Blackburn GUV4025 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GUV4025 ground clamp take?
The GUV4025 U-bolt ground clamp covers a conductor range of 250 kcmil down to 2/0, and it is rated for copper conductor. If your grounding electrode conductor is smaller than 2/0, you want a different clamp in the range.
2) Is the Blackburn GUV4025 UL listed for grounding?
It carries UL E3060 and CSA 12798 listings, which is what an inspector will look for on a grounding electrode connection. Those are the standards published for this U-bolt clamp.
3) Can I use the GUV4025 U-bolt clamp on aluminum conductor?
No. The GUV4025 is specified for copper conductor only. For aluminum or copper-clad aluminum grounding conductors you need a clamp rated AL/CU, otherwise you risk a dissimilar-metal connection the inspector will reject.
4) How much room do I need around the pipe or rod to install a GUV4025 ground clamp?
Allow for the clamp's 6-5/16 inch net length when you lay out the connection. U-bolt style clamps wrap the electrode and tighten against a saddle, so you need clearance on both sides to get the nuts on and a wrench swing to torque them.
5) What is the difference between a U-bolt ground clamp and a standard pipe ground clamp?
A U-bolt type like the GUV4025 loops a threaded U around the electrode and draws it down onto a body that holds the conductor, so it grips over a wider spread of electrode diameters and takes heavy conductor, here 250 kcmil to 2/0 copper. A one-piece strap or bronze pipe clamp is sized to a specific pipe size and generally handles smaller conductor. Use the U-bolt where the electrode size varies or the conductor is large.
6) Is the Blackburn GUV4025 sold individually or in a box?
It is sold each, one clamp per unit, under manufacturer part number GUV4025. Order one per grounding connection you are making.
