Solve Home Electrical Problems Yourself !

Does your home have:

For diagnosis of home electrical problems, ever wish you had a house wiring diagram, or reliable online advice?... I am Larry Dimock, The Circuit Detective, a master electrician in Washington state who concentrated on troubleshooting home electrical problems. I used to offer email and phone advice from here, Larry used to take calls for help troubleshooting circuitsbut now that I've retired, you'll have to rely on this did-it-myself website to fix your problem, as over 11 million have since 2004. They say the site is exceptional.
U.S. and Canada only.

Decide how you will use this site:

"I may have a Common problem that might be answered quickly in a FAQs format, or with guidance from a Diagnostic tree."

"I need to understand my electrical system better first"... Then go study the Background page and diagrams.

"I know enough about breakers, outlets, and circuits, but I need tips on troubleshooting"... Then go to the Nutshell or full Troubleshooting page for step-by-step help to find the cause of your problem.

"I have no malfunction, just a question about a wiring project"... Check this Circuit diagram or this Connections tutorial or Connections catalog or Home electrical wiring.

"I guess I need to find a local electrician to come to my home." Good luck.

SLEUTH. I had fun being in this 7-minute info-video drama. Maybe you will enjoy it. It will be of special interest if you have an outage that doesn't seem to be from a tripped breaker or GFCI. More videos by Larry.

The Scope of This Website: These pages have been designed as a guide for the DIY homeowner who faces home electrical problems, that is, electric malfunction issues in his/her household electrical wiring system. The site is not mainly oriented to helping with design, installation, or with remodel projects. Some books are better at wiring projects than most websites.
The concept is Home Electrical Troubleshooting:
1. "Home" includes any residence: a house, condominium, apartment, or mobile home.
2. "Electrical" means the alternating-current house wiring system, from power company equipment, through circuit breakers or fuses, to plug-in outlets, electrical switches, and some of the appliances and light fixtures operated by this current.
3. "Troubleshooting" here means the process of investigating and fixing home electrical problems; the site is mainly not concerned with upgrading or preventive maintenance.
