I have recently bought an old house well actually its two houses which is part of the problem. The house was originally 2 buildings and until recently one was uses as a shop so had a commercial electric supply while the house has a separate domestic supply. (Incidentally the shop supply is actually 3-phase - previously a saddlery - although 2 phases are header only). The wiring in general is awful, the house supply doesn't even have a distribution board just a collection of circuit switches. I would like to get rid of one supply (I don't like paying 2x standing charge) but don't want to re-wire before doing so. The distribution 'areas' are actually quite close together (~1m separation). My prefered option is to put in a 100A switch/fuse so that I can work on the circuits safely later, followed by a connector block to split the tails to the two sites. Is this OK on a TT installation? and will I have a problem getting the board to re-connect to it given that the earth is not really satisfactory - currently only 4 or 6mm2 earth wire from the electrode to the distribution 'area'? If it is OK where can I get a switch that has terminals large ebough to accept the meter tails. Some of the answers are in previous threads but I'm not sure if the TT installation creates an issue as I'm used to T-N-C-S on my last house.
