[QUOTE="Rob_the_rich, post: 456148, member: 8419"] looking at [URL="https://en.wikipedia.org/wiki/Skin_effect"]Wikipedia[/URL] page there is a graph showing skin depth against frequency. Steel at 50Hz has a depth of 2mm, so the 6mm x 1mm strip would not be affected by the skin effect. So bg nexus tech is wrong. Good job too in this instance as the worry is overheating of the steel under earth fault conditions, and anything increasing the overall resistance would increase the heating effect Copper at 50Hz has a skin depth of 9mm so no need to worry too much in a domestic environment.
