The answer to 'why is my dimmer switch power surge' is that a dimmer switch can cause power surges due to several common issues. Dimmer switches work by regulating the amount of electricity flowing to the light fixture, which can sometimes lead to voltage fluctuations and power spikes. This is often caused by an overloaded circuit, faulty wiring, or compatibility issues between the dimmer and the light bulb.
Some key symptoms of a dimmer switch power surge include flickering or pulsing lights, buzzing noises from the switch, and sudden power losses. If you're experiencing these issues, it's important to troubleshoot the problem promptly to avoid damage to your electrical system or lighting fixtures.
