Blackburn 50LC – Frequently Asked Questions
1) What is the Blackburn 50LC coupling used for on a ground rod?
The Blackburn 50LC is a silicon bronze coupling for joining 1/2 inch ground rods end to end when one rod will not reach the required depth. It threads 9/16-12UNS, which is the thread the rod ends are cut to, so the two rod sections draw together inside the coupling and stay electrically continuous.
2) Why silicon bronze instead of steel for a ground rod coupling?
Silicon bronze is used because the coupling sits in permanently damp soil alongside a copper-bonded rod. Bronze resists the galvanic corrosion you get pairing dissimilar metals with copper, and the 50LC is classed as a copper conductor material part, so the joint stays low resistance for the life of the electrode.
3) How is the Blackburn 50LC sold, individually or in a bag?
Each. One 50LC coupling per selling unit, so you order the count you need. Remember a three-section rod run takes two couplings, and if you are driving with a rotary hammer you also need a driving stud to protect the top threads.
4) Does the 50LC coupling come insulated or with any covering?
No insulation or covering. It is a bare bronze threaded coupling intended for direct burial contact with the earth, which is what a grounding electrode connection requires.
