Hello, fellow sparkies. I’m a fully qualified electricianhaving done a 5 week course , got my Part P and everything. Got my NICEICdomestic installer inspection in 2 weeks. Going to rewire my parents house forthe inspector to see. It’s a prefab, all concrete, built about 1950 and iswired in that awful round copper covered cable that fits into the boxes withbrass nuts. It’s all 2 core cable, so there’s no earth. I’m going to do it allin stickyback plastic trunking, should only take me about a week. The niceicwant a small job as well, so I plan to fit a circuit for washing machine andtumble dryer in the only place in my small flat where they will fit. Thebathroom. As the floor is tiled, I can’t get to the socket cables, so I plan tocome from the bathroom light in the attic, down the corner of the bathroom intrunking, under the bath, and fit a double socket under the bath where the tapsare. I’ve looked up in the regulations, and that’s OK because you need ascrewdriver to get the panel off. Also it makes the plumbing easy, straightfrom the tap pipes. And, because there’s no earth on the lighting, I can fix awire from the earth of the socket to the cold water pipe. One thing I could notunderstand from the course is why I need to use thick cable on showers andcookers. Is it something to do with the bigger cable allowing the amps to flowfaster, like bigger water pipes allow faster water flowing?
