Box fill calculation for 3/0 wire? Table 314.16(B) does not list an allowance.

[brycenesbitt]

So I need to do a box fill calculation for a 384 cubic inch box. I'm at table 314.16(B)

AWG	Cubic inches
18	1.5
16	1.75
14	2.00
12	2.25
10	2.50
8	3.00
6	5.00

One of my grounded conductors is 3/0 size, the rest are #10. How do I calculate the required volume allowance?

You use the 6X or 8X rules for conduit entries.
