Choosing the Right Electrical Box for Your Project. Selecting the appropriate electrical box depends on several factors, including construction, wiring method, devices, location, and safety. Type of Construction. Your project’s construction type influences the choice of . When you're installing electrical wires in a box, you need to make sure the box is big enough to accommodate them. The National Electrical Code (NEC) specifies the minimum volume of boxes for different numbers and sizes of wires. This is to prevent overheating, short circuits and fire hazards. Electrical boxes come in metal and plastic and in a wide range of shapes and sizes. Choosing the right size is important because it's unsafe—and illegal—to cram too many wires and devices into a box. Both plastic and metal electrical boxes are suitable for most household projects.
Table 314.16 (B) gives the volume required for each conductor of a given size. As you can see, each AWG 12 conductor required 2.25 IN3 (Cubic Inches). So, if a box has to hold the following conductors—four No. 14, four No. 12, and two No. 10 conductors—the math is pretty simple. Four No. 14 @ 2.0 IN3 = 8.0 IN3. Four No. 12 @ 2.25 IN3 = 9.0 IN3.Table of Electrical Box Sizes vs Number of Wires Allowed.

I installed a spa sub-panel on the exterior of my house. The inside wiring is NM-B 6AWG cable that goes to a junction box where it's spliced to 6AWG direct bury cable (the NM-B wire I had wasn't long enough, so it was cheaper to splice). The splice was done with split bolts, wrapping 3M Temflex rubber splicing tape, then wrapped in electrical tape.
