In reading a lot of the threads here, I've come across several mentions of people wishing they had started off with a DIN rail setup and that they hope to transition to the same in a further iteration of their build. I come from an engineering background (Mining/Process,) and am fairly comfortable with the overall architecture, design and implementation of a traditional backplane install, but am completely unfamiliar with DIN rails.

Does anyone have a good source for a primer for understanding/transitioning to DIN rails? From what I've read, it would be a great option for us in terms of experimentation/adaption, but am having trouble finding source material to bring me up to speed on the cons and benefits of sourcing components for a DIN setup. Anyone have suggestions?

Thanks!

With a 240V system, each phase of the 240 should be 'broken' at the same time. A fuse would only open one of the phases.
Hope this helps.
