What to ask before you hire

About Joshua N Frost

Worth asking any panel upgrade electrician

  • Can you show me proof of liability insurance and your bond?
  • What size panel, and does the utility need to change the service to my house?
  • Who arranges the power shutoff with the utility?
  • Who pulls the permit, and who meets the inspector?
