American Fittings ERC250CPLG – Frequently Asked Questions

1) Can the American Fittings ERC coupling join EMT to rigid conduit, or is it EMT only?
It is dual rated, so it lands on both EMT and rigid conduit. That is the point of the ERC line: one fitting covers both raceway types on the same job, which cuts what you have to stock on the truck. The connection is compression on both ends, so no threading is required to make it up.
2) What trade sizes does the American Fittings ERC dual-rated compression coupling come in?
Four sizes, all in the large-conduit range: 2-1/2 inch (ERC250CPLG), 3 inch (ERC300CPLG), 3-1/2 inch (ERC350CPLG) and 4 inch (ERC400CPLG). If your run is 2 inch or smaller you need a different fitting series; this one starts at 2-1/2.
3) Does this coupling meet the UL listing my inspector will look for on a large EMT run?
The ERC coupling is listed to UL 514B (conduit and cable fittings) and UL 467 (grounding and bonding equipment). The UL 467 listing is the one that matters if the raceway is serving as an equipment grounding conductor, because it means the fitting is listed for grounding and bonding continuity across the joint. It also conforms to NEMA FB 1.
4) Will these couplings satisfy a Buy American / federal job spec?
Yes. The ERC couplings are made in the United States and carry Buy American Act compliance, plus ARRA compliance for federally funded work. They also reference Federal Specification A-A-50553, which is the spec line a government or institutional submittal usually asks for.
5) Compression or set screw coupling for a 3 inch EMT run, which should I use?
The ERC is a compression coupling, which makes up with a gland nut and ring rather than a set screw biting the wall of the tube. On larger raceway like 2-1/2 through 4 inch that gives you a more consistent mechanical and electrical joint, and the UL 467 listing backs the grounding path. Set screw couplings are generally the cheaper dry-location choice; go compression where you want the tighter joint or where the run is doing double duty as the ground path.
6) Do I need to thread the conduit ends before installing these couplings?
No threading. The compression design clamps onto a square-cut, reamed conduit end, so you can join rigid without cutting threads in the field. Cut clean, ream the burr, seat the tube fully into the coupling body, then tighten the compression nuts on both sides.
7) What part number do I order for a 4 inch dual-rated compression coupling from American Fittings?
ERC400CPLG is the 4 inch. Stepping down: ERC350CPLG for 3-1/2 inch, ERC300CPLG for 3 inch, ERC250CPLG for 2-1/2 inch. Same steel body and same compression connection across all four.
8) Are these ERC couplings RoHS and Prop 65 compliant for our submittal package?
They cover the full environmental sheet: RoHS compliant, REACH compliant, California Prop 65 compliant, and Conflict Minerals certified. For a healthcare, education or government submittal that is normally the whole checklist in one line.
