Blackburn GTC24 – Frequently Asked Questions
1) What conductor size range does the Blackburn GTC24 tower ground clamp accept?
The GTC24 tower ground clamp takes conductors from 2/0 minimum up to 250 kcmil maximum. Anything smaller than 2/0 will not seat properly in the jaw, and anything above 250 kcmil will not fit, so size the run to that window before you order.
2) Is the Blackburn GTC24 ground clamp copper, and can I use it with aluminum conductor?
The GTC24 is a copper conductor-material clamp. Use it on copper grounding conductors; pairing copper hardware with aluminum conductor introduces a dissimilar-metal connection, so specify a clamp rated for aluminum or a dual-rated AL/CU connector if your run is aluminum.
3) Is the GTC24 tower ground clamp insulated?
No. The GTC24 is a non-insulated mechanical grounding clamp, bare metal at the connection. If the installation needs the tap covered, plan on a separate boot or cover, or field-apply tape or heat shrink per your site spec.
4) How much space does the Blackburn GTC24 clamp need on the tower leg?
Allow for a net depth/length of 1-15/16 inches for the GTC24 body. That is the working clearance to check against adjacent steel, flange bolts, or a crowded leg joint before you commit to a mounting point.
5) Is the GTC24 a compression connector or a bolted clamp?
It is a mechanical grounding connector, not a compression lug, so it is torqued down with a wrench rather than crimped with a hydraulic tool. That matters on tower work where you want a connection you can inspect and re-torque without cutting the conductor.
6) Does the Blackburn GTC24 ship as a single clamp or in a box quantity?
The GTC24 is sold each, one clamp per unit. Tower grounding jobs usually need several per structure, so count your leg and ice-bridge connections and order the quantity outright.
7) What is the manufacturer part number for the Blackburn tower ground clamp rated 2/0 to 250?
Blackburn part number GTC24. That is the number to quote for the tower ground clamp covering 2/0 minimum through 250 kcmil maximum copper.
