Ground and heat shrink

I called the supplier to tell him that the heat shrink on the cable was too short.

You can see where my finger is that the wire shows. The bend is close but it is not enough to cause this in my opinion.

The supplier did  send a piece of heat shrink, I will add a piece with the new cable for the chassis ground of the charger inverter.

  1-18 AWG black 14 foot 3/8 for the 600 amp bus and none on the other end.

The naked end will get striped and the cable put in a set screw. I think it is a little long but I can cut it off to fit it.
