Description
Flat two pole busbar connection, 25mm2 capacity
Terminating heavy cable into a busbar arrangement is the point where a tidy board either holds together or turns into a mess of adaptors. The Tesla TB252 busbar stud connector takes cables up to 25mm2 per connector and carries a 32mm pole length, giving you room to work where reach and spacing matter.

Where the 25mm2 capacity earns its keep
Cable size is the first thing that catches installers out on busbar work. The TB252 accepts conductors up to 25mm2 per connector, so a single part number covers a broad span of submain and distribution terminations rather than forcing a change of hardware partway through a board build. Tesla builds the range around exactly that flexibility, so the connector suits a wide range of cable sizes in an electrical setup instead of pinning you to one conductor size.
The same connector suits both active and neutral duty. That versatility keeps the parts list short, keeps the board visually consistent, and means fewer part numbers to carry on the van or hold in the store room.
Why the 32mm pole length matters
The TB252 carries a 32mm pole, which is the longer of the two connectors in the Tesla stud connector data sheet. That extra length is there for installations requiring extended reach or additional spacing, where the busbar sits further back from the termination point or where you need clearance between adjacent connections.
Getting this choice right at the design stage saves rework. Where the geometry is generous, the longer pole gives you the reach without strain on the conductor.
Australian switchboard applications
Tesla lists the stud connector range for residential, commercial and industrial switchboards, distribution boards, and power distribution systems. That covers the bulk of everyday Australian board work, from a domestic rebuild through to distribution gear on a commercial site, and it means the same connector carries across a contractor's typical mix of jobs.
Electrotraders supplies the TB252 as a single unit rather than a bulk pack, so you can order the exact count a board needs. For a switchboard upgrade where the connector count is known up front, that keeps the material order clean and avoids leftover stock sitting in the van.
What cable size does the Tesla TB252 busbar stud connector accept?
The TB252 accepts cables up to 25mm2 per connector, as published in the Tesla stud connector data sheet. That single figure covers a wide range of cable sizes in a typical switchboard installation.
Can the TB252 be used on both active and neutral connections?
Yes. Tesla states the connector is suitable for both active and neutral connections, so the same part number covers either duty in a switchboard, distribution board or power distribution system.
How long is the pole on the Tesla TB252?
The pole length is 32mm. Tesla describes this longer pole as suitable for installations requiring extended reach or additional spacing, which makes it the choice where the busbar sits further back from the termination point.
