Is the layout of the distribution panel for the garage properly designed?
Hello. Help with the collection of distribution board, you need a garage of 18 m2.
I sketched my scheme, I'm not sure what is right (by current rating, etc.). Help me choose a load switch at the input, RCD, circuit breakers.
The layout of the switchboard in the garage

And what power is allocated to your garage? Usually set the introductory at 25 A.
3 kilowatts
Then at the input, set the machine to 25A, UZO to 32A, welding to 25A, sockets 16A, light 10A.
Thank you so much!
If the input two-pole machine is set to 32 A, then the RCD should not exceed its parameters: that is, the RCD is set to an order lower than the nominal: it can be either 25 A or 16 A. But after the RCD, also to the machines that go to the consumer objects of the lamp and sockets are also set even lower. eventually. To the consumer of the outlet it is 16 A light 10 A socket group always the current on the machines is higher than the light rating
The RCD is simply obliged to exceed (or equal to) the parameters of the input, otherwise, when overloaded through an ouzo, a current will flow above its nominal value (below the nominal value of the input) and this is bad for an uzo!
Of course, the RCD is an order of magnitude higher than the machine! Otherwise, it is fatal for an RCD. And yet, I would not put a general ouzo at the entrance. Light and welder can not be powered through ouzo. But the question of grounding? If not, then it is imperative to ground yourself! Introductory enough for 25 A. Light 10A., Outlet group 16A.
