Milbank 1010GCU – Frequently Asked Questions

1) What sizes does the Milbank GCU wireway universal connector come in?
The GCU universal connector is offered in six square cross sections to match standard wireway trough sizes: 2.5x2.5 (22GCU), 4x4 (44GCU), 6x6 (66GCU), 8x8 (88GCU), 10x10 (1010GCU) and 12x12 (1212GCU). Order the one that matches the cross section of the trough you are joining, since the fitting bolts between like-sized wireway sections.
2) Can I use a Milbank GCU connector outdoors or in a wash-down area?
No. The GCU is a NEMA Type 1 indoor fitting, which means it guards against incidental contact with the enclosed conductors but offers no rated protection against rain, dust or hose-down water. Keep it inside a dry, protected building space. For exterior runs or damp locations you need a rain-tight NEMA 3R wireway and matching 3R fittings instead.
3) Is the Milbank GCU connector UL Listed for a commercial inspection?
Yes, the GCU wireway connector is UL Listed, which is what an inspector looks for on a Type 1 raceway fitting in commercial distribution work.
4) What does a wireway universal connector actually do, and when do I need one instead of a coupler?
A universal connector is the transition fitting between wireway sections or between a wireway and an enclosure, used where a plain straight coupler will not make the joint. The GCU carries the wire through and keeps the raceway enclosed and bonded as one continuous system. If you are simply butting two straight troughs end to end in line, a standard coupler does that job; the universal connector is what you reach for when the connection is not a simple inline splice.
5) Does the Milbank GCU come with knockouts for conduit?
No knockouts. The GCU ships as a blank fitting, so there are no factory conduit openings to punch out. Any penetration has to be field-drilled or punched with a hole saw or knockout punch, and you supply the connector or fitting for it.
6) Does ordering a GCU get me the mounting hardware and the wireway itself?
What you get is the fitting alone. The GCU consists of the connector body and its screw cover; the wireway troughs, hangers, straps, and any conduit connectors are separate line items. Size the fitting to your trough cross section and add the trough and support hardware to the same order so the run is complete.
7) Will a galvanized steel wireway fitting hold up in an unheated warehouse or parking garage?
G90 galvanized steel gives good corrosion resistance for interior service, including unheated but covered spaces. The limit is the NEMA Type 1 rating, not the metal: an open parking garage is a wet location, and a Type 1 fitting is not rated for it. Dry, covered industrial and warehouse interiors are where this one belongs.
8) How is the cover on the Milbank GCU fitting secured?
Screw cover. The cover fastens down with screws rather than a hinge and latch, so it stays closed in a trafficked area and still comes off for pulling or re-pulling conductors. Plan on access room in front of the fitting and a screwdriver on hand at service time.
9) I need a UNSPSC code for the Milbank GCU to set it up in our purchasing system.
The GCU wireway universal connector is classified under UNSPSC 39131711. Useful if you are loading it into a procurement catalog or a government or institutional purchasing system that requires a commodity code on the line.
