Why Is Part Of My Home Electrical Power Not Working?

©Copyright - Summary:

How to Test, Troubleshoot and Identify Home Electrical Wiring Problems: The power is not working in some areas as well as two outlets on the outside of the house.

Electrical Troubleshooting for Home Wiring

Electrical Question: The power is not working in the attached garage in our 20 yr. old house in Ontario, as well as two outlets on the outside of the house.

  • The breakers are not tripped and seem fine – measuring 120 volts between the terminals on all breakers and ground.
  • Can find two ground fault interrupt outlets that were located in the bathrooms and these are fine.
  • Any suggestions where else to look?

How to Test, Troubleshoot and Identify Home Electrical Wiring Problems

This calls for some Electrical Troubleshooting:

  • Make sure the involved circuit breakers are on. Sometimes a breaker is off even though the handle appears to be on. If this is not the case then proceed.
  • Turn off any circuits that may power this area.
  • Start at the closest outlet or junction box to what may be the source of power and begin examining the wiring and splices.
  • Repeat this process until you find the problem.
  • For an experienced electrician using a tester is necessary.
  • A tick tester is very helpful to check for power without disturbing the wiring.
  • Check the GFI outlets to make sure there is power on the LOAD Side. A GFI may be faulty and need replacing.
