Blackburn GUV13821 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GUV13821 ground clamp take?
The GUV13821 U-bolt ground clamp is rated for conductors from 2/0 through 4 AWG, so it covers the common grounding electrode conductor range on residential and light commercial services. If your run is larger than 2/0 or smaller than 4 AWG, this is the wrong clamp.
2) Can I use the GUV13821 with aluminum grounding conductor or only copper?
Copper. The conductor material for the GUV13821 is listed as copper, so spec it for copper grounding electrode conductors rather than aluminum.
3) Is the Blackburn GUV13821 ground clamp UL listed for inspection?
It carries UL E3060 and CSA 12798 listings, which is what an inspector looks for on a grounding electrode connection and what lets the same part be used on Canadian jobs.
4) How big is the GUV13821 U-bolt clamp, and will it clear a tight meter base or panel knockout area?
The clamp measures 3-7/16 in on its net depth/length dimension. That is the figure to check against your available clearance around a ground rod, water pipe, or rebar stub before you commit to it in a congested enclosure or trench box.
5) What is a U-bolt ground clamp used for versus a strap-type or acorn clamp?
A U-bolt style clamp like the GUV13821 wraps the electrode with a bolt yoke and clamps the conductor under a pressure bar, which suits round electrodes such as ground rods and pipe where you need a solid mechanical bite on a heavy 2/0 to 4 AWG copper conductor. A flat strap or armored ground clamp is the choice when you are landing on a water pipe with a wide contact band, and a small acorn clamp is for lighter conductors on a driven rod. Match the clamp to both the electrode shape and the conductor size.
6) Is the GUV13821 sold individually or in a box of clamps?
Sold each. If you are standardizing grounding hardware across a portfolio of buildings or stocking an MRO crib, order the quantity you need unit by unit rather than expecting a carton count.
7) Where is the Blackburn GUV13821 made?
Country of origin on the GUV13821 is India. That is the detail government and institutional buyers with domestic-sourcing requirements need to confirm before it goes on a submittal.
