Can you extend electrical wire without junction box?
Short answer: NO. Long answer: All splices must be in a junction box, and the junction box must be accessible.
How many wires can be spliced in a junction box?
Choose the Right Junction Box
For example, the smallest 2-by-4-by-1-1/2-inch-deep box can comfortably splice only two cables (four or five conducting wires), while the largest 4-by-4-by-2-1/8-inch-deep boxes can handle as many as four to six cables (up to 18 individual conducting wires).
How many wires can you pigtail together?
The only appropriate way to wire a receptacle in a box with three cables is to use pigtails to connect the receptacles. Never connect more than one wire under a single screw terminal.
Do wire nuts count in box fill?
Locknuts, bushings, wire connectors and other small fittings are not counted in box-fill calculations. (See Figure 1.) Each conductor originating outside the box that is terminated or spliced inside the box must be counted once.
Can you splice 5 wires together?
The answer is yes as long as you use the right size wire nut for the size of the wires that you are splicing.

How many hot wires can share a neutral?
One neutral may not have two “hot” wires from the same phase. It is good practice to use four (4) pole Circuit breakers (as opposed to the standard three pole) where the fourth pole is the neutral phase, and is hence protected against over current on the neutral conductor.
Can I borrow a neutral from another circuit?
No, you can’t steal a neutral wire from another circuit. Each neutral wire is the return for the corresponding hot. If you “steal” a neutral from another circuit you run the risk of overloading that neutral wire (overheat, fire risk). Another issue might arise if the circuit later becomes a GFCI.
Can 2 outlets share a neutral?
What is a multiwire branch circuit? A multiwire branch circuit is a branch circuit with a shared neutral. This means there are two or more ungrounded (hot) phase or system conductors with a voltage between them and a shared neutral.
