[QUOTE="danmoriarty, post: 269558, member: 17741"] 1. Are we talking about the mechanics of the cable or are we talking about the csa of the cable? Also is this cable choice solely for the cable from incomer to the DB or is it a cable choice for all equipment installed in the surgery? Mechanics of the cable: "HTM06 15.20 Multi-core LV distribution cables should have a black outer sheath to denote their voltage rating." And according to figure 39 of HTM06 cables should be double insulated? 2. Not just a single pole stand alone rcd unit? 3. going to say 1mm because table 4d1a show a current carrying capacity of 11A, the 10A RCD will protect the cable from any damage. Unsure as to what to do with the touch voltage so going to stick with this answer for now (although i have an inkling it is to do with 411.5.3?) are tails to be upgraded to 25mm? thats all i have for now......
