Cor, perhaps you meant the *external* wire? In any case, I agree. The standards I'm familiar with (mainly UL and CSA) never specify the material that must be used; they only specify the properties that the material must have. I.e. wire must have a temperature rise of less than X deg.C at rated current (regardless of what material it's made of). So, I can't see any problems in principle with using a stranded steel cable for an EVSE, as long as the steel has enough cross sectional area to carry the current with an acceptable temperature rise and voltage drop. Be sure to prominently LABEL it "steel wire" in case the thieves can read. -- Excellence does not require perfection. -- Henry James -- Lee A.
