# In what scenario is it to code to use an 8 cubic inch electrical box?

I am in need of a shallow electrical box. Googling led me to this one, which is 8 cubic inches. Assuming I am using 14 gauge wire, under what scenarios is this even useful, given box fill requirements?

Assuming that I understand box fill calculations correctly, 8 cubic inches would allow for a maximum of 4 conductors with 14 gauge wire (and only 3 for 12 gauge).

If the shallow box had an outlet or a switch, that counts as 2 conductors. The hot and neutral wires would bring the total to 4. Then the ground would bring it to 5 - too much for the box.

If this box were to have two different 14/2 cables enter it, it would again be too small (2 hots plus 2 neutrals plus ground = 5).

The product overview on that page indicates "use with non-metallic sheathed cable" - I am curious to know if that's even possible!

(by the way, I see that there are larger shallow boxes that I can select from. I just want to understand why this particular one is being sold)

• The box would be legal as a termination point for a single live wire. Mar 20, 2022 at 13:32
• @AloysiusDefenestrate - I suppose that could be done...though is that something that you have ever had a need to do or seen done? Mar 20, 2022 at 14:56
• Not suggesting it’s something you’d plan ahead to do, but in renovations, you’ll sometimes find hot wires illegally abandoned. When the client isn’t interested in fixing it properly, this could be a compliant solution. Mar 20, 2022 at 17:57
