Eaton CUGROUND – Frequently Asked Questions

1) Will the Eaton CUGROUND ground bar fit a Pow-R-Line PRL1A or PRL2A panelboard?
That's exactly what the CUGROUND copper ground bus assembly is built for. Eaton lists it for PRL1A/2A panelboards in the 42-48 circuit range, so it drops into Pow-R-Xpress PRL1A and PRL2A interiors of that size. If your panel interior is a different Eaton series, or a smaller circuit count, it is the wrong kit.
2) How many circuits does the Eaton CUGROUND ground bus assembly cover?
It covers panelboard interiors in the 42 to 48 circuit range, and Eaton rates the bar itself at 42 circuits. For a 24 or 30 circuit PRL1A interior you want the smaller ground bar kit for that circuit count, not this one.
3) Is the Eaton copper ground bus assembly UL Listed for a commercial panelboard job?
Yes, the CUGROUND copper ground bus assembly is UL Listed. That is the line an inspector or a spec reviewer on a commercial or institutional job looks for when you add a ground bar to a panelboard interior.
4) Do I need a separate ground bar in a PRL1A panelboard, or is one already in there?
Panelboard interiors are commonly shipped without a ground bar, and it is ordered as a kit like the Eaton CUGROUND. You need a separate equipment ground bar any time the panel is a subpanel, where grounded (neutral) and grounding conductors must stay isolated from each other, and on any feeder-fed panel downstream of the service. At the service disconnect the neutral can be bonded, so a separate bar is not always required there. For a 42-48 circuit PRL1A/2A interior, the CUGROUND is the copper bar Eaton lists for it.
5) How much room do I need in the panel gutter for the Eaton CUGROUND ground bar?
Plan on a 14 inch run for the assembly, with 2 inch height and 2 inch width. It mounts along the gutter of the panel interior, so measure your available gutter length before ordering; on a 42-48 circuit PRL1A/2A interior there is room for it by design.
6) Is the Eaton CUGROUND bar solid copper or aluminum?
Copper. Eaton designates it CU GROUND, which is the copper ground bus version. That matters if your specification or local amendment calls for copper grounding conductors landed on a copper bar, and it matters for dissimilar-metal concerns when you are terminating copper equipment grounding conductors.
7) What is the Eaton part number for the 42-48 circuit copper ground bar?
CUGROUND is the Eaton catalog number, described as the copper ground bus assembly for PRL1A/2A panelboards, 42-48 circuit. Order it by that number and specify the panelboard it is going into so the circuit range matches.
8) Is the Eaton CUGROUND ground bar a one-person install?
It weighs 4 pounds and runs 14 inches, so it's a single-hand piece to set into the gutter and fasten. The work is mounting the bar to the interior and landing conductors, not wrestling the part.
