This depends on the size of the wire and the size of the box. Look in article 370 of the NEC code book under box fill.
If you are using a plastic box it will have info printed on the box.

How many wires in a junction box?
According to the NEC and CEC, it depends on the size of the box.
What are connecting wires?
Connecting wires in electrical terms is called an electrical splice. All electrical splices have to be made in a junction box.
What is a wire splice box?
Wires are not to be spliced or otherwise connected except in an approved electrical box. The box should be accessible, such as an electric outlet or switch box. If you decide to NOT use the box as an outlet or switch box, make certain that you use a blank cover.
Do you have to ground a junction box if there is no splice?
No <<>> The NO answer above pertains to a metallic or PVC conduit system. In home wiring, with the type of wire being used it would be near impossible to drag a cable through a switch or receptacle junction box without cutting the cable. Once this cable is cut, the grounds have to be spliced together and this ground wire is then required by code to be grounded to the box.
What is a junctions box?
A junction box is a container that holds electrical connections. The idea of a junction box is usually to keep wires safe, secure and free of dust, dirt and damp. A junction box is usually built within the layers of a wall so that all wires are concealed and the build looks neat and tidy.

Can you junction box 8ga wire with 10ga wire?
There is no restriction on different size wires being spliced in the same junction box. If your question involves splicing 8ga. to 10ga, this also is not a problem so long as the circuit allows for 10ga wire.
Illusrations of common wire splices and joints?
You can splice wires together in many ways. You can solder them together and then tape them up or use a shrink insulator that shrinks by heating it up. You can strip the wires back about 1/2 inch and then twist them together and put them under a wire nut. Wire splices in a home must be spliced together inside a junction box with a cover. Wires can never be spliced behind a wall. Any splice should be placed where you can access it later on.

How many 14 gauge electrical wires can you put in a 2x4 electrical box?
Answer varies. Is it a deep or shallow box? is there a receptical, a switch in the box as well? is it just a junction box? are they single wires or NM cable?

EXPLAIN WHAT WIRES DO IN A RECEPTACLE?
Wires bring the voltage source to the junction box of the receptacle. At this point they are terminated under the screws of the receptacle. With the receptacle screwed to the junction box and the cover plate installed the outlet is ready to be used. The last thing to do is turn the breaker back on to energize the receptacle.
Looking for a connection wiring diagram for 30 HP 3 phase 380 volt motor?
The connection wiring diagram is usually on the inside of the motor's junction box cover. If the motor has three wires at the junction box then these wires are connected to the three incoming supply wires. If there is more than three wires, check the motor's nameplate to see if the motor is a dual voltage motor.
What are the uses of junction box?
Used to connect wires together and cover them for safety. Junction boxes must never be installed anyplace they cannot be accessed at any time.
Reverse direction on a 480 ac motor?
Reverse any two of the lead wires at the motor junction box.
