Blackburn GTC14 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GTC14 tower ground clamp accept?
The GTC14 takes conductors from 2/0 minimum up to 250 kcmil maximum, so it covers the usual tower and structure grounding runs in that range. Anything smaller than 2/0 will not seat properly in the clamp body and needs a smaller clamp.
2) Will a GTC14 work for 4/0 tower ground wire?
Yes. 4/0 sits inside the GTC14 range of 2/0 through 250 kcmil, so it lands in the clamp without an adapter.
3) Is the Blackburn GTC14 ground clamp copper or aluminum?
Copper conductor material, and the clamp is supplied non-insulated. That makes it a direct-bury and exposed-connection style mechanical grounding clamp rather than an insulated terminal, so plan on it being a bare metal-to-metal connection.
4) How much room do I need to fit a GTC14 tower ground clamp on a member?
Allow for a net depth/length of 1-15/16 inches on the Blackburn GTC14. That is the figure to check against tight flange spacing or a crowded ground bar location before you commit to the mounting point.
5) Is the GTC14 a mechanical clamp or does it need exothermic welding?
It is a mechanical grounding connector, so the connection is made with hardware and hand tools rather than an exothermic weld mold and powder. For crews without welding kits on the tower, that is the practical advantage; where a permanent irreversible bond is specified, a mechanical clamp will not satisfy it.
6) Is the Blackburn GTC14 sold each or in a box of clamps?
Sold as each, one clamp per unit. If you are grounding several tower legs or downleads, order the count you need per connection point.
7) What is the manufacturer part number and country of origin for this Blackburn tower ground clamp?
Part number GTC14, made in India. Distributors ordering against a spec should quote GTC14 exactly, since Blackburn's grounding line uses closely numbered clamps for different conductor ranges.
