Splicing Cables and Wires
Learn to create secure, safe, and professional electrical connections. This course covers everything from basic wire twisting to weatherproofing and soldering for permanent repairs.
Like Duolingo, but for Splicing Cables and Wires. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
20 levels across 3 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through Making Your First Connection, Professional Joint Techniques, and Insulation and Durability. It starts from scratch.

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
