HO7RNF Cable vs US equivalent

H077RNF http://titanex.nexans.com/uk/technical-specifications.php is used a lot a lot in the entertainment industry. The North Americans use a similar cable https://www.farnell.com/datasheets/1562972.pdf (Page 5) but it has a paper separator between the cores. Often seen the US cable come to the UK on tours but was curious to see if it satisfies BS7671?

  • I doubt there could be any objection to the paper per se - a significant proportion of UK installations are fed by cables that use paper as the basic insulation (PILC - paper insulated lead covered cables) - and in this situation (as others have already said) there's no reliance on its insulating properties, so the lack of moistureproof sealing isn't likely to be an issue.  I've worked with IT equipment supplied by very large reputable manufacturers into the UK that's come with US flex on it (that was a bit of a challenge until you worked out the US colour code!)

    Actual specifications for cables did used to exist in the wiring regulations many many moons ago - but they've long since been relocated to specific cable standards. BS 7671 now only concerns itself with the choice of a suitable standard (same for cables as for all other equipment that forms the installation) - as has already been said - 133.1 while preferring a UK, EN or IEC standard, will accept a 'appropriate standard of another country'.
