Screw on wire nut and the steel spring cuts into the soft copper wire.
The tighter you screw the wire nut, the stronger the steel spring holds the wires together.
Choose the right size wire nut
> Does nut cover past the copper wire?
> Is nut tight enough that it will never fall off?
Answer 'yes' to both questions, you have right wire nut.

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. |
