Blackburn CC20C-56R – Frequently Asked Questions
1) Will the Blackburn CC20C-56R ground clamp fit a 5/8 inch or 3/4 inch ground rod?
Both. The CC20C-56R is built to take either a 5/8 inch or a 3/4 inch diameter ground rod, so one part covers the two rod sizes you see most often on residential and light commercial service grounds.
2) What size grounding electrode conductor does the Blackburn CC20C-56R clamp take?
It is rated to 2/0 conductor, so it covers the common grounding electrode conductor sizes up through 2/0 copper. If your service calls for larger than 2/0, you need a bigger clamp body.
3) Is the Blackburn CC20C-56R UL listed for grounding?
Yes. It carries UL file E3060, which is the listing inspectors look for on a grounding electrode connection.
4) Is the CC20C-56R ground rod clamp copper or bronze, and can I bury it?
The CC20C-56R is a copper-bodied ground clamp. Copper and bronze grounding clamps are the ones used for direct burial and concrete-encased electrode connections, versus plated steel or aluminum bodies which are not suited to soil contact.
5) What size wrench or driver do I need to tighten this Blackburn ground clamp?
The clamp uses a 3/8 inch bolt, so a 3/8 hardware socket or wrench is what you bring to the rod. Nothing else is needed to make the connection.
6) Is the Blackburn CC20C-56R sold individually or in a box?
It is sold each, so you order the exact count of clamps your job needs rather than a bag or carton quantity.
7) Where is the Blackburn CC20C-56R grounding clamp made?
Country of origin is Mexico. That matters if you are filing origin documentation on a government or institutional order.
