Can someone tell me if there is a limit on how many times you can break into a ring main to spur to a new socket using junction boxes.
I know you can only spur off a single to a single and a double to a double but unsure when breaking into the cable.
I ask this because my sister has just bought a house and whilst taking the floor up to do other works we found quite a few of them. Old style brown junction boxes which I understand shouldn't be hidden under the floor anyway.
One also had an old rubber cable attached to it which disintegrated in my hand when I touched it exposing the live conductors
There is a sticker on the cu showing it had an eicr done in May this year. Should that have picked any of this up?
Just need to know whether to get the vendors sparks back to explain and put right or whether to get someone else in ourselves
