Why / What / Where?

Need a proposed design for a simple fuse block. A fuse block mechanically constrains the terminals of the fuse to the battery box enclosure.

There is 1 pair of conductors (high voltage (HV) and ground (GND)) exiting the battery pack, and multiple devices that need to connect to this high voltage connector:

1. Left Motor Controller

2. Right Motor Controller

3. Solar Enclosure (to solar sense boards)

4. Charger (Elcon charger output)

5. Pre-charge

6. DC-DC

These connections must all be fused according to regulation 8.5.B below.

So we need some way of splitting the 1 battery box output connector out to multiple connections with various sizes of wire gauge. This is the purpose of a power distribution unit, which typically incorporates all the fuses as well.
