Electrical questions, answered by experts

You will need a permit for any electrical work that involves installing or replacing wiring, moving or installing new fixtures, switches, or outlets, hardwiring appliances or HVAC equipment, installing subpanels, and upgrading electrical service. You typically don’t need a permit to have an electrician replace an existing light fixture or electrical box. You can always call your local building department to see if your project needs a permit, but a professional electrician will be able to tell you. In most cases, your professional will pull the permits for you.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

Yes, many remodels include electrical upgrades for lighting, outlets, or charging stations. Confirm with your contractor.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.
