Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...

The wiring inside a dwelling that you cannot see may be an arc fault waiting to happen, due to improper installation; corrosion; damage caused by rodents, insects, or other pests; penetration by ...

Proper impedance paths are critical to shock prevention. The National Safety Council estimates that nearly 300 people die in the United States each year from electric shocks on 120V or 277V circuits.
