Hello, after some advice before i rip out all of my hard work, and all of my hair!
- background first -
i have been tinkering with electrics sinse i was a kid, learning as i went, and am now what i would call a professional DIYer. i have taught myself how do install electrics, do central heating installations, plaster, lay brick, the lot, and there isnt much i cant do, or learn quickly. (the latest being fibre optic networking). So, NO i am not trained in electrics, but yes, i know what i am doing (in the practical sense).
The problem:
I have installed a new electricity supply to a building (not a public building, not a dwelling etc. etc.). new meter, CU etc. I have 2 rings for sockets, which are floor recessed. the wires run in the floor void.
The problem is that about half of the sockets do not work at all, on both rings. i have checked the sockets themselves, and they are fine. i have tested the V of the wires (multimeter) at the faulty sockets and there is nothing. tracing the problem back it seems that there must be 2 'breaks' in the wire, again, on both rings.
So my only assumption is that there is a physical break in the wire. the wire ( 2.5m t+e) was a little tricky to lay, but did not put any unusual strain on it. the only problem i can see is the possibility of the wire (still fully sheathed) being bent.
Can this type of wire break easily? i have never come across this before. i have done a test to see if i could recreate this break by bending some fresh wire, squeezing with pliers, hitting with hammer etc, but still works fine.
There is no possibility of others breaks, e.g wayward nails/screws, rodents, etc, and the other half of the sockets give no problems and good readings.
am i missing someting fundamental that they teach you on day 1 of electrician school? the break (in 4 places!) seems so unlikely, but i cant think of anything else.. .. ..
Any help very gratefully recieved.
