Relevant to what, you asked?

Well, for instance, the current at the input is relevant to me as I want to have some idea of how much current the whole system is likely to draw in total when at full blast, including 3 servos, air compressor, water pump and other minor peripherals. I have two mains rings in my workshop, so I may use the second ring for the compressor, which I haven't bought yet, but it will be the largest - silent type- I can safely get away with.
