BUT BEWARE:
all experimental here ...
if you do not know why this bar is designed as it is, then let the fingers of manipulation!
Reason:
the contour plug (and the bar in this stronger running cable) is so used, so that it will only fit into an earthed socket, and not eg in a Euro extension / -Outlet.
Euro plug / cans / renewals are designed for 2.5A. but this bar has four euro-cans. So are 4 times up to 2.5A possible. So these are up to 10A (in the event the relevant consumers are connected).
an earthed socket is typically designed for 16A. by the contour plug should be ensured that this bar will only fit into a grounded outlet.
would be a Euro-connector on the cable (or the existing connector is manipulated or is itself a Euro plug attached) then there is a danger that a Euro extension which possibly is switched not to burden them with up to 10A. because it is only designed for 2.5 A, then there is a fire hazard.
