Wire Nuts Steps: 1. Scott explains the color and size of wire nuts are very important. Each color and size can handle a different amount of wires and gauge size.
2. Scott says the packaging on wire nuts typically shows which wire nuts work best which what gauge wires and the amount of connections it can handle. 3. Scott explains when wires were first spliced, they were soldered together like copper pipes in plumbing and covered with electrical tape. But the dangers were high for those type of connections. 4. Scott says the next type of connection was a copper coupling which covered the wires and bound them together. The coupling was then crimped to hold the splice firmly.
5. Scott shows Kevin how to splice two wires by lining up the insulation on both wires and twisting them together with lineman pliers. Once a solid connection is made, cut off the tip of the splice and cover it with a wire nut and ensure no copper is showing. Follow This Old House and Ask This Old House: Facebook:
