Topaz Lighting 620BP – Frequently Asked Questions

1) What pipe sizes does the Topaz 620BP ground clamp fit?
The Topaz 620BP bare wire ground clamp fits pipe or conduit from 1/2 inch up to 1 inch trade size. That covers the usual water pipe and conduit runs an electrician bonds to at a service. Anything larger than 1 inch needs a bigger clamp body.
2) What size grounding conductor can I land in the 620BP clamp?
It takes bare wire from #10 AWG up to #2 AWG. That spans the typical #8 and #6 grounding electrode conductors on residential services as well as heavier #4 and #2 runs on commercial work. If your electrode conductor is larger than #2, this clamp won't accept it.
3) Can I use the Topaz 620BP on insulated or stranded THHN ground wire?
It's built as a bare wire clamp, so the conductor seat is sized and intended for bare grounding conductor. If you're bonding with an insulated conductor, you'd strip it back at the clamp or choose a clamp specified for insulated wire instead.
4) Is a zinc die-cast ground clamp OK for outdoor or damp locations?
The 620BP body is zinc die-cast, which gives corrosion resistance for standard electrical environments. For direct burial or a ground rod in soil, electricians normally specify a clamp listed for direct burial rather than a general-purpose die-cast pipe clamp.
5) What's the difference between a bare wire pipe ground clamp like the 620BP and an acorn ground rod clamp?
Two different jobs. The 620BP wraps a 1/2 inch to 1 inch pipe or conduit and lands a bare conductor against it, which is what you use to bond to a metal water pipe or a conduit run. An acorn clamp is a bolted saddle sized to a ground rod diameter and is what goes on the driven electrode. Most services use both.
6) Can I use one Topaz 620BP clamp for both interior water pipe bonding and panel grounding?
Yes, provided the pipe or conduit is in the 1/2 to 1 inch range and the conductor is #10 through #2 bare. The same clamp is used for water pipe bonding, conduit and equipment bonding, and service equipment grounding, so a property manager or MRO buyer can stock one part across those tasks instead of several.
