Blackburn GUV11821 – Frequently Asked Questions
1) What conductor size range does the Blackburn GUV11821 ground clamp take?
The GUV11821 U-bolt ground clamp is sized for 250 kcmil down to 2/0 conductor. If your grounding electrode conductor falls outside that band, you need a different clamp in the U-bolt range rather than forcing this one onto an undersized or oversized cable.
2) Is the Blackburn GUV11821 U-bolt clamp UL listed for grounding?
It carries UL E3060 and CSA 12798. That is the file coverage an inspector or an institutional spec typically wants to see on a grounding connector, and the CSA reference means it can be used on work north of the border as well.
3) Can I use this U-bolt ground clamp with copper conductor?
Copper is the conductor material this clamp is built for. Pair it with copper grounding electrode conductor in the 250 kcmil to 2/0 range; do not substitute aluminum cable into a connector rated for copper.
4) How much room do I need to mount a Blackburn GUV11821 ground clamp?
Allow for a 3-15/16 inch overall length on the clamp body. On a congested rack, ground bar, or pipe run, that is the clearance to check before you commit the location, since the U-bolt has to seat and the nuts have to be reachable with a wrench.
5) What is the difference between a U-bolt ground clamp and a standard pipe ground clamp?
A U-bolt style clamp like the GUV11821 pulls the conductor down against a saddle with a threaded U-bolt and two nuts, which suits heavy conductor in the 250 kcmil to 2/0 range where a small screw-type pipe clamp will not get enough bearing. A conventional strap or pipe ground clamp is the better choice for smaller grounding electrode conductor on water pipe or rod.
6) Is the GUV11821 sold individually or in a box?
Sold each. Order the exact count you need for the job rather than buying to a carton quantity.
7) Where is the Blackburn GUV11821 ground clamp made?
Country of origin is India. That matters if you are bidding public work with domestic sourcing language in the spec, so check the requirement before you submit it on a government job.
