Blackburn 31217 – Frequently Asked Questions
1) What size pipe or ground rod does the Blackburn 31217 ground clamp fit?
The 31217 is a 1 inch straight ground clamp, so it is sized for 1 inch pipe. Straight-body clamps like this one wrap the pipe and take the grounding conductor in line, which is what you want on a straight run of water pipe or conduit rather than a bent or offset approach.
2) What wire sizes will the Blackburn 31217 ground clamp accept?
It is rated for 6-2 conductors, meaning it takes grounding electrode conductors from No. 6 AWG up through No. 2 AWG. If your bonding jumper is No. 4 or No. 6 copper, which covers most residential and light commercial services, this clamp handles it. For anything larger than 2 AWG you need a bigger clamp.
3) Is this a mechanical ground clamp or does it need to be crimped or exothermically welded?
Mechanical. The Blackburn 31217 is a mechanical connector, so it installs with a wrench or screwdriver on the clamp screw. No crimp tool, no compression die, no exothermic mold or powder. That is why electricians reach for it on service bonds and retrofits where you cannot bring a press or a welding kit to the pipe.
4) Is the Blackburn 31217 sold individually or in a box?
Sold each. One clamp per unit, so order the exact count you need for the job rather than a carton. The manufacturer part number to specify is 31217.
