B-LINE 20166 SCG – Frequently Asked Questions

1) What size is the Eaton B-Line 20166 SCG junction box?
The 20166 SCG enclosure measures 20 inches high, 16 inches wide and 6 inches deep, and it weighs 29.7 lb. That 6 inch depth is what decides whether your conduit bodies, terminal blocks or wire bending space fit behind the cover, so check it against the gear going inside before you order.
2) Can the B-Line 20166 SCG enclosure be used outdoors?
It is built to NEMA Type 3/3R, so it is rated for outdoor use against rain, sleet and windblown dust, and it also carries a Type 12 rating for indoor dust and dripping liquids. The seal comes from an oil-resistant gasket and gasketed cover screws. It is UL 50 listed.
3) Does the 20166 SCG junction box come with mounting feet or brackets?
No. The 20166 SCG ships with no mounting provisions, so there are no factory holes, feet or panel studs in the back. It is a surface-mount enclosure, so you supply the mounting hardware and, if you drill the back, seal the penetrations or you compromise the Type 3R rating. Plan on a separate back panel too, since none is included.
4) Is the B-Line 20166 SCG a hinged enclosure or a screw cover?
Screw cover. The medium single door cover bolts on with gasketed screws rather than swinging on a hinge. For a junction or pull box you rarely open that is fine, but if an electrician needs frequent access to terminations, a hinged-door enclosure is the easier choice on the job.
5) What is the 20166 SCG box made of, and will it rust outside?
Galvanized steel in 14 gauge, left unfinished, so the surface is the mill galvanize rather than paint. That is the standard choice for damp and outdoor Type 3R work. If you need a painted finish to match other gear on the wall, or you are in a washdown or coastal environment, look at a painted steel or stainless enclosure instead.
6) Does the B-Line SCG junction box come with knockouts?
The 20166 SCG is supplied as a sealed screw-cover enclosure with no mounting provisions, so conduit entries are field-drilled where you need them. Use sealing-type hub fittings or gasketed connectors on every penetration to keep the Type 3R and Type 12 integrity, and drill into the sides or bottom rather than the top wherever the layout allows.
