[QUOTE="NozSpark, post: 69008, member: 601"] Very good, here are some minor corrections & some additions [B]AC[/B] - NICEIC approved contractor [B]CPC[/B] - circuit protective conductor [B]DI[/B] - Domestic installer [B]IEE[/B] - Institute of electrical engineers (now the IET) [B]Part P - Building regulations[/B] which apply to all domestic electrical installations, all work comes under these regs, but only some types of work are notifyable [B]Part P - Qualification[/B].... there isn't one really, although some training providers are doing this type of course which is described as an entry level qualification for scheme membership.... you still need to have an annual assessment by a scheme provider [B]Ze[/B] - the resistance of the line/earth from the consumers connection back to the generator/local transformer (inc the transformer windings) [B]R1[/B] - the resistance of a circuits line conductor [B]R2[/B] - the resistance of a circuits earth conductor [B]Zs[/B] = Ze+(R1+R2) [B]r1[/B] - the resistance of the line conductor in a ring circuit (end to end) [B]r2[/B] - the resistance of the earth conductor in a ring circuit (end to end) [B]rn[/B] - the resistance of the neutral conductor in a ring circuit (end to end) [/QUOTE]
