"Matt and his team did an excellent job upgrading our electrical panel. He coordinated the work with National Grid, relocated the panel, labeled the circuits and tested all the work. I would highly recommend Dever Electric."

Electrical FAQs, answered by experts

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.

It's less expensive to run power overhead because it doesn’t require excavation, and the power cables are less costly. However, underground electric service is better protected from weather and general wear and tear, so it’s less likely to get damaged. When determining which way to run power, consult a local electrician to get an expect opinion.

Knob and tube wiring is old, and its casing is brittle. This means that it's possible to receive a dangerous electrical shock if you touch a live wire and essentially become an electrical pathway. Although the scenario is unlikely, touching any K&T wiring is simply not a good idea in any instance. Leave any wire handling to the professionals.

Outlets with only two slots have no ground connection. That’s more common on very old outlets, which means it’s more likely the outlet won’t be polarized. You’ll have to closely examine the slots to see if there’s a size difference indicating polarization. Keep in mind outlets this old are usually out of code and should be replaced if you’re doing any electrical work.

Usually, your house panel is one of the key components that must be replaced when upgrading your amp service. In many cases, you will also need to upgrade your meter base as well as other electrical components.
