Blackburn 3846 – Frequently Asked Questions
1) What ground rod sizes does the Blackburn 3846 ground clamp fit?
The Blackburn 3846 is built for ground rods from 1/2 inch through 1 inch diameter, so it covers the common 1/2, 5/8, and 3/4 inch rods used on services and the heavier 1 inch rod without swapping to a different clamp. One clamp part number for the whole range keeps a truck or a stockroom simpler.
2) Why choose a bronze ground rod clamp instead of a plated or zinc one?
Bronze is the material of choice where the clamp sits in soil against a copper-bonded rod and a copper conductor: it limits galvanic mismatch and holds up in wet earth better than zinc castings. The Blackburn 3846 is bronze, which is why it gets specified for buried rod connections rather than indoor-only uses.
3) Is the Blackburn 3846 ground clamp made in the USA for a government or institutional spec job?
Country of origin is the United States, which is what matters on Buy American and domestic-preference procurement for federal, municipal, education, and healthcare work. The part number to put on the submittal is Blackburn 3846.
4) What is the Blackburn 3846 actually used for on a service install?
It is a rod clamp: it terminates the grounding electrode conductor onto a driven ground rod at the electrode end, sized for 1/2 through 1 inch rod. It is not a water pipe clamp and not a bonding jumper fitting, so for bonding to metallic water pipe or conduit you want a pipe-style ground clamp instead.
5) Is the Blackburn 3846 sold individually or in a box?
It is sold each, one clamp per unit, under manufacturer part number 3846. Order the quantity you need rod by rod rather than buying a carton.
