IMPORTANT!
IEC 60364-5-52 serves as the basis for determining the cross-section and current ca-
pacity of mains cables.
As the way the cables are laid and insulated, the ambient temperature and the current ca-
pacity can vary, the requirements set out in IEC 60364-5-52 are to be observed when
changing mains leads. Also refer to the applicable requirements and standards in your
country.
