Short Circuit Does Not Trip Breaker

By | January 10, 2023



No one likes dealing with the aftermath of a short circuit, whether it's in the home or in an industrial setting. Short circuits can cause expensive damage and potentially put people at risk if not dealt with quickly. Fortunately, the installation of a breaker box in the home or business is designed to protect against the risk of a short circuit. But what happens when a short circuit occurs and the breaker doesn't trip?

When a short circuit occurs, the current flow is rapid and intense, and can quickly overload the circuits. In these cases, the breaker should respond by tripping and cutting off power to the circuit to avoid any further damage. However, if your breaker does not trip, then the wiring is likely defective and could be a potential fire hazard.

One of the most common causes of a breaker not tripping is a faulty connection. Breakers are designed to trip when they detect an excessive amperage, but if the connection is loose, this detection process can be disabled, allowing the current to run unchecked. This can quickly cause an overload, resulting in a situation known as “arcing”, where electricity jumps from one wire to another, causing a spark and potential for fire.

The best way to prevent this is to have a qualified electrician inspect the breaker box, wiring, and connections for any signs of wear and tear, loose connections, or any other defects. This can be done as part of regular maintenance or before installing a new breaker.

If your breaker does not trip, there could also be a problem with the breaker itself. Breakers are designed to trip when they sense an overload, so if the breaker is faulty or not installed correctly it may be unable to do its job. If this is the case, it's essential to have a professional electrician inspect and replace the breaker as soon as possible.

Finally, if your breaker still doesn't trip, it could be due to an issue with the circuit itself. If the circuit is overloaded, the breaker may fail to trip even when the current is too high. This can be a dangerous situation and should be inspected by a professional electrician immediately.

Dealing with a short circuit is never fun, but if your breaker does not trip, it's important to take the necessary steps to ensure the safety of your home or business. Have a professional inspect all wiring and breaker boxes to identify any potential hazards, and replace any defective breakers or wiring to prevent further issues. Taking the time to understand why a short circuit does not trip a breaker can help prevent serious damage and keep you and your family safe.
