Blackburn G4-1 – Frequently Asked Questions
1) What is the exact part number to order for the Blackburn 1/2 inch ground rod clamp?
Order it as Blackburn G4-1. That is the manufacturer part number for the 1/2 inch ground rod clamp, and it is sold individually rather than in a carton or bag quantity.
2) What is a ground rod clamp used for on an electrical service?
It is the mechanical connection between the grounding electrode conductor and the driven ground rod. The G4-1 clamps onto a 1/2 inch rod and holds the conductor against it, which is the alternative to an exothermic weld or a compression connection. Electricians use it at service entrances, and it is also what gets used on antenna, generator, and equipment grounding electrodes.
3) Is the Blackburn G4-1 ground rod clamp made in the USA?
Yes, country of origin on the G4-1 is the United States. That matters on public work and institutional jobs where domestic-sourcing language shows up in the specification, and it is the kind of detail a procurement officer asks for in writing before releasing a PO.
4) Do I get one clamp or a box when I buy the Blackburn G4-1?
One clamp. The G4-1 is sold each, so if you are grounding several services or running multiple rods on a site, order a piece for every rod-to-conductor connection you need to make.
