Actually this is a breaker differential so it does both protection against overload and current lost. By the way the differential is useless if you plug it behind the one you already have in your house Board for all the wet zone (kitchen, bathroom,...)Ancalagon wrote:It's not a breaker (that will switch off if the need of electricity is over the limit) but a "différentiel" which switch off when there is a loss of 30mA on the alimentation.
Thus, the différentiel will work. But I'm not an electrician
And put it near the installation. In the control box is better for me.
Here it seems that it’s plugged right behind the main breaker so before the differential what seems the good way to make it.
