I'm looking for any public domain, UK approved, tables that cross-reference a cable's CSA, diameter etc. with current carrying capacity. De-rating info for grouping and ambient temperature also welcome. I am already familiar with the BS7671 16th Edition wiring regs, but I'm much more concerned with knowing how to select appropriate cables to satisfy the Low Voltage Directive. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
