Wire Size and Temperature Rating
Cables connecting the HBA
to the 24V batteries must be sufficiently sized to prevent unwanted voltage
drop. The temperature rating of the wire should be a minimum of 90ºC.
Vanner recommends the following wire and fuse sizes for the 250A and 300A HBA's. To protect the
positive cable, it shall be fused as close to the 24V battery as practical.

* The Panduit part number listed is recommended, not required, by Vanner. Equivalent substitutes may
be used. Contact Vanner engineering for a drawing of the Panduit ring terminal.
The recommended terminal is a right angle lug that enables the installer to route the 4/0 cables along the
side of the HBA. Factory installed tie wrap bases are present on the side of the HBA for strain relief.
Crimp the ring terminals using
Panduit CT-930
manual/hydraulic crimping tool.
