Why do electric lights and sockets trip at the same time?

Electric lights and sockets may trip simultaneously due to a shared circuit or overload. If too many devices are drawing power from the same circuit, it can exceed the circuit's capacity, causing the breaker to trip. Additionally, a fault, such as a short circuit or ground fault, affecting multiple outlets or fixtures can also trigger a simultaneous trip. Checking the circuit's load and ensuring devices are correctly wired can help prevent this issue.
