Topaz Lighting 1757 – Frequently Asked Questions

1) What is the difference between the Topaz 1756 and 1757 Kenny Clamp?
Conductor type is the only difference to specify. The Topaz Kenny Clamp comes in a Solid conductor version, part number 1756, and a Stranded conductor version, part number 1757. The stranded version covers 3/0 stranded down through 8 stranded. Pick the one that matches the grounding electrode conductor you are landing, because the clamp body is machined for that conductor form.
2) Will a Kenny Clamp fit a 1/2 inch knockout on a panelboard?
Yes. The Topaz 1756 Kenny Clamp is made for 1/2 inch knockouts, so it lands in a standard 1/2 inch KO on a panelboard, switchboard, transformer enclosure, or metallic conduit without an adapter or reducing washer.
3) What size grounding electrode conductor does the stranded Kenny Clamp take?
The stranded version, part 1757, accepts 3/0 stranded through 8 stranded conductors. That range covers the usual service entrance GEC sizes on residential through light commercial services in one part number.
4) Is the Topaz Kenny Clamp UL Listed for service entrance grounding?
The 1756 Kenny Clamp is UL Listed. It is built to bond a grounding electrode conductor to metallic conduit, panelboards, switchboards, and transformer enclosures, which is the service entrance and bonding work inspectors look at most closely.
5) Why use a brass Kenny Clamp instead of a steel grounding bushing or fitting?
The Topaz 1756 is fabricated entirely of brass, which holds up better against corrosion in damp or exposed service entrance locations and keeps a low resistance path at the connection. A Kenny Clamp also does a different job than a grounding bushing: it clamps the grounding electrode conductor itself into a 1/2 inch knockout to bond it to the metallic enclosure or raceway, rather than bonding a conduit end at a hub.
6) Can I use the Topaz Kenny Clamp on a transformer enclosure or only on conduit?
Both. The 1756 bonds to metallic conduit, panelboards, switchboards, and transformer enclosures, anywhere there is a 1/2 inch knockout to land it in. That makes it a single part to standardize across gear rooms and service equipment in a facility.
7) How many Kenny Clamps come in a box?
Topaz packs the 1756 Kenny Clamp 100 to a pack. For a contractor stocking a service truck or an MRO crib doing repeat service work, that is a bulk carton rather than a single-piece buy, so plan the order around the 100 count.
