The answer to 'generator installation tripping breaker' is that a tripping breaker is a common issue when installing a new generator, and there are several possible causes. The most likely reasons are an electrical overload, a short circuit, or a ground fault in the generator or its wiring. Symptoms may include the breaker repeatedly tripping, power fluctuations, or the generator not starting at all.
To troubleshoot, first check the generator's wattage capacity and ensure it is not exceeding the electrical panel's rating. Inspect all wiring connections for any damage or loose fittings. You may also need to adjust the generator's voltage regulator or circuit breaker settings. If the issue persists, it's best to call in a licensed electrician to diagnose and resolve the problem properly and safely.
