HI everyone
I have a picture of a old MEM fuse box,which i need to know the size of, it is a job I am pricing for and dont know what size consumer unit i can fit in the small space vailable. The job is a long way from me and i dont want to waste half a day just to measure a space

Well, my electric meter looks the same as that, and it's about 130mm across. If we take this as a reference point, I'd say the bottom unit is about the same, maybe very slightly larger, and the top one has a ratio of about 10:14, so I reckon it's about 185mm across.
