Tesla TB254 Busbar Stud Connector 25mm Short 14mm Pole Active or Neutral Switchboard

Description

Compact stud connector for tight boards.

Crowded switchboards leave little room behind the busbar for a full-length stud. The Tesla TB254 is the short version at 14 mm pole length, and it still takes cable up to 25 mm2 per connector on either active or neutral duty. One part number, both sides of the board.

Cable Capacity and Where It Sits

The published figure is a conductor capacity of up to 25 mm2 per connector. That is the ceiling rather than a fixed size, so smaller conductors are equally within scope. Tesla rates the same connector for active and for neutral connections, which means a single part number covers both sides rather than forcing two separate line items into your stock. On a mixed board that is one fewer item to count, and one fewer thing to get wrong at the bench. Because the connectors are supplied individually, order to the count your board actually needs.

Why the Short Pole Matters

Pole length on this unit is 14 mm. Tesla identifies the short version as the one intended for compact switchboards and tight panel layouts, where depth behind the busbar is the constraint rather than the cable itself. If your board has generous clearance, pole length is rarely the deciding factor. If it does not, a shorter pole is often what lets the termination sit properly without fouling the enclosure or forcing an awkward cable bend at the entry. The 14 mm figure refers to the pole itself, so measure the clearance you have behind the bar rather than the depth of the enclosure.

Typical Installations

Tesla lists this connector for use in residential, commercial and industrial switchboards, in distribution boards, and in power distribution systems generally. Two points worth settling before you order:

• That 25 mm2 covers the largest conductor you intend to land on it
• That the short 14 mm pole suits your busbar arrangement, rather than the longer option in the range

The product data sheet does not publish a current rating, a voltage rating, a conductor material or an applicable standard for this part, so those figures are not stated here. The revision on file is dated November 2025, and it is the latest sheet Tesla has issued for the stud connector range. If a specific rating has to be confirmed for a job, ask us and we will take it back to the supplier rather than guess.

What cable size does the Tesla TB254 take
It handles cables up to 25 mm2 per connector, which is the maximum conductor size published by Tesla for this part. Smaller conductors sit within that same limit.

Can the TB254 be used on a neutral as well as an active
Yes. Tesla lists the connector as suitable for both active and neutral connections, so the one part number covers either position on the board.

How long is the pole on the TB254
The pole length is 14 mm. This is the short version, which Tesla identifies as the option for compact switchboards and tight panel layouts, rather than boards with room to spare.
