Only conductors are pulled and fed into a raceway system through these locations. They must be used in conduit lines when the number of bends connecting outlets surpasses the National Electric Code’s maximum number. The size of a pull box is determined by the size and amount of conductors, as well as the quantity and diameter of raceways.

Junction or pull boxes are not designed to be part of a conduit raceway system and need to be supported to prevent bowing or sagging. Cast boxes with threaded hubs are not condulets, they are junction boxes. kwired Electron manager Location NE Nebraska Mar 11, 2020 #12 jeremy.zinkofsky said:

Boxes containing raceways on opposite walls, regardless of the offset, qualify as straight pulls. Computing the minimum dimensions of a box containing straight pull (s) is an easy calculation—simply multiply the largest raceway (trade diameter) by eight. For example, calculate the minimum dimension for a pull box with two 2-inch conduits.
Taking the Mystery Out of Sizing Pull Boxes and Junction Boxes
https://www.ecmweb.com/national-electrical-code/code-basics/article/21234199/taking-the-mystery-out-of-sizing-pull-boxes-and-junction-boxes
A pull box contains a trade size 2 and trade size 3 raceway on the left side, a trade size 3 raceway on the top, and a trade size 2 raceway on the right side. The trade size 2 raceways are a straight pull, and the trade size 3 raceways are an angle pull. What’s the horizontal dimension of this box? Solution: Left to right straight pull = 8 × 2 in. = 16 in.

Boxes containing raceways on opposite walls, regardless of where they are located or the amount of offset, qualify as straight pulls (see Figure 4). Calculating the minimum dimensions of a box containing straight pull (s) is quite simple: multiply the trade size (metric designator) of the largest raceway by eight.

For raceways containing conductors of No. 4 or larger, and for cables containing conductors of No. 4 of larger, the minimum dimensions of pull or junction boxes installed in a raceway or cable run must comply with Section 370-28 (a) (1) through (3). This section provides requirements for pull and junction boxes used on systems 600 volts, nominal, or less to ground.

As far as I know that is not a defined term. plumb bob Member Feb 14, 2014 #4 I would consider it a pull box and subject to sizing restrictions if the raceway system into which it is installed would exceed 360 degrees of bending without it edit: or any time the wire does not pass strait thru the wireway, using it as a ninety degree turn for example

One interpretation is that the junction box is not considered a raceway and the free air rating of 405A is applicable for each of the 90C RHW-2 with its 90C rated terminations. Others do consider the junction box a raceway, with each RHW-2 only good for 260A. A third opinion is that the raceway vs not a raceway question is irrelevant based on ...
