What are tools and materials?
“Tools and Materials” contains lists and examples of useful tools and resources in making activities and makerspaces, including suggestions for consumables, hardware, machines, open source software, and other technologies.

If you’re adding an outlet, you need to use wire the same gauge as the existing wiring.
What are the types of wire?
Types of Wire – A Thomas Buying Guide
- Fuse Wire. Fuse wire has a low resistance to allow normal current to pass safely through it, but if there is a short circuit that causes a higher voltage current to pass through it, the fuse wire can’t withstand the heat, so it melts and breaks the circuit.
- Magnet Wire.
- Litz Wire.
- Tinsel Wire.
- Wire Harness.
What are the different types of wiring devices?
Wiring devices include:
- Convenience plugs and power outlets (plugs and receptacles)
- Connector bodies and flanged outlets.
- Cover plates.
- General-use switches and dimmers.
- Lampholders (incandescent, fluorescent, cold cathode, neon, quartz lamps, and others)
- Lighting control devices.
- Motion sensing and timer switches.
Is most residential wiring 3 phase?
From a technical aspect, most residential wiring are single phase and 120 Volts, consisting of three wires, positive, negative, and neutral. In three phase electrical systems, there are two smaller legs running 120 Volts each and i wider leg running 208 Volts.
How many types of house wiring are there?
Can I mix 12 and 14 gauge wire?
Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.

Should I use 12 or 14 gauge wire?
As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.
Can I use 14 gauge wire on a 20 amp breaker?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.
Can I mix 12 and 14 gauge wire on a 15 amp circuit?
It is perfectly acceptable to use 12 gauge wire on a 15 amp circuit. It shouldn’t, many older homes were wired with 12 gauge throughout. Apart from that, it is actually explicitly allowed by code.
What is 14 gauge wire used for?
14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.
