Blackburn 3903 – Frequently Asked Questions

1) Is a bronze ground clamp the right choice for a copper water pipe, or should I use a different material?
Bronze is the correct pairing with copper pipe and copper conductor. The 3903's conductor material is bronze, which is copper based, so you avoid the dissimilar metal corrosion you would risk putting a galvanized or aluminum body on a copper line. In a damp basement or a meter pit, that matters more than anything else about the clamp.
2) Does the Blackburn 3903 water pipe ground clamp come insulated?
No insulation on it. The 3903 is a bare bronze mechanical clamp, conductor to pipe, with no insulating sleeve or coating. That is normal for a grounding electrode connection, where you want metal to metal contact, but it means the connection needs to be accessible and kept clean rather than buried in a wall.
3) Do I get one clamp or a pack when I order Blackburn 3903?
It sells each, one clamp per unit. For a service with a bond around the water meter you will want two, one on each side, plus one more if you are also bonding the hot water side or a gas line where the local code calls for it.
4) Is the Blackburn 3903 ground clamp made in the USA?
Yes, the 3903 is manufactured in the United States. That is the answer for government, school district, and other institutional work carrying a domestic sourcing requirement on the spec.
