Electrical Schematics for Campervan Systems

I've worked on a couple projects creating electrical schematics for campervans. Using AutoCAD Electrical I created professional-grade schematics detailing the installation (done by yours truly) and protection schemes of the system.

Here are parts of various AutoCAD Electrical diagrams I created as part of these projects.

See https://van.maroukis.net/06-electrical-systems for system diagrams, also included here

Annotated for description. The Victron 712 Smart BMV has a NO relay that drives the Blue Sea Systems ML-RBS Contura Switch "+12V to close" line (Brown wire). This relay is activated by an undervoltage condition and is a last-stop measure to protect the batteries from being over discharged.
