Electrical questions, answered by experts

Amps describe the amount of energy that can flow through a circuit breaker. Every electrical device that’s attached to the breaker requires about 1.5 amps. While that equates to roughly 13 receptacles per 20 amps, using slightly fewer ensures that your circuit will always have enough energy for sudden power surges instead of tripping when one occurs. In general, 10 to 12 receptacles is recommended for a 20 amp circuit.

It prevents electrical surges, protects your home from things like electrical fires, and prevents you from getting shocked if an errant surge runs through your power line. Without grounded wires, your appliances could also get damaged during lightning storms.

Short circuits can cause fires, electrical burns, and electrocution, which can lead to serious injury or even death. That’s why it’s important to take preventative measures to prevent short circuits, like getting annual electrical maintenance and an electrical inspection every two to five years, depending on the age of your home.

Flickering lights, warm outlets, or tripped circuits needing immediate attention mean systems likely risk hazard scare.

Doorbell wires typically won't spark because they carry low voltage. However, if there's a short circuit or damaged wiring, sparking could occur. Always turn off the power at the breaker box before working with doorbell wires to prevent any risk. If you notice any sparking, it's a sign of a problem that a professional electrician should address.
