Step Up to 24 Termination Positions
When 12 or 18 positions won't provide enough capacity, the NB-24 offers a logical step up. It accommodates 24 termination points while remaining substantially shorter than the 36 and 48 hole products in the same range.
The bar is rated at 165A and each hole is specified at 10mm². Its two M8 bolts are supplied with spring washers. Together, these confirmed specifications make it easier to compare the product against the connection count, conductors and available space identified in the electrical design.
Useful Capacity Without Selecting the Longest Bar
At 233mm long, the NB-24 may suit assemblies that need a greater number of earth or neutral terminations but don't have the space or need for a 316mm or 440mm bar. It also provides six more holes than the NB-18, allowing buyers to select the closest practical match rather than automatically choosing the largest model.
Check the internal dimensions of the assembly before ordering. Space must be available not only for the 233mm bar but also for its mounting arrangement, conductor entry and ongoing access.
The product can be configured for earth or neutral termination. Any mounting supports, insulation or other installation accessories required will depend on the intended use and aren't specified as included in Tesla's product data.
Q: What is the current rating of the Tesla NB-24?
A: Tesla rates the NB-24 at 165A. The rating must be considered alongside the other requirements of the electrical design.

A: Yes. The product has 24 holes, each specified at 10mm².
Q: How much longer is the NB-24 than the NB-18?
