I am in the middle of the build an electrical system for my van using REC BMS, LifePo4 cells, and Victron equipment. I have a question regarding placement of the main fuse. Rec BMS (and few other users I could find example builds) shows the main fuse from the positive side located after the main contractor?
There is a discussion started on the solar forum where few users commenting this is wrong and that the fuse should be first in the connection from the battery. Here is a link to the post:

It would be great to know what is the reason for the main fuse to be located after the contractor. And if it make any difference for the pre-charge process placing it just of the Battery+ post, as I understand it pulls a high-amp draw? Would that possibly blow a 400A fuse?
I would greatly appreciate a clarification, last thing I want is to accidentally destroy the contractor by a surge in mid of traveling somewhere off-grid. Thank you kindly.
