Summary

• All components design within fuse box are
  defined.
• Max current draw per HV line is 1,253uA
• Max number of straws per HV line is 96 (192 ch)
• Yet to be defined components outside the fuse
  box
• HV connector at PPB1
• Fuse box ground connection at cooling plate or
  roof board
• Parts are being quoted for manufacture, expect to
  start production
• Fuse size can impact fuse box dimension. If its
  different from 2001 prototype we need to know
  ASAP.
