How many 14 awg wires can be put into a single gang box with a switch?

Answer 1

For the typical size (I think 18cu. in. box), you can fit 9. Look inside the box on the back wall. it should list how many wires you can have in the box for different gauge wire, typically for 14awg, 12awg and 10awg wires, e.g. 9/14.

To count the wires: 1 for each white, 1 for each red, 1 for each black, 1 for all the grounds, 1 for each switch, and 1 for each outlet.

Example A: the box has two 14-2 wires for power and one 14-3 for the 3-way switching, and one 3-way switch: 3 whites + 3 blacks + 1 red + 1 for all ground wires + 1 switch = 9

Example B: two 14-2 wires and one outlet: 2 white + 2 black + 1 for ground + 1 outlet = 6

Not all electrical boxes are the same size or rating so look at the specs to see how it is rated.

Answer 2

Typically, a single gang box can accommodate up to 8-10 14 AWG wires in addition to the switch. Be sure to check the specific box size and wire capacity as some boxes may vary in size and space limitations. Consider consulting the National Electrical Code (NEC) for further guidance on wire capacity.

Answer 3

As many as you can easily fit inside.
