Blackburn 70CNT – Frequently Asked Questions
1) What size ground rod does the Blackburn 70CNT coupling fit?
The 70CNT is a 3/4 inch rod coupling, so it is sized for 3/4 inch diameter ground rods. It will not take 1/2 inch or 5/8 inch rod, which are the other common sizes on the job, so match the coupling to the rod diameter you are actually driving.
2) Can I use the 70CNT to splice two ground rods together to hit required electrode depth?
That is exactly what a rod coupling does. The 70CNT joins one 3/4 inch rod to the next so you can drive deeper where soil conditions or the inspector require more length than a single rod gives you. Use one coupling per joint.
3) What is the exact manufacturer part number for the Blackburn 3/4 inch threadless rod coupling?
Blackburn part number 70CNT. Country of origin is India. Ask for it by that number to avoid being sent the threaded version or a smaller rod size.
4) Will the 70CNT coupling work as a ground rod clamp for attaching my grounding conductor?
No. The 70CNT couples rod to rod; it is not a conductor connector. To land a grounding electrode conductor on the rod you need a separate ground rod clamp sized for 3/4 inch rod and for your conductor gauge.
5) Is the Blackburn 70CNT sold individually or in a box?
It is sold each, so one coupling per unit ordered. Count one for every rod-to-rod joint in the run and order accordingly.
