Electrical questions, answered by experts

The most common gauge for indoor outlets around your home is 12- and 14-gauge wires. But if you’re working with larger appliances like ovens, washing machines, or dryers (all of which require more amplitude), you might find 10-, eight-, or six-gauge wires to help support those hefty appliances.

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.

Yes, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.

Before hiring, you should verify the electrician's license, insurance coverage, and any third-party certifications. You can use Angi’s contractor licensing search to confirm a pro's license status. Additionally, businesses with the “Angi Approved” badge on our platform meet strict criteria, including having the required state and local licenses, passing a background check, and maintaining a high average rating.

It's possible to get power from an outlet for a light switch. However, you must install additional wiring to get current from the outlet to the switch and from the switch to the load it will control. Also, you must ensure that the outlet's electrical circuit can accommodate the additional demand. 

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.
