Hi, can someone help me please. I have always wired boilers with heat resisting flex (mostly non butyl but heat resistant to 90degree). Recently I wired a boiler and the electrician who was only supposed to put a fused spur instead of my temporary plug and socket decided to rip out my heat resitant cable (five core), replace it with some grey multistranded flex with 7 cores. In the process he messed up controls so my customer is left with a system thats not working. I asked him about the cable and he insists that the cable does not need to be heat resistant other than all cables generally. Now I've been taught differently and am unable to find the particular words in the legislation. Is there anyone knowledgeable enough to enlighten me please I can put this to bed or throw the appropriate book.
