Safety when testing wires:
Never touch wet or previously flooded appliance.
Never stand on wet surface when working on electric.
Never stand on bare soil, put down dry boards.
Tape tester leads to wood sticks to keep hands away from power.
Use non-contact voltage tester before touching wires.
Never touch or lean into any made of metal.
Remove metal objects from pockets.
Do not use oxygen or fuel accelerants in same room as electrcial repairs

Or add solder to stranded wire to make solid.
See example image

Fire safety

Use only solid copper wire, and no insulation under screw plate.

Max 2 wires under screw plate

Both wires same gauge

Do not use stranded wire, it will come loose with heat expansion and overheat and cause burning. Turn stranded wire into solid wire by soldering stranded wire.

Always keep enclosure (box) cover closed

Household NM-B Wires are color-coded so inspectors/ electricians can easily identify which wire is used during construction

Match wire size and breaker amp rating

If your home was wired by professional electrician who pulled permits, then circuit breaker and wire size will match. If manufactured home or travel trailer has not been altered by homeowner then breaker and wire size will match.

If breaker is oversized for wire... fire danger

Breaker can let too much electricity travel through the wire. Wire can overheat and cause fire.
Call electrician if you suspect wiring is not correct,
Absolute electrocution danger when removing cover off main panel. More information below.
Main breaker terminals are still Hot when main breaker is turned off.
