Good cable to use outside

[Deleted member 9648]

Is this reconised by BS7671?

Same as thermoplastic insulated and sheathed as far as regs go

hello guys

I have a lighting install at high level outside a house.
I don’t need additional mechanical protection and would like to use a good UV resistant insulated and sheathed cable.
Don’t want to use conduit as it looks ugly.

I normally used white FP 200 which the manufacturers said supports UV light exposure however I have seen a few installs where after 6 years turns to dust.

(I might be getting a phone in from client is a few years time as a result)

Don't forget you'll need to secure it with fire resistant fixings at intervals

Not funny at all, a fact, seen several recent installs on external walls which don't comply for that reason

Are our regs applied retrospectively?

I said recent, ie 18th edition.

Black FP200

I tend to use H07RN-F. It's tougher & thicker than the normal black rubber cable H05. It's rarely on the shelf, normally have to mail order it.

I use black rubber flex. I would usually use H07RN but on occasion would use H05RR. I personally think that even black PVC flex (H05VV) would be ok outside as I put some in my own property many years ago and it is fine. However I use rubber for customers as that is the correct choice. Also, this is only if it does not need mechanical protection, otherwise SWA.

Manufacturers instructions often say to use 1mm H05RN but finding that is like gold dust, so you have to bump it up to the H07RN. You do find that because it is rated up to 700V it is quite thick which can be a bit of a pain sometimes.

This is just one of many useful threads on outdoor cable..

MICC is a superb outdoor cable.
