Wiremold 880W1 – Frequently Asked Questions

1) How big is the rough-in opening needed for a Wiremold 880W1 floor box?
The 880W1 box body measures 4-15/16 x 3-3/4 x 3-7/16 inches, so your floor opening has to clear that footprint. Catalog spec data also lists it as 5 in wide by 4.5 in deep by 3.5 in high, which is the figure to rough to if you want a little clearance around the shell. At 3-7/16 inches of box depth it needs a slab or deck pour deep enough to bury the body and still leave the cover flush with finished floor.
2) Does the Wiremold 880W1 floor box come with a cover?
No. The 880W1 is the box body only, a 1-gang steel shell. You order the cover, carpet or tile flange, and the device separately from the 880W Series line of matching covers and components. Plan the cover and device into the same order or the box arrives with nothing to finish it.
3) Can I put power and data in the same Wiremold 880W1 box?
Not separated. The 880W1 is single gang, one device opening, so it takes either a power receptacle or a low-voltage insert, not both with a divider between them. If you need power and data at the same floor location, run two boxes or step up to a multi-gang 880W Series box.
4) What is the difference between the Wiremold 880W1 floor box and the Pass & Seymour TM1542 floor box?
The material is the main dividing line. The Wiremold 880W1 is a 1-gang floor box fabricated from steel, while the Pass & Seymour TM1542 Series floor box is PVC. Steel gives the 880W1 rigidity against foot traffic and the mechanical stresses of an embedded floor pour, and it is part of the Wiremold 880W Series platform, so covers and accessories are selected from that family rather than mixed between brands. A PVC box such as the TM1542 is a non-metallic enclosure and is wired and bonded accordingly. For a single-device power or low-voltage floor outlet, both are 1-gang class boxes, so the choice usually comes down to whether the specification on the drawing calls for a metallic or non-metallic floor enclosure.
5) If the spec calls for a non-metallic floor box, is the Wiremold 880W1 still the right choice?
No. The 880W1 is a steel floor box, so if the drawing or inspector requires a non-metallic in-floor enclosure, you need a PVC body instead - the Pass & Seymour TM1542 Series floor box is a PVC floor box and fits that requirement. Keep the 880W1 where a metallic box is acceptable or specified and you want steel's resistance to crushing and distortion during the pour.
6) Is 53 cubic inches enough volume for a floor receptacle with wires passing through?
53 cubic inches is generous for a single device. For reference, box fill math under the NEC counts 2 cubic inches per 12 AWG conductor and 2.25 for a device yoke pair, so a 1-gang floor outlet with feed-through 12 AWG branch wiring and a ground is nowhere near the limit. That headroom is the main reason installers pick a steel floor box over a shallow pancake style.
7) Steel or PVC floor box, which should I use in a concrete pour?
Steel, like the 880W1, is the choice where the box takes mechanical abuse or foot traffic directly and where you want the rigidity to hold position during a pour. A nonmetallic box such as the Pass & Seymour TM1542 Series PVC floor box is the alternative when corrosion or moisture in the slab is the bigger concern. With steel you also have to carry the equipment grounding path through the metal enclosure, which some inspectors prefer to see bonded explicitly.
8) Will the 880W1 hold up to foot traffic in a retail or office floor?
That is what the steel body is for. The 880W1 is fabricated steel rather than plastic, so it resists the crush and flex of an embedded floor install under traffic in offices, retail, and hospitality spaces. The load actually transferred to a walked-on floor box is carried largely by the cover and the surrounding floor, so pair it with the matching 880W Series cover rated for your floor type.
9) Is the Wiremold 880W1 suitable for a renovation where I am cutting into an existing slab?
Yes, it is used in both new construction and renovation floor box work. The limit is depth: you need 3-7/16 inches of clear space below finished floor for the body plus room to bring conduit into it. Over a thin topping slab or a wood deck with shallow joist space, measure before you commit, because a box this deep will not fit everywhere a surface raceway would.
10) I need more than one device in the floor - does the 880W1 cover that?
Not by itself. The Wiremold 880W1 is a 1-gang box with a single device opening and 53 cubic inches of interior volume, sized for one power or low-voltage device. For two or more devices at the same location you need a multi-gang box from the 880W Series platform rather than ganging 880W1 bodies together, since the cover and device plate are matched to the box footprint.
11) What exact part number do I order for the Wiremold 1-gang steel floor box?
Order Wiremold 880W1. That is the manufacturer part number for the 1-gang steel box in the 880W Series, and it is the number to put on a submittal or a purchase order. Covers and devices carry their own 880W Series part numbers.
12) What does a Wiremold 880W1 floor box weigh and where is it made?
Each 880W1 box weighs 2.44 lb and is made in Mexico. Light enough that a case of them is easy to spread across a floor layout, and the weight is useful for freight math when you are ordering boxes by the dozen for a full office fit-out.
