Micc or FP200 cable in chapels or churches ?

Usually price is the deciding facter, MICC is very expensive to both buy and fit. A Company I worked for was rewiring the outside/garden lights for Shakespeares birthplace. We started with MICC, but it was taking so long to install that it was eventually changed to copper/gold coloured FP200, which was fitted in less than half the time, and looked as good. Probably nowhere near as durable or long lasting, but half the price.

The traditional bare MICC didn't always do that well in old churches - the often damp and sometimes alkaline conditions (e.g. where in contact with lime mortar) doesn't seem to do the bare copper sheath much good at all - never mind the unreliability of some the seals over time.

agree - there was plenty of green grot and lower than expected IR results and some quite scratchy earthing. When very wet the sheath sometimes splits, much like a failing kettle element.  I'd not expect FP to be immortal in that situation either though !

However when well installed in a reasonably dry location, pyro is more or less indestructible.

It was the cotton covered rubber flex to the old lamp-holders that usually let the side down first...
