Is it possible to put one RCD in the electrical panel in the bath?
Hello! Tell me please. I made a XL Pipe warm floor in the bathhouse (in the steam room), with a maximum consumption of 1.1 kW. The question arose about the safety of wiring and installation of machines and RCDs. I consulted with many electricians, read a lot of information about RCD, how and with what to put. But he never received a convincing answer. I am particularly interested in: what kind of ouzo should I put, if I have to put a separate automatic machine 10A on the warm floor, there is also one automatic machine 10 - 16A in the light and socket. The total load on the entire bath will be 2 - 3 kW. Can I put one ouzo on 16A 10mA on two machines. Thank!
Hello! And what is the nominal value of a higher-order machine (the one to which these two machines will be connected to the floor and a socket with lighting)? If 16A - then you can narrowly put on 16-25A at 30 mA. The fact is that if you set 10mA, it can falsely trigger. If the superior machine is more than 16A, then the RCD rating must be equal to or greater than it by one step. Otherwise, at full load, the RCD will fail. By the way, I hope you understand that the RCD in your case will be BEFORE the machines.

1. It is advisable to use a second UZO separately for lighting. Since when you turn off a breakdown on a heated floor, the lighting on your 1 UZO will also turn off.
2. Baths - Especially dangerous rooms and by standards - it is necessary to set 10 mA, the problem is in the equipment that will be protected - often (for example, washing machines) leakage currents are more than 10 mA. If done qualitatively - 10 mA.
If with rectifiers (electronics) - class A. And the price of such a branded RCD is close to 50 Euro.
