The answer to 'recessed lighting circuit overload' is that a recessed lighting circuit overload is typically caused by too many recessed lights or other electrical devices being connected to the same circuit, causing it to become overloaded. Symptoms may include flickering or dimming lights, circuit breakers tripping, or even a complete loss of power to the affected lights. To resolve this, you'll need to reduce the electrical load on the circuit by removing some of the recessed lights or other devices, or by adding additional circuits or upgrading the electrical panel to handle the increased load.
If you're not comfortable working with electrical circuits, it's best to call a licensed electrician to diagnose and resolve the issue. Attempting to fix an overloaded circuit on your own can be dangerous and may lead to further damage or even fire hazards.
