Hello all
It's OK, I understand the Part P stuff and the insurance invalidation stuff and the *risk of death* stuff and I am not proposing that I do this job myself.
I am simply interested in learning and understanding coz I find it interesting.
I've done a fair amount of reading in forums and stuff about how the job of replacing a CU is done and I want to know if, they way i would do it, is actually the way the spark will do it when I call him in. I just wana understand what he is proposing when he tells me what he is going to do, plus I kinda want to *be right* by working out the correct way of doing it.
So...
We have an old fuse wire type CU.
It has 3 fuses: 5a Lighting, 30a Downstairs ring and 30a Upstairs ring.
There is no oven wiring as its all gas and there is no electric shower (it runs off the boiler with a pump)
If I was doing the job I think I would put a new insulated consumer unit in (prob a small 5 way one)
I would have a 6a MCB for the lighting, a 32a RCBO for the downstairs ring and a 32a MCB for the upstairs ring.
I guess they would either pull the company fuse and get them to reseal or have them fit a switch first.
I don't think the house is big enough to warrant a split board due to the small number of circuits.
I don't really understand how to know what type of earthing it has (TT......). The lighting circuit is earthed and there are earth wires on the gas meter and the boiler pipes. And I dont understand what differences this makes to the replacement of the consumer unit.
Am I on the right thinking lines or will it be done differently?
Thoughts, comments, more insight.... thanks all.
