Blackburn TTC3 – Frequently Asked Questions
1) What is the Blackburn TTC3 used for?
The TTC3 is a transformer tank ground connector, a mechanical grounding connector used to terminate a grounding conductor to a transformer tank or similar metal enclosure. The body is copper, and there is no insulation on it, so it lands bare on the tank pad and relies on the mechanical clamp for the connection rather than a crimp or exothermic weld.
2) Will a copper transformer tank ground connector work on an aluminum conductor?
The TTC3 is a copper-bodied connector, and copper-only grounding connectors are intended for copper conductors. For aluminum or a mixed copper-to-aluminum termination you want a connector marked AL9CU dual-rated, not a copper-only body, to avoid a dissimilar-metal joint at the ground.
3) Is the Blackburn TTC3 a mechanical connector or does it need a crimp tool?
Mechanical. No crimper, no die set, no torch. The TTC3 clamps the conductor with hardware, so an electrician can make the termination with hand tools, and it can be loosened and re-terminated if the ground lead has to be re-pulled during commissioning.
4) Where is the Blackburn TTC3 made? I have a domestic-sourcing requirement.
The TTC3 is manufactured in India. If your project carries a Buy American or domestic-content clause on electrical materials, this connector will not satisfy it and you will need a US-origin grounding connector instead.
5) Does the TTC3 come with any kind of visual or torque indicator?
No indicator of any kind on the TTC3. Tightening is by feel and by the installer's torque spec, so if your utility or facility standard requires a witness mark or torque-indicating hardware on grounding terminations you will need to document it another way.
6) Is the Blackburn TTC3 sold individually or in a box of connectors?
Sold each. The TTC3 ships as a single connector, model/MPN TTC3, so an MRO buyer standardizing on it for transformer grounding can order the exact count needed rather than a carton quantity.
