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
Depending on the size of the wire, you can use wire-nuts for the smaller gauges Do not twist solid and stranded wire together when you use wire-nuts. Just lay the exposed conductor side by side and apply the wire-nut. If you wrap the two wires together, it was found, some connections have pulled apart due to the wire-nut not biting into the solid wire as the stranded wire was wrapped around it. Split bolts for the larger sizes and Allen key wire lugs bolted together for big size wire.
yes, or tie together 2 condutors into one. Yes you can, but cover the two ends of the red wire with wire nuts and tape them up with electrical tape.
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.
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).
No. Use roasted nuts.
Wire nuts don't disable an electrical connection you have to kill the power for that. What they do is isolate the wires so that the positive and negative wires don't touch and protect you from a bear electrical connection.
Look on the box or bag that the wire nuts came in, there you will find all of the combinations of wire sizes that can be connected together under one nut.
he drives you nuts [like that]
