Electrical FAQs, answered by experts

Running conduits through an exterior wall is an effective method for powering outdoor spaces. From gardens to sheds to garages and more, it can be important to have electricity outdoors. Using conduit, which safely covers wires outdoors, is an easy way to get power where homeowners need it.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

You can tell if a breaker is GFCI by looking for a red or yellow test and reset button that you can press in and out. You’ll know if an outlet is GFCI if the red reset button is located in between the two pronged sections.
