There is no ceiling access where our CU is, its a bungalow so can't be accessed from above, need to install new cable for shower (and possibly a submain at a later date, (shower cable first, run submain cable along side it later)), a feasable way of doing this would be 10mm² SWA starting from the opposite side of the wall from the cu, down under the window, along and up and through the soffit into where there is loft access, and from there its straight forward.
So I've got 10mm² on the opposite side of the wall from the cu, how do I connect? I thought gland it with a CW type gland into an adapatble box, end the outer sheath and metal amour there, pass the cores, and the jacket that surrounds the cores though the wall (so its still D.I.) , along with an earth to the armour, and into the cu through the back of it
talking of the cu, that could probably do with replaceing, its a hagar split load unit, but its getting a bit long in the tooth and haveing all outlets etc on one rcd is frankly annoying, rcbos would be better, luckily there is an isolator in the tails. The tails however can't be replaced, being plastered into the wall behind the kitchen units, the problem comes from the fact that the current CU has the incommer on the right hand side, but the MK sentry CUs, which would probably be what I would use if I replaced it, have the incommer on the left hand side, so the tails would not reach, only way I can see around it is to extend them using Henley blocks in an adaptable box, but this means a box on the wall, anyone get any better ideas, if I swapped the isolator to the other end, then the letters marking polarity would be wrong, so I'm guessing this can't be done, unless isolators designed for the other side are available, anyone got any ideas?
My test equipment is currently limited to a multimeter, but I'm hopeing to start on an electrical installation apprenticeship next year, and when I've got my route into the industry secured, I'm quite happy to start collecting test equipment, at the bare minimum I'd like to have a IR/low ohms tester before doing this work, don't think earth loop tester would be absolutly neccessary, could use the max stated Ze for TNC-S (which is what the supply is) along with resistance readings, would be best to have a RCD tester though, even though the RCDs will be new
What would be the implications of ignoring part poo for this?, I'm sure I'd be making it safer as current shower is 8.5kw on 6mm cable bundled in a tight space... finally reading what I have written, please tell me honesty whether you would consider me upto this job, I think I'm able to do it, but I also realise thats its possible to not know just how much you don't know if that makes sense?
Thanks for taking the time to read this long post, I won't be able to reply until tommorow, I'm planning on going out with the intention of consuming alcohol tonight
