How to twist electric wire together

how to twist electric wires


twist two electric wires
connect stranded wire and solid wire How to connect stranded wire and solid wire
If stranded wire is thinner than solid:
Strip back stranded wire so there is more copper visible than solid wire.
Wrap stranded wire around solid copper.
Leave solid wire straight.
When connecting two solids and one stranded: twist solids together first, then wrap stranded wire around solids.
Apply wire nut very tight.
Pull stranded wire to make sure it is tight.
If stranded wire is same diameter as solid:
Cut off both same length
Don't twist together, cover with wire nut.
Twisted wire1) Strip stranded wire longer
2) Wrap stranded around the solid wire
3) Twist wire nut over both wires
4) Twist wire nut very tight
5) Pull stranded wire and make sure it will not come loose

          

Look inside wire nut and see steel spring.
Screw on wire nut and steel spring cuts into soft copper wire.
Tighter you screw wire nut, the stronger the steel spring holds the wires together.

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

Both wires MUST be same gauge
Straighten each wire
Tighten screw very tight against copper wire

Connect stranded and solid with wire nut and run jumper to screw plate.
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.
