Key ideas in Splicing Cables and Wires
- The insulation should be removed without the blade touching the metal
- Wires must be physically intertwined to stay together
- Nicks create a weak point where the wire will eventually snap
- A loose twist will pull apart under tension
- Bending a nicked wire concentrates stress on the damaged spot
- The mechanical wrap is what holds the weight, not just the tape
- The consequence of damaging the metal core while stripping insulation
- The process of creating a mechanically sound twist
- More surface contact allows electricity to flow easily
- Small contact points create 'resistance' which generates heat
- Winding wires along each other maximizes the touch points
- A firm pull (tug test) reveals if the twist is actually locked
- If the wires slide at all during a pull, the splice is a failure
- Wire nut colors indicate the maximum and minimum wire volume they can safely hold
- Using a nut that is too small for the wire gauge prevents the spring from fully engaging
- The relationship between wire contact and heat
