Hi, you have a 4 pole breaker, 2 x 3 pole breakers, and then 1 pole breakers. From your diagram as the 3 lives come in to the input of the 4 pole breaker as well as the neutral. On the output of that 4 pole breaker, the lives, l1, L2, L3 is feeding the 2x3 pole breakers as well as the 1 pole breakers. My question is. From the output of the 4 pole breaker, are all the lives coming from the output of the 4 pole breaker, meaning are you putting 4 wires into the output of l1, L2 and l3 and then feeding each into the 2x3 pole breakers and the 1 pole breakers?
