, you can use the following formula: Total Load (amps) = Number of Circuits x Circuit Amps For example, if you have a subpanel with five 20-amp circuits, the total load would be 100 amps (5 circuits x 20 amps). Choosing the right size and setup for your distribution box keeps your electrical system safe and working well. You lower the chance of circuits getting too hot or overloaded when you pick the right box for your needs. Just enter your load, voltage, and power factor (if applicable), and let us handle the rest! How to Select The Right Circuit Breaker. The 125% rule for continuous loads is critical – a breaker must be rated 25% higher than the continuous load current.
