Blackburn GUV3021 – Frequently Asked Questions
1) What wire sizes does the Blackburn GUV3021 ground clamp accept?
The GUV3021 U-bolt ground clamp takes conductors from 2/0 through 4 AWG, so it covers the common grounding electrode conductor sizes in that band on a single clamp. If your conductor is larger than 2/0 or smaller than 4 AWG, you need a different catalog number.
2) Is the Blackburn GUV3021 UL listed for grounding connections?
Yes. The clamp carries UL E3060 and CSA 12798, which is what an inspector or a facility spec will want to see on a grounding electrode connection.
3) Can I use a copper grounding conductor with the GUV3021, and is the clamp itself copper?
The conductor material for this clamp is copper, so it is intended for copper grounding electrode conductors on copper or copper-alloy water pipe. Pairing dissimilar metals at a grounding connection invites galvanic corrosion, so keep the conductor copper.
4) Is the GUV3021 ground clamp insulated?
No, there is no insulation on it. It is a bare metal grounding connector, which is normal for a bonding clamp on a water pipe or conduit run but means it should not be relied on for any insulating or isolating function.
5) Does the Blackburn GUV3021 come as a single clamp or in a box quantity?
It sells each, one complete U-bolt clamp per unit, so order the count you need for the job rather than a carton multiple.
6) Where is the Blackburn GUV3021 ground clamp made?
Country of origin is India. That matters on public and institutional work where domestic-sourcing language may apply to the bill of materials.
