Hi there all
I have a quick question. My garden supply CU has a 100A AC RCD as main switch - off that is my greenhouse supply circuit. Then a 63A AC RCD which protects 7 circuits, one of which is a pool heater. I am replacing the old heater and the new one requires residual DC protection. Can I replace the 63A RCD with a Type A ? My gut feel is that I will have to replace the 100A RCD main switch to a Type A as well ??
Could another option be to move the pool heater circuit next to the main RCD switch , then it's own supply to a small sub board with a Type A 30mA RCD protecting the circuit mcb ?
