1 terminal, Live!, but it’s constructed with a bolt down the centre creating two apertures. Daisy chain 2 sets of 3 (serial) to each side of the bolt. This also gives equal pressure on your solid core cable preferable to having one single core that potentially could come loose.Yep, backing you up on this, advice if I'm to run six Gigawatt MCBs is to daisy chain three each to both terminals.
Just for clarity should anyone be thinking it’s the two terminals, live and neutral, of the Doepke.
