B-LINE 4448 G – Frequently Asked Questions
1) What size is the Eaton B-Line 4448 G wiring trough, and how much wire fill does a 4x4 cross section give me?
The 4448 G is a 4 inch by 4 inch cross section, 48 inches long. That 16 square inch interior is the standard NEC wireway size step most branch-circuit gutter runs are sized around, and it is the common choice for pull boxes and junction runs feeding panels. If your conductor count needs more room, step up to a 6x6 or 8x8 trough rather than doubling up on 4x4.
2) Is this wireway rated for outdoor or wet locations?
No. The 4448 G trough is a NEMA 1 enclosure, which is indoor, general purpose only. It protects against incidental contact and falling dirt, not rain, washdown, or dust ingress. For an exterior wall, a rooftop run, or a wet process area you need a NEMA 3R or NEMA 4 gasketed trough instead.
3) Does the 4448 G wireway come with knockouts already punched, or do I have to drill it?
It comes punched. There are 15 knockouts on the top and 15 on the bottom, so you can land conduit into the trough at regular intervals along the 48 inch run without a hole saw or a punch set on site. Mounting is by thru holes in the back of the body.
4) Is this a hinged cover or a screw cover trough?
Screw cover. The lid on the 4448 G is secured with plated screws the full length of the body, which is what you want where the cover has to stay put and inspectors expect a fixed closure. If you are pulling and re-pulling conductors often and want one-hand access, a hinged-cover trough is the easier product to live with.
5) Is the Eaton B-Line 4448 G trough certified for a job that requires listed electrical enclosures?
The 4448 G carries CSA certification. That is the rating stated for this trough, and it is what a specifier or inspector will be looking for on the label when the submittal calls for certified wireway.
