The value is 2.00 cubic inches, so multiplying that value by 2 gives you the 4.00 cubic inches for the installed device.ģ) C, straps.

To find that value, go to Table 314.16(B) and find the value for 14 AWG conductors. For example, if a switch on a yoke is connected with 14 AWG conductors, the switch volume allowance would be 4 cubic inches. 314.16(B)(4) requires a double volume allowance for device or equipment fill. Use of messenger-supported wiring if specifically permitted by other articles of the NEC.Ģ) B, double.
