Blackburn 3903BU – Frequently Asked Questions
1) Is the Blackburn 3903BU clamp bronze, and can it go on a copper water pipe?
The conductor body is bronze, which is the standard material pairing for bonding to copper water piping without setting up a dissimilar-metal problem. It is a non-insulated clamp, so the metal-to-metal contact between clamp, pipe, and grounding conductor is the connection.
2) What does DIRECT mean on the Blackburn 3903BU ground clamp?
Direct burial rated. The 3903BU is suitable for concrete-encased or buried connections as well as above-grade work, which matters when the water pipe connection is below the slab or in a crawlspace that sees moisture.
3) What part number should I put on a purchase order for this water pipe ground clamp?
Specify Blackburn 3903BU. That is the manufacturer part number for the bronze, direct burial water pipe ground clamp covering 1-1/4 to 2 inch pipe.
4) Is the Blackburn 3903BU sold individually or in a box?
Sold each. Order one per pipe connection; there is no carton minimum bundled into the unit.
