How to choose an automatic machine and RCD for a warm floor?
Good afternoon. Electric floor heating SpyHeat Economy SH-450W, how to choose the right machine, RCD, what section of the wire is better to choose ??
Hello! The cross-section of the wire is not less than 1.5 mm² not from the point of view of permissible current, but from the point of view of common sense, mechanical strength, etc. 450 W - is its total power? Here, the current is only 2A, take the machine to 6A - this is enough, it is possible less. An RCD with a rated current of not less than the rated current of the machine can be one step more (for example, the machine is 6A, then the RCD is 6 or 10A), and the differential current is 10-30 mA.
