When to call a professional

Electrical work

Most of this is yours to do. Call someone licensed if any one of these is true — it's a judgement call, not a defeat.

  • The breaker trips again after you reset it once.
  • You see scorch marks, melted plastic, or smell burning.
  • The wiring is cloth-covered, aluminum, or has no ground.
  • The work is inside the main panel or the meter.
