[QUOTE="Apache, post: 16867, member: 828"] Now I can't quote regs but I suppose it depends what the customer wants. If you fitted a stand alone RCD before the existing fusebox and swapped the wired fuses for MCB trips it would improve things. You could also re-sheath the green cables green and yellow if you saw fit. The wiring is modern PVC and may well be ok. I don't think there's anything wrong with the cable sizes and this arrangement would suit many smaller houses. If customer wanted further circuits added then a new CU might be better idea. 46amps isn't a big load. No electric cooker or shower so ok. Do we have an immersion heater to think about? Although this CU doesn't comply with the 17th [B]IF[/B] you are not altering any circuits then I think the modifications I suggest above would improve the safety without requiring a complete CU change? I must stress I'm an amature (with a signature now :D ) [/QUOTE]
