Blackburn 3902BU – Frequently Asked Questions
1) Can I use a bronze ground clamp directly on copper water pipe without corrosion problems?
Yes. The 3902BU is bronze throughout the conducting body, which is the standard pairing with copper water pipe because the two metals are close enough on the galvanic scale to avoid the accelerated corrosion you get from dissimilar-metal contact. That is why bronze clamps are specified for copper water service bonding rather than plated steel.
2) Is the Blackburn 3902BU clamp insulated?
No insulation on it. The 3902BU is a bare bronze clamp, which is what you want on a grounding electrode connection where the point is continuous metal-to-metal contact between the grounding conductor and the pipe. If you need a covered or insulated connector, this is not that part.
3) Does the Blackburn 3902BU come in a multi-pack or is it sold singly?
Sold each. One 3902BU clamp per unit, part number 3902BU, so an electrician stocking a truck or a maintenance crew ordering for several services orders the quantity they need rather than a carton.
4) Where is the Blackburn 3902BU ground clamp made?
Made in the United States. That matters on federal, municipal and some institutional jobs carrying domestic-content requirements, where country of origin has to be documented on electrical fittings.
