Torque Guidelines for Victron Energy and Blue Sea Equipment
When wiring up your electrical system, it’s super important to make sure that you have solid crimps on your lugs/connectors and that, when you connect them up to the terminals on your equipment they are tight. Bad crimps or loose lugs can create resistance, which can result in excessive and dangerous heat. On the other hand, you don’t want to overtighten connection points to the point where you risk breaking something.
This post details the specific torque guidelines for commonly used Victron Energy and Blue Sea equipment. If you don’t already have one, we recommend this torque wrench that you can pair up with any standard socket set and this tool for torquing screw terminals.
If you’ve never used a torque wrench, this is a pretty good video about how they work.
