# Calculate How Many Amps On A Circuit Board Handle

By | January 7, 2023

For most homeowners and do-it-yourselfers, the thought of calculating how many amps a circuit board can handle may seem like a daunting task. But the truth is that understanding and mastering this skill is essential for anyone who wants to safely and successfully work on their own home's electrical system. After all, proper wiring and electricity usage are equally important for both safety and efficiency.

The process of calculating the number of amps that a circuit board can handle begins with understanding the basic anatomy of an electrical circuit. In simple terms, a circuit is a closed loop of wiring that has a power source (like a battery or outlet) and various devices connected to it. When electricity flows through the circuit, it’s routed to the devices via the individual wires.

The amp rating of a circuit board is typically determined by the size of the circuit breaker. This can be found on the back side of the circuit breaker box. The size of the breaker is usually measured in amps—for example, a 15-amp breaker will be designated as a “15A” circuit breaker. This number is the maximum amount of current (measured in amps) that the circuit can safely handle before it trips and shuts off the power.

In order to determine how many amps the circuit board can handle, it’s important to calculate the total wattage of all the devices connected to the circuit. To do this, simply add up the wattage ratings of all the devices connected to the circuit and then divide the total by the voltage of the circuit. For example, if you have five 100W light bulbs connected to a circuit running at 110V, the total wattage for the circuit would be 500W (5 x 100W). Dividing 500W by 110V gives you an amp rating of 4.54A.

It’s also important to note that the total wattage should never exceed the amp rating of the circuit breaker. For example, if the circuit breaker is rated at 15A, the wattage of all devices connected to the circuit should be limited to 1,650W (15A x 110V). Exceeding this limit can cause the circuit breaker to trip and could result in a fire hazard.

Calculating how many amps a circuit board can handle may seem like a complex task, but following the steps outlined above can help ensure that you’re always using your home’s electrical system properly and safely. By taking the time to learn about the basics of electricity and the proper calculations involved, you can help protect yourself and your family from the potential dangers of electricity.
