Electrical questions, answered by experts

It’s important to ask an electrician a few questions before you commit to hiring them so you can make an informed decision as a consumer. If you’re getting estimates or considering hiring an electrician, ask them these questions:

  • Are you a full-time electrician?

  • Are you bonded, licensed, and insured?

  • What level of experience do you have as an electrician?

  • Can you please share three references?

  • Do you do residential or commercial electrical work?

  • What kinds of electrical work are you most familiar with?

  • Will any subcontractors be performing the work?

  • Are permits and inspections required?

  • Who is responsible for obtaining permits and inspections?

  • What is your schedule?

  • Do you offer a guarantee or warranty on your work?

  • Will you sign a do-not-exceed clause to keep the job within the budget?

Yes, a whole-house surge protector needs a designated breaker in your electrical panel. You will need to choose a double pole breaker that has two wire terminals so that your surge protector can connect to the breaker. This breaker needs two breaker slots inside of your panel. If you do not have room, then you will either need to adjust some of the existing breakers in the panel box or hire an electrician to install a subpanel.

GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

Typically, when a 3-way switch only works when one switch is on, this is one of the most telltale indicators that the switch has gone bad (although this could also be the result of faulty or loose wiring). To diagnose the issue, toggle each switch until the light comes on. Once it’s on, toggle each switch separately again; the switch that doesn’t turn the light off is the bad switch. 

For more complex electrical projects, it’s often most efficient and cost-effective to hire an electrician rather than trying to figure it out yourself (and risking electrical problems). Electricians know exactly what a project requires, and can often find supplies or parts for cheaper than the average homeowner. That can save money compared to going it alone.
