The answer to 'why is my recessed lighting circuit overload' is that the circuit is drawing more electrical current than it's designed to handle. This can be caused by several common issues, such as too many recessed lights on the same circuit, faulty wiring or fixtures, or a short circuit.
Some key symptoms of an overloaded recessed lighting circuit include flickering or dimming lights, circuit breakers tripping frequently, or the lights feeling excessively hot to the touch. To resolve this, you'll need to identify and address the root cause, which may involve redistributing the lights across multiple circuits, replacing faulty components, or having an electrician inspect and repair the wiring.
