First twist together the wires to be joined. For larger wire use lineman's pliers to apply twist. Make the twist clockwise. Then twist on the wirenut clockwise on the wires. Wirenuts are rated as to how many wires of a certain size they can hold but in general twist by hand until you can twist no more and then about 1/2 twist with pliers. If the wirenut does not get tight it is too big or internal metal portion could be clogged in some way.
The wire nuts do not have to be inside the junction box. They must, however, be as tight as possible to keep moisture from inside the light fixture.
usually you segregate them. all whites together all blacks together all non-coated copper wires and/or green coated wires together use wire nuts to connect above-mentioned wires together
Use what is called bell wire or thermostat wire.
Use the 4 wire if possible. You would only use a 3 wire for an old appliance.You shouldn't if possible. The 3 wire has no neutral wire as the 4 wire does. Som applications require the use of a 3 wire and some don't.
There should be no joints like that inside the breaker panel. I'm pretty sure the NEC, or in my case the Canadian Electrical Code prohibits having any wire nuts/marrettes in it. Any such joints should be done outside the breaker panel in it's own junction box.
Wire nuts
To join stranded and solid wire in electrical wiring applications, you can use a twist-on wire connector, also known as wire nuts. Make sure to strip the ends of the wires before twisting them together securely with the connector. Alternatively, you can use a terminal block or a push-in connector designed to accommodate both types of wires.

Yes, but you have to use connectors designed for that purpose. Using ordinary wire nuts could cause a circuit failure due to a high resistive junction.
No, not if they are secured properly and taped up after installing the wire nut. But saying that it is really up to the local inspector to approve or disapprove. Avoid doing this if at all possible.
the depth of the wire is not as important as the type of wire and the connections. you want to put the wire deep enough to prevent accidental cutting from normal activities, 8 - 12 inches should be safe. you want to use an UF (underground feeder) type wire. you want to use water proof type wire nuts on all connections even the ground (to prevent corrosion).
For a 12-2 wire (which consists of a black insulated wire, a white insulated wire, and a bare copper ground wire), you should use a red wire nut. This wire nut size is designed to accommodate two to three 12-gauge wires, which is suitable for connecting your 12-2 wire.
he drives you nuts [like that]
Wire nuts are actually used to create secure and insulated electrical connections between wires. They twist onto the ends of the wires, creating a solid connection that is then typically covered with electrical tape for further insulation. If wire nuts are not properly twisted on or come loose, they can lead to a loss of connection, but when used correctly, they enable safe and reliable electrical connections.
Yes, you can replace a short length of 14-2 wire with 14-3 wire and not use the red conductor. Just cap off the red wire with a wire nut at both ends to ensure it is not accidentally connected to anything. Keep in mind that the unused red wire must still be properly terminated in electrical junction boxes.
