hello everyone, I have a little problem. I've got a three phase board, it has the three phase sauna, one phase lighting and sockets connected to it. The problem i am facing right now. This is a comercial unit. So the problem is that the sauna makes the RCD trip every so often. And the board is protected by only1 RCD as a main switch. So when RCD trips the whole lighting and other circuits will be disconnected. This is causing a lot of hassle for the customer. And he's wondering if there is anything to do, add additional RCD or do something else without spending a fortune on this.
