Blackburn GTC13 – Frequently Asked Questions
1) What wire sizes does the Blackburn GTC13 tower ground clamp accept?
The GTC13 takes grounding conductor from No. 4 AWG at the small end up to 2/0 AWG at the large end. Anything smaller than No. 4 or larger than 2/0 needs a different clamp, since the conductor has to seat properly in the channel for the connection to hold under torque.
2) Is the Blackburn GTC13 ground clamp insulated?
No. The GTC13 is a non-insulated mechanical grounding clamp, so the metal body is part of the current path and bonds directly to the steel it is bolted to. If your spec calls for an insulated or covered connector, this is not it.
3) What is a tower ground clamp used for versus a pipe or rod ground clamp?
A tower ground clamp like the GTC13 is made to bond a grounding conductor to structural steel, tower legs, and angle or flat members. Pipe and rod clamps are shaped to wrap a round surface, so they are what you want on a water pipe or a driven ground rod. Pick by the surface you are landing on, not by conductor size alone.
4) How deep is the Blackburn GTC13 clamp body?
Net depth on the GTC13 is 1-21/32 inches. Worth checking if you are working inside a tight tower leg flange or behind other mounted gear where clearance for a wrench is limited.
5) Is the Blackburn GTC13 sold individually or in a bag quantity?
It ships as an each, so one clamp per unit ordered. Order one per bonding point rather than expecting a multi-pack.
6) What is the exact manufacturer part number and country of origin for the Blackburn tower ground clamp?
Manufacturer part number is GTC13, from Blackburn, made in India. Useful if you are matching a submittal or standardizing clamps across a tower site.
