Will you work inside a breaker panel, service equipment or on unknown live wiring?Can the circuit or component be safely de-energized before testing?Does the meter state an appropriate CAT rating and voltage for the location?

This guide cannot make live electrical work safe. Never exceed the meter, lead or accessory ratings. When the location or procedure is uncertain, stop and hire a licensed electrician.
