flood light cable

The question is certainly valid, for someone of very limited experience and knowledge, not for someone about to undergo an assessment for a competent persons scheme.

Yes, quite right to.

Be more positive man! a valid question was asked.

what are you saying, the sheath is porous?

That's a tough one to answer, as all plastics will have a certain degree of porosity and so will only be waterproof for certain given values and length of time.
However the sheath of fp200 is more porous than a cable designed with external use in mind added to this is the way the sheath degrades relatively quickly in UV light and tends to get a bit crumbly.

Do you have any other electrical work to show your accessor? not sure this will be accepted on its own. they will want something like a consumer unit change or multiple new circuits added (which will need to be tested prior to them attending) as they will ask you to perform a random set of tests, as well as other things. when is your assessment?

Pretty sure you are right there im sure it has to be classed as notifiable work to be assessed on. Additional circuits or consumer unit changes or work in special locations but I might be wrong.

If it's visible and out of any obvious danger, I'd use H07RN-F (Not to be confused with H05RN-F which most suppliers stock but is less resilient, and personally I wouldn't use).You'll probably have to mail order the H07. It's tough stuff. Very rubbery

Are you sure it's H05RNF? That has the same sheath and physical characteristics as H07RNF, it's only the electrical characteristic which is slightly different.
Most wholesalers will stock HO5RRF which is the softer sheathed cable.

Interesting.
I find H07RN-F to be thicker and heavier and more floppy than the harder sheathed thinner H05xx-x stocked by most wholesalers.

I find this http://www.goldwingcable.com/wp-content/uploads/2015/08/H05RR-F-Technical-data1.pdf which reads "This is unsuitable for permanent outdoor use in industrial buildings for non domestic portable tools and for underground laying" versus http://www.goldwingcable.com/wp-content/uploads/2015/08/HO7RN-F-technical-data-sheet1.pdf
The same site You searched for H05 RN-F - Goldwing Cable - http://www.goldwingcable.com/?s=H05+RN-F classifies H05RN-F and H05RR-F both as "light Duty".

Hi Guys, yes H07 seems the better choice for outdoors use. This link has suggested uses etc. Cheers.

I'd install a light switch near the front door.
Run cables up to ceiling, then drill through the wall between the ceiling and floor.
Cable through the wall into the back of the light fitting.

You can't just say H07 is tougher than H05 because that is just the voltage rating of the insulation, the next two letters denote the material that the insulation am doing the sheath are made from.
RN has rubber insulation and a neoprene sheath whereas RR has rubber insulation and sheath, therefore an H05RNF cable will be tougher mechanically than an H07RRF.

The light duty classification is likely a misinterpretation of the voltage rating than anything else.

Don't forget 6491 singles are also in the H07 class of cable.

Hi Dave. Good points. I have nothing further to say, since you could be right
