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:
- 'Home' includes any residence: a house, condominium, apartment, or mobile home.
- '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.
- 'Troubleshooting' here means the process of investigating and fixing home electrical problems; the site is mainly not concerned with upgrading or preventive maintenance.
