Blackburn GUV784 – Frequently Asked Questions
1) What size ground rod does the Blackburn GUV784 clamp fit?
The GUV784 U-bolt ground clamp is sized for rods from 7/8 inch through 1 inch diameter. That covers the heavier rod sizes, so if you are terminating on a 1/2 inch or 5/8 inch rod (the common residential sizes) this is the wrong clamp and you need a smaller U-bolt body.
2) What conductor sizes will the GUV784 ground clamp accept?
It takes 8 AWG through 4 AWG grounding electrode conductor. Anything larger, like 2 AWG or 1/0, will not seat in this clamp's conductor channel, so step up to a larger range clamp for those runs.
3) Is the GUV784 ground clamp UL listed for an inspection?
It carries UL E3060 and CSA 12798. That is the paperwork an electrical inspector looks for on a grounding electrode connection, and the CSA file covers work on the Canadian side as well.
4) Is the Blackburn GUV784 clamp copper, and can I use it on a copper-bonded ground rod with copper wire?
The conductor-contact body is copper, so it pairs with bare copper grounding electrode conductor and copper-bonded rods without creating a dissimilar-metal connection at the termination.
5) Is a U-bolt ground clamp the right choice, or should I use a different style?
A U-bolt clamp bolts down over the rod and clamps the conductor under mechanical pressure, which is what you want on a driven rod you may need to inspect or re-terminate later. If the connection will be buried and permanent, or you are bonding to rebar or structural steel, an exothermic or compression connection is the usual alternative. For the GUV784 specifically, the rod has to be 7/8 to 1 inch and the conductor 8 to 4 AWG.
6) How much room do I need in the trench or ground rod access box for this clamp?
Plan on 2-3/4 inches of length for the clamp body. A U-bolt style clamp also needs clearance to get a wrench on the nuts, so tight hand holes and shallow inspection boxes are worth measuring before you commit.
7) Is the Blackburn GUV784 sold individually or in a box quantity?
Sold each, so you can order the exact count for the service or for truck stock rather than buying a full carton. Manufacturer part number is GUV784.
