Just been to look at a repair for a friend of a friend, flat over a shop with electric tripped out & won't come back on.
Went to the shop 1st to see landlord & found shop half in darkness with staff in a flap as all breakers were OK etc.
Told them I'd be back & went to sort out flat, Tennant had plugged in kettle & RCD tripped then wouldn't re-set or so they said. I unplugged the kettle & re-set the RCD but still no power on, used non contact tester on tails & found no live.
Started following tails & found another RCD on the opposite wall that had tripped, re-set and yes we have power.
Great I thought, then the landlord arrives to say that all shop power is back on.
Cut a story short: On checking above the suspended ceiling at the back of the shop, turns out the back of the shop was converted from a storeroom a few months ago & the "sparky" had added the new lights & sockets onto the flat circuits via a big nest of junction boxes in the ceiling void.
Have told the landlord how dangerous it is & given him the numbers of 2 good contractors, told the Tennant she needs to ask for a refund on her electric too.
Traced the flat supply too: Comes off a separate meter in the shop then via about 10m of tails to first RCD in the flat, from there to a Sentry split load CU on the opposite wall.
Gets interesting in there, tails to main switch then out into RCD all MCB's are then on RCD side. What a lash up.
