American Fittings SS52BUS – Frequently Asked Questions

1) Is the American Fittings BUS set screw connector for EMT or for rigid conduit?
The BUS Series is a set screw connector for EMT. Set screw fittings grip the outside of the tubing with a screw rather than threading onto the conduit, so they suit EMT runs terminating into boxes, panels, and enclosures. Rigid and IMC terminations use threaded fittings instead, not a set screw body.
2) What trade sizes does the BUS set screw connector come in, and what part number do I order?
Two sizes: 3/4 inch, ordered as SS51BUS, and 1 inch, ordered as SS52BUS. Both are the insulated-throat set screw version in zinc-plated steel.
3) Do I need an insulated throat connector, or will a standard steel set screw connector do?
An insulated throat matters when you are pulling conductors through the fitting, because the plastic liner keeps the metal edge off the wire insulation. The BUS Series carries that liner built in, so you do not add a separate bushing. Plain-throat set screw connectors are fine where nothing is pulled through at that point, but many inspectors and specs call for insulated throats on larger conductors.
4) Is a zinc-plated steel set screw connector okay in a damp or outdoor location?
Zinc plating on steel gives corrosion resistance for general commercial, industrial, and residential work, and that is the intended use here. Set screw fittings are not raintight, though, so for wet locations or outdoor runs use a raintight compression connector instead of the BUS set screw style.
5) Does a set screw EMT connector come with the locknut for the box?
Set screw connectors of this type ship with the locknut that secures them through the box or enclosure knockout; you thread the connector through the knockout and tighten the nut on the inside. The insulated throat is part of the fitting, so no extra bushing is needed.
