Learn How To Calculate Safe Electrical Load Capacities

November 03, 2022

We all have plenty of electronics in our homes, but if you try to use too much at once, you risk blowing a fuse and causing a power outage. To avoid such mishaps, it’s a good idea to learn how to calculate safe electrical load capacities.

Different Circuits

Many of the electronics that we use in our homes require their own circuits to operate. Appliances and devices like dishwashers, microwaves, refrigerators, air conditioners, furnaces, and ovens require different size circuits. A device operating over the total capacity may make the circuit short out and lose power or break down.

Calculating Capacity

When learning how to calculate safe electrical load capacities, there’s a very helpful equation that works as a solid foundation. Ohm’s Law tells us that wattage is equal to amperage multiplied by volts. You can generally find the amperage, wattage, or circuit voltage of any device on the device itself or packaging, but if you only have some of the information, you can generally figure it out by using the equation.

For example, 25 amps x 120 volts = 3,000 watts. If you know the amps and wattage, you can figure out the capacity size by working backward.

Utilizing Your Electrical Service

Different homes have various sizes of electrical services, which helps determine what circuit sizes you can use at once and how you can minimize the chances of breaking a circuit or causing a power outage. There are several ways to check the size of your electrical service so you know the window in which you can operate. If you’re still unsure, contact an electrician who can help provide plans and services to expand your service size for the future.
