[QUOTE="Phoenix, post: 552831, member: 8133"] What rating is the MCB? If 32A then the situation as you describe would be wrong Those cables are probably circa mid 60s. Imperial sized cables were used upto somewhere around 70/71 but at somepoint they stopped tinning it, which was a hangover from rubber insulation and they realised no longer necessary with PVC. Conversly its not much before 1960 otherwise they actually would be rubber. [/QUOTE]
