Bridgeport Fittings RB-17 – Frequently Asked Questions

1) Can these Bridgeport bronze clamps be used on rebar in a concrete-encased electrode, or only on water pipe?
Both. The RB-16 and RB-17 clamps are listed for 3/8 inch to 1 inch rebar as well as 1/2 inch to 1 inch ground water pipe, which is what makes them usable for a Ufer/concrete-encased electrode connection as well as a water service bond.
2) What size grounding conductor will the lay-in lug on the Bridgeport RB clamps accept?
The integral lay-in lug takes #10 solid through #2 stranded copper. If your grounding electrode conductor is larger than #2, this clamp body will not land it.
3) Is this ground clamp approved for burying in soil or encasing in concrete?
Yes, it is a direct burial type clamp. The bronze body runs a minimum of 80 percent copper for corrosion resistance underground, it carries a NEMA FB-1 rating, and it is covered under UL File E20412.
4) What is the difference between the Bridgeport RB-16 and RB-17 ground clamps?
Both models share the same working range: 1/2 inch to 1 inch water pipe, 3/8 inch to 1 inch rebar, and a lay-in lug rated #10 solid to #2 stranded. Order by the model number your spec or submittal calls out, since the pipe, rebar and conductor capacities match.
5) Why choose a lay-in lug ground clamp instead of a standard setscrew ground clamp?
A lay-in lug lets you drop the grounding electrode conductor into the lug and tighten it, rather than threading the wire through a closed hole. In a trench or a footing where the conductor is already run and stiff, that is the difference between making the connection and cutting the wire. The RB clamps have the lug cast into the body, so there is no separate lug to order.
6) How much space does the Bridgeport RB ground clamp take up on the pipe?
It is a compact body at 2.25 inches long and 1.625 inches wide, so it fits where a water service enters a wall or where rebar is tight in a footing cage. The finish is as cast bronze, no plating to wear off in the ground.
