Why Do Circuit Breaker Trip During Lightning

By | September 24, 2022



Lightning storms are one of nature’s most powerful forces, and they often leave homeowners and electricians scrambling to deal with the aftermath. Whether it’s a power outage or a damaged appliance, lightning can cause serious damage to your home’s electrical system. One of the most important systems in place to protect you from the harmful effects of lightning is the circuit breaker. When lightning strikes, the circuit breaker trips, cutting off the flow of electricity and preventing further damage. But why does the circuit breaker trip during lightning?

The first line of defense against lightning damage is the circuit breaker. A circuit breaker is a safety device that guards your home against dangerous electrical surges. It works like a switch that can be manually triggered to shut off the electricity in your house if too much current flows through the system. When lightning strikes, the surge of electricity can overload the circuits in your home, causing them to short-circuit and potentially start a fire. The circuit breaker trips as soon as it detects this overload and prevents further damage by breaking the flow of electricity.

It’s important to note that circuit breakers don’t actually protect your home from a direct lightning strike. Instead, they protect your home from what is known as a side flash, which is an electrical surge that jumps from the lightning strike to your electrical system. This side flash is what causes the circuit breaker to trip and shut down power in your home.

There are several components that work together to make sure your circuit breaker trips during lightning. First, your home must have an effective grounding system. This includes grounding rods around the home, as well as bonding or connecting metal components of your electrical system. This ensures that any current from the lightning will be diverted away from your home, rather than coursing through the wiring and potentially damaging your appliances.

Next, your circuit breaker must be set to the correct surge rating for your area. Lightning surges can be unpredictable, so it’s important to make sure your circuit breaker is rated to handle the amount of electricity expected in your location. Finally, your home’s wiring should not have any defects or worn out insulation that could cause sparks or short-circuits when hit by a lightning strike.

By taking these steps, you can ensure that your circuit breaker will trip if lightning strikes nearby. This will prevent any further damage to your home and its electrical system. With a little preparation, you can rest easy knowing that your home is protected from the effects of lightning.
