Believe it or not, the BSP for Canada also provided for hard-wired power connections to KSUs. I only remember references to versions of the 550/551 having such an option.

I can say with complete certainty that I never saw anything like this, but apparently there was such a requirement. My guess is that this was yet another of those crazy Canadian things that is no longer required on any system.
