Replace an Outlet or Light Switch
Standard, GFCI, and What Goes Wrong
The most common home electrical job — a dead or failed outlet, a broken switch, an upgrade to GFCI. Ten minutes when you know what you're doing. The book walks what to check first, how to wire it, and what makes it fail.
About This Guide
One switch. Two wires. Easy to do right, easier to do wrong.
Outlet and switch replacement is the most common home electrical repair and the most common thing homeowners DIY without knowing enough to be safe.
This book walks the full job correctly:
- The three-step safety protocol (breaker, test, test again).
- Standard outlet replacement (duplex, 120V).
- GFCI outlet replacement (and when code requires it).
- Light switch replacement (single-pole, 3-way, 4-way).
- Reading an existing wiring configuration.
- The back-stab-vs-screw terminal choice that affects reliability.
- Wire nut sizing and technique.
- Common failures and what they mean (burned outlet, hot-to-neutral
- reversed, dead GFCI).
Written for the homeowner who wants basic electrical competence — the foundation for every other electrical project in this series.
