RAB CU4A – Frequently Asked Questions

1) What finishes does the RAB CU4 4-hole universal cover come in, and what are the part numbers?
Five finishes, each with its own catalog number: CU4 in gray, CU4A in bronze, CU4B in black, CU4VG in verde green, and CU4W in white. The base CU4 is the gray one, so if you are matching existing gray fixtures on a site, order CU4 and not one of the suffixed numbers. The suffix is the only thing that changes between them.
2) Is the RAB CU4 rated for high voltage work?
It carries a 35 kV voltage rating, which puts it in utility and power distribution territory rather than ordinary 600 V branch circuit work. If your application is a standard commercial lighting or receptacle circuit, the rating is well beyond what you need, and that is not a problem, but it is worth confirming the rating matches the class of conductor you are terminating.
3) Is the RAB CU4 UL listed? Our facility spec requires listed connectors.
Yes, it is listed under UL file E9809. For an institutional or government submittal, that file number is what the inspector or spec reviewer will want to see referenced.
4) Will the RAB CU4 hold up outdoors without corroding?
It is copper, tin plated for corrosion resistance, which is the standard treatment for connectors that sit in weather-exposed or damp locations. Tin plating also helps where the connection sees dissimilar metals or moisture at the interface. Copper base material means high conductivity from seamless copper tubing.
5) Whose product is the CU4 really? I see RAB and Blackburn both referenced.
The brand label on the part is Color Keyed / Blackburn, with Blackburn as the sub brand. Country of origin is Mexico. If your purchasing system or submittal package lists the line as Blackburn, the CU4 is the same item.
6) Is the CU4 sold individually or in a box?
Selling unit is each, so you are buying one piece per unit ordered. Count your terminations and order to that number rather than assuming a carton quantity.
