Questions & Answers

Is there a fire rating for the RFB4 above grade boxes? Also can you use the RFB Above grade boxes on Grade level?

Asked by: Brian
Hi Brian, The RFB4 does not carry a fire rating. This box is stamped steel for above grade concrete applications, not rated for on-grade applications. For on grade applications I would suggest the RFBA4R30OG box instead. There is no fire rated version of that series.

Can the cover FPBTBK be installed on bare concrete floor finish or is tile only option?

Asked by: Claude
Hi Claude, The FPBTBK is for tile or hardwood flooring only. For bare concrete you need a bare concrete adapter ring (FP-CTR) installed on the box prior to the concrete pour. That bare concrete adapter must be used to provide a flush installation. The flanged blank cover, FPBTCBK, will then be needed to sit flat in the FP-CTR adapter.

Does the RFB4 have conduit access on the bottom of the box?

Asked by: Mike H
The RFB4 has knockouts for conduit access on the bottom in the two compartments that are intended for power outlets. One compartment has a 1" KO and a 1-1/4" KO. The other has a 3/4" KO and a 1" KO. The side compartments which are for communications do not have bottom KOs.

Can these boxes be retrofit into existing concrete floor?

Asked by: Mike
The most common installation for the RFB4 floor boxes is in a new concrete pour for slabs above grade. However, the RFB4 floor boxes can also be installed in existing slabs above grade. You will have to trench the floor to accommodate the box and the conduits that feed into it. You will also have to re-pour concrete to fill the trench and re-finish the floor. Any trenching must be done with the direction of a structural engineer to ensure that it will not affect the integrity of the concrete slab.

Can this floor box accommodate a NEMA 6-20 receptacle?

Asked by: Walt
The RFB4 cannot accommodate a NEMA 6-20R receptacle as we do not offer a device plate compatible with that type receptacle. If you do not already have the RFB4 box, we suggest using the RFBA4R30 box instead. The RFBA4R30 can accept the 6-20R using an RFBAS1 device plate, and it takes the same type cover as the RFB4 (Floorport series). Here's a link to the cutsheet for the RFBA4R30. https://legrand.webdamdb.com/directdownload.php?ti=55670796&tok=CZPWcVfOP8SAdEXsX91/9gRR
