I’m familiar with the mounting requirements of this unit… I considered a NEMA enclosure as well.
I was just curious why people would opt for a 12 circuit dual buss panel in addition to the switch pro (just making sure others understand it’s not required).
I don’t have THAT many aux circuits in the truck, but those that might require always on I would consider just running those through the SP as well and program it accordingly. The main reason being that you would not require a separate external LVD like the BlueSea m-LVD I am currently using for battery protection and separate switches.
True, there are certain loads I would not want fed enough the 9100, so, I could understand wanting another panel. That said, instead of the ST Blade 12, I would consider the smaller 6 circuit, or better yet the Safety Hub.
If you built a tray that can accommodate the SafteyHub 100 or 150, it would be a nice combo as you can protect much larger loads in a convenient manner. Just a thought.
