As a new Part P person (still green) I am looking at replacing a consumer unit. I have checked the main bonding to the water and gas. The clamps were a little corroded and will be replaced. However I suspect there is a bigger problem that could cause a major problem. Both are 6mm cables rather than the regulation 10mm.
Replacing them would be a rather major job with liftting floor boards and even pulling out section of the kitchen.
Would any of the experienced sparks please provide and advice or guidance.
Thanks in advance.
