Blackburn JJR – Frequently Asked Questions
1) Is the Blackburn JJR ground clamp bronze, and can it go on a copper water pipe?
Bronze construction. Bronze on copper pipe is the normal pairing for a grounding electrode connection because the two metals sit close together galvanically, which is why bronze clamps are the standard choice for copper water pipe bonding rather than a plated steel clamp.
2) What is the exact part number to order this Blackburn pipe ground clamp?
Order it as Blackburn JJR. That is the manufacturer part number for the bronze pipe ground clamp covering 1/2 inch to 1 inch pipe. Country of origin is India.
3) Is a pipe ground clamp like the Blackburn JJR the right choice, or do I need a ground rod clamp?
A pipe clamp such as the JJR wraps a round pipe between 1/2 and 1 inch and is used where the grounding electrode is metal water pipe or where you are bonding conduit. If your electrode is a driven ground rod, use a rod clamp sized to the rod diameter instead, and for bonding to structural steel or a plate you want a lug or a bonding connector rather than a pipe clamp.
4) Is the Blackburn JJR clamp insulated?
No insulation on it. It is a bare bronze grounding clamp, which is what you want on a grounding electrode conductor connection since the metal-to-metal contact is the whole point of the joint.
5) Do I get one clamp or a box when I order a Blackburn JJR?
The JJR is sold each, one clamp per unit. If you are grounding a run of units or standardizing a maintenance stock, order the quantity you need piece by piece.
