Electrical questions, answered by experts

The number of outdoor outlets that can be on one circuit depends on the circuit's capacity and the electrical load of each outlet. Outdoor outlets should ideally be on a dedicated circuit that is not shared with other outlets, and each outlet should be rated for at least 15 amps. A circuit rated for at least 20 amps is recommended. It’s important to use GFCI protection for all outdoor outlets to prevent electrical shocks. Overall, it's crucial to avoid overloading the circuit and take necessary safety precautions.

Knowing if and when your circuit breaker is failing or faulty can prevent costly damage. If you notice any of the following signs, call a local electrician to help. 

  • The breaker frequently trips

  • The breaker doesn't stay in the 'on' position or reset properly

  • You hear buzzing or humming noises coming from the breaker

  • There's discoloration around the breaker switch

  • There's a burning smell or visible signs of damage on the breaker

There are several indicators that a single-pole switch is bad: the switch is warm or hot to the touch, sparks are sometimes present when turning the switch on or off, you hear a buzzing sound or other weird noise coming from the switch, the connected light flickers when you turn on the switch, and the light doesn't turn on at all with the switch. If you notice any of these, replace the switch or call a pro straight away.

Though they may seem similar at a quick glance, outdoor electrical outlets are different from indoor electrical outlets in that they have extra safety precautions to prevent electrical hazards. These include GFCIs, which some indoor outlets have, and a watertight cover that allows you to use electricity from the outlet even on a rainy day.

Smart light switches are designed to be compatible with most lights and traditional home wiring, but there are several key factors to check. First, verify your home's wiring, as some smart switches require a neutral wire to operate, which may not be present in older houses (often built before 1985). Always check the wiring requirements for the specific model you choose. Second, consider your light bulbs; while smart switches work with almost any light, using a dimming feature requires dimmable bulbs, such as dimmable LEDs. Finally, ensure you have the necessary network connection. Most smart switches need a Wi-Fi connection for remote control, but some older models might use other standards like ZigBee, which would require a compatible hub.
