B-LINE 66-4XSFBC – Frequently Asked Questions
1) Is this B-Line box connector rated for washdown or outdoor use?
It carries a NEMA 4X rating, so it holds up to hosedown, washdown, and corrosive environments as well as outdoor exposure. The stainless steel construction is what earns the 4X corrosion resistance, which is why it gets specified in food processing, wastewater, and coastal installs rather than a painted steel fitting.
2) Do I need to use a 4X rated fitting to keep my wireway enclosure rating intact?
Yes. A NEMA rating is only as good as the weakest fitting in the run, so a 4X wireway system needs 4X fittings at every transition. The 66-4XSFBC stainless box connector is the 4X-rated feed through fitting for that purpose; dropping a standard painted or general purpose connector into the same run gives up the washdown and corrosion rating for the whole assembly.
3) Is the B-Line 66-4XSFBC UL Listed for an inspected commercial job?
It is UL Listed, which is what an electrical inspector looks for on a wireway transition fitting in a commercial or institutional install. Combined with the 4X rating, it is the fitting specified where the wireway passes into an enclosure in a washdown-rated area.
4) What is the difference between a feed through box connector and a regular wireway connector?
A feed through connector is a pass-through: conductors run from the wireway directly into the box or enclosure with no break, no splice compartment, and no change of direction. If you need to turn a corner, tee off, or make splices at that point, you want an elbow, tee, or a pull box instead. The 66-4XSFBC is the straight feed through version.
5) Will the brushed stainless finish on this connector match my existing stainless wireway?
It is stainless steel with a brushed finish, the same finish B-Line uses across its 4X stainless wireway line, so it blends into an existing stainless run rather than standing out the way a painted or galvanized fitting would. For facilities standardizing on stainless for hygiene or corrosion reasons, that keeps the whole raceway one material.
