A lot of French ehus are only 5A and the leads are often only used to power the mains charger. They probably get away with it because they expect little from their ehu connections. In contrast we expect to boil kettles or run electric heating up to 16A.But how many of us have seen the French using theirs coiled without any problems most of them have a reel with at least 70 mtrs on and only use 30 leaving the rest coiled tightly on the reel even sharing with another motorhome
