Common Questions
Why do lights dim when the microwave runs?
Voltage drop — the microwave pulls heavy current on a shared circuit and reduces voltage available to other devices. Dramatic dimming means the circuit is overloaded or has a loose connection.
My breaker keeps tripping — is it an emergency?
A breaker tripping once is normal. Repeated trips mean: overloaded circuit, wiring fault, or failing breaker. If it trips immediately when switched on, that is a short — do not use it.
What does a buzzing outlet mean?
Arcing — two conductors not making solid contact, jumping current across a gap. This is a fire hazard. Stop using the outlet and call an electrician.
