Okay got an interesting one on the go and I think I know the answer but just wanting to see what others would do
Been tasked with wiring up a garden room/office, fair size (probably needs planning but doesn’t have it) electric heating, led lights, possibly electric water heating, ive sized the cable feeding it to take at least 40amp for future proofing
The issue.
Current supply is 100amp single phase feeding the large (5 bed) house. It also feeds a garage block, a plant room, a bungalow where the son lives and another studio flat where another son lives (all on one plot of land). The bungalow then feeds another small ‘annex’ with its own electric water and space heating.
My concern is that this supply is already overloaded. Last year the 6mm cable running down to feed the bungalow burnt out and was repaired, I think largely due to the fact it has little over current protection (looks like someone has removed the existing Wylex 32amp mcb and bodged in a 63amp!
im not really prepared to make the final connection to this setup as it Already has so many issues, I have told the customer I need to make an assessment on the existing load and establish whether there is any capacity. I think from what I’ve already seen the only option would be a supply upgrade, I’m sure diversity won’t even bring me close the supply available, they are already exceeding it, although obviously not enough to blow the cutout fuse
anything else I should consider? Or just run!
