Balanced Capacity for Mid-Sized Requirements

The NB-18 sits between Tesla's compact 12 hole bar and the larger 24 hole model. Its six additional termination points make it useful when a 12 hole bar would leave insufficient capacity, while its 186mm length remains easier to accommodate than the longer options in the range.

Each of the 18 holes is specified at 10mm². This allows the connection count, conductor requirements and physical dimensions to be reviewed before the product is selected. The bar is rated at 165A and includes two M8 bolts with spring washers.

Plan for Current and Future Connections

Choosing the correct bar requires more than matching the number of existing conductors. Consider whether the electrical assembly needs spare termination positions for planned circuits, as well as the available internal length and cable-routing space.

Where exactly 12 positions are sufficient, the shorter NB-12 may make better use of a compact enclosure. Where additional capacity is required, the NB-18 adds six positions. The NB-24 is the next step up and provides a further six holes over a 233mm bar length.

The NB-18 can serve as an earth or neutral bar in a suitably designed assembly. Its final mounting method, separation and any insulation required should be determined by the intended function and installation design.

Q: What size conductors suit the holes in the NB-18?
A: Tesla specifies 18 x 10mm² holes. Confirm that this capacity suits the conductors and termination requirements of the installation.

Q: How long is the Tesla NB-18?
A: The brass bar is 186mm long. Allow suitable additional space for mounting and conductor access.

Q: Should I choose the NB-18 or NB-24?
