B-LINE 727218-4XFFSD – Frequently Asked Questions
1) Does the B-Line 727218-4XFFSD enclosure come with a back panel or mounting rails for gear?
No. The 4XFFSD ground mounted enclosure ships with no mounting provisions inside, so any back panel, subpanel, rails or standoffs for your gear have to be ordered separately. Plan the interior mounting kit as a separate line item before the enclosure lands on site.
2) Can this fiberglass enclosure be wall mounted or does it have to sit on a pad?
Ground mount only. The 72 x 72 x 18 inch 4XFFSD is built to set on a pad or foundation, not to hang off a wall, and at 415 lb empty there is no wall mounting hardware on it. Pour or set your pad to the 72 inch width and 18 inch depth footprint.
3) Is a NEMA 4X fiberglass enclosure suitable for outdoor washdown or coastal installations?
That is exactly what the 4X rating is for. NEMA 4X covers hosedown, windblown rain and corrosion resistance, and the fiberglass shell plus a seamless poured in-place gasket is the combination specified for wet, chemical or salt-air exposure where painted steel would rust at the seams. For a dry indoor electrical room a 12 rated steel enclosure is the cheaper choice.
4) Can the doors on this B-Line ground mounted enclosure be padlocked?
Yes, it has padlock provisions, plus a stainless steel pull drawn catch on the hinged cover. The padlocks themselves are not supplied, so pick your own shackle size. For a utility or municipal site where crews need keyed access, that padlock hasp is usually what the spec calls for.
5) Will a UL 508A enclosure satisfy my industrial control panel spec?
The 4XFFSD carries UL 508A, which is the standard for industrial control panels, so it is the right shell when you are building or housing a listed control panel. Confirm your panel builder is working to the same 508A listing so the assembly keeps its label.
6) How much clearance do I need in front of this 72 inch double door enclosure?
It is a large double door style with hinged covers 72 inches tall on a 72 inch wide box, so both leaves swing outward across roughly half that width each. Leave full working clearance in front for the door swing plus NEC working space in front of the live parts inside, and keep the 18 inch depth in mind when siting it against a fence or wall.
7) How do I rig and set a 415 lb fiberglass enclosure on site?
At 415 lb empty the 4XFFSD is not a two-man carry. Budget for a forklift, telehandler or small crane to place it on the pad, and remember any gear you install inside adds to that. Set it before the interior panel and devices go in so you are handling the lightest possible unit.
8) What is the exact part number to order for the 72 x 72 x 18 B-Line ground mount 4X enclosure?
Order Eaton B-Line part number 727218-4XFFSD. The digits read out the size, 72 inch height by 72 inch width by 18 inch depth, followed by the 4X fiberglass ground mount double door designation.
9) Are conduit holes or knockouts pre-cut in this enclosure?
No knockouts. The 4XFFSD is supplied with no mounting provisions and no factory openings, which is standard for a 4X box, since any penetration has to be made and sealed in the field to keep the 4X rating. Cut your conduit entries and use watertight hub fittings with the appropriate gaskets.
10) What color is the B-Line 4XFFSD fiberglass enclosure, and can it be painted?
It ships unfinished in grey, the natural color of the molded fiberglass rather than a coated finish. If your facility standard calls for a specific color, plan on field painting with a coating rated for fiberglass and outdoor exposure.
11) Is this B-Line enclosure made in the USA?
Country of origin is the United States, which matters if you are procuring against a domestic preference clause on a government or utility project.
