The answer to 'generator installation tripping breaker' is that a tripped breaker when using a generator is often caused by an overload or short circuit. This can happen if the generator is not properly sized for the electrical load, or if there is a problem with the wiring or connected appliances.
Some common causes include trying to power too many high-wattage devices at once, faulty wiring or outlets, or a problem with the generator itself. Solutions may involve reducing the electrical load, checking and repairing wiring issues, or having a professional inspect and service the generator.
