314.16(B)(6) Terminal Block Fill.
A terminal block in a box counts for a single volume allowance in accordance with Table 314.16 (B) (1). This is for each terminal block assembly based on the largest conductor terminated to the assembly.
TERMINAL BOXES
12 terminals Four M25 cable gland entries available at every 90 degrees for easy connection of external CT wiring to terminal box contacts.
Choosing Between Terminal Box and Junction Box
Terminal Boxes are larger and made of strong material that can keep various terminal blocks within. It also has multiple entry points to handle a large number of cables and wiring.
