Wiremold RFBA4R30 – Frequently Asked Questions

1) What is the difference between the Wiremold RFBA4R30 and RFBA4R30OG floor boxes?
They are the same 4-gang RFB Series steel floor box in two installation versions. The RFBA4R30OG is the on-grade version, built for slab-on-grade pours where the box sits in the concrete at finished floor level. The RFBA4R30 is the flush mount version. Pick by how the floor is built: concrete slab on grade takes the OG, and the non-OG part number is the one to order for a flush mount application.
2) How much room do I need to cut or pour for the Wiremold RFBA 4-gang floor box?
The box measures 17-3/4 x 8-9/16 x 3 inches overall, so the 3 inch figure is what governs your slab depth or floor cavity, and the 17-3/4 by 8-9/16 footprint is what has to clear rebar, conduit runs, and any structural deck below. On a slab-on-grade pour, set the box before the pour and confirm the slab is deep enough to bury a 3 inch body with cover clearance to finished floor.
3) Can I run power and data in the same Wiremold RFB floor box without them sharing a compartment?
Yes. The RFBA 4-gang box uses removable dividers, so you can partition the enclosure to keep line voltage separated from communications cabling within the same 4-gang body. Take the dividers out where you want a larger single compartment, leave them in where power and low voltage share the box.
4) How many devices can a Wiremold RFBA4R floor box hold?
Four gangs in a single box. That lets you consolidate power on some compartments and data or voice on others in one floor penetration instead of running separate boxes, which is why it gets specified for open office and conference room layouts where a workstation cluster needs both receptacles and low voltage at the same point.
5) Is a floor box like the Wiremold RFBA4R the right call, or should I use surface raceway?
Use the in-floor box when the outlet has to land in the middle of the room, away from walls, and when a cord or raceway across the floor would be a trip hazard or an eyesore. The RFBA 4-gang box brings power and comms flush to the finished floor for open offices, conference rooms, retail and lobby spaces. Surface raceway or perimeter wiring is the simpler answer when the devices can live at the wall line, and it stays the better choice on an existing slab you do not want to cut.
6) Will the Wiremold RFBA4R floor box work in a raised access floor or a wood-framed floor?
It is sized and intended for concrete floor construction, with the OG version specifically for on-grade slab pours and the flush mount version for flush installation in the finished floor. A raised access floor or a joist-framed wood floor is a different problem and calls for a box designed for that deck type, not an on-grade concrete box.
7) Do I get the cover and device plates with the Wiremold RFBA4R30 box, or are those ordered separately?
What is described here is the 4-gang steel box itself, the enclosure with its removable dividers that gets set into the floor. Cover assemblies, carpet or tile flanges, and the device plates that finish the opening are separate line items on RFB Series jobs, so plan the order around the box plus the cover trim that matches your floor finish.
