Blackburn 31224 – Frequently Asked Questions
1) What pipe size does the Blackburn 31224 ground clamp fit?
The 31224 is sized for 1-1/2 inch copper tube, and it is the straight body version rather than an offset. If your water pipe or ground rod run is a different trade size, you need a different clamp in the series; the clamp jaw has no adjustment beyond the one pipe size it is cut for.
2) What wire sizes can I land in the Blackburn 31224 grounding clamp?
It takes grounding electrode conductors from 6 AWG through 2 AWG. Anything smaller than 6 or larger than 2 will not seat correctly in the conductor channel, so a 4/0 service bond needs a larger clamp.
3) Can I use the 31224 on a galvanized or steel water pipe instead of copper?
It is built as a copper tube clamp for 1-1/2 inch copper, and the copper body is intended to sit against copper. For a galvanized or steel pipe bond, use a clamp rated for that pipe material instead so you are not creating a dissimilar metal joint at the grounding electrode.
4) Is this a mechanical clamp or does it need exothermic welding?
It is a mechanical connector, bolted down with a set screw style clamp, so no welding, crimping, or special tooling is involved. A wrench or nut driver is all you need to torque it onto the tube.
5) Does the Blackburn 31224 come in a bag or is it sold one at a time?
Sold individually, one clamp per unit. If you are bonding several services or stocking a truck, order the quantity you need as separate pieces rather than expecting a multi-pack.
6) What is the manufacturer part number for this Blackburn copper tube ground clamp?
Blackburn part number 31224. Order or cross reference by that number; the description that goes with it is a copper ground clamp for 1-1/2 inch tube accepting 6 through 2 AWG, straight body.
