About the PVC 3-Gang Box 44 cu.in.

The PVC 3-Gang Box 44 cu.in. provides 44 cubic inches of volume for electrical connections. This pvc box is commonly used for triple switch installations, media centers. With dimensions of 5-3/4" x 3-1/4" x 3", it offers adequate space for most residential and light commercial applications.

Box Fill Calculation Example

For a typical installation using 14 AWG conductors:

  • Box volume: 44 cu.in.
  • 14 AWG conductor volume: 2.00 cu.in. each
  • Maximum conductors (theoretical): 22

Remember to account for devices (2× conductor volume each), internal clamps (1× conductor volume), and equipment grounding conductors (1× conductor volume for all grounds combined).

Practical Example: Receptacle Installation

Installing a duplex receptacle with two 14/2 NM cables in this box:

  • 4 × 14 AWG conductors = 4 × 2.00 = 8.00 cu.in.
  • 2 × grounds (count as 1) = 1 × 2.00 = 2.00 cu.in.
  • Internal clamps = 1 × 2.00 = 2.00 cu.in.
  • 1 × receptacle = 2 × 2.00 = 4.00 cu.in.
  • Total: 16.00 cu.in.

Result: 16.00 cu.in. ≤ 44 cu.in. = COMPLIANT
