Electrical questions, answered by experts

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

Yes, U.S. municipalities require electricians to hold an electrical contractor’s license. In some cases, a certified electrician will send an apprentice or journeyman that works underneath them, but the primary electrician still needs to hold the proper license. Without an electrical contracting license, your professional won’t be able to pull the proper permits for your project. You can use Angi’s contractor licensing search to confirm that an electrician you’re considering hiring is fully licensed. Don’t forget to verify the electrician’s insurance coverage and any third-party certifications before hiring.

The safest option is to let a technician conduct the inspection. However, if you are certain that the capacitor failed and you take all precautions to avoid electric shock, you can take a look yourself. Usually, you can open the front panel of the unit and use a flashlight to find the small capacitor cylinder. It should have a sticker on it that provides its product number, capacity, and similar information that you can note when talking to a contractor.
