it depends on the CCC and other properties of the"flex" more and more shop fitting ,motor rooms,bouler rooms are being done with YY and SY "flex" but a lot are wrongly installed specialy the glanding and earthing of braids
Then there is the question of colours in 5 core YY all cores are black with numbers on them many PIRs iv seen no other markings put on the cores not even on the earth its Shoddy instaqllers who give a bad name to this stuff the YY,SY are good in many other ways when installed CORRECTLY but its easy to mess up the installation of these
