Hi want to run wiring for eventual interconnected smoke alarms (my building regs say have to go to mains) so I can plasterboard wall. Got 6243Y 1.0mm 3 core + e for this but need a longer length. The 3 core i got (too short) has red, black, etc cores - is this different from the 1.0mm 3 core + e with blue, red, yell cores or can I use that ?
Am running a 3 core cable from where CU will be, to location of 1 st smoke alarm (the original 3 core (black/red/etc cable) and from there along to location of 2 nd smoke alarm ( 3 core blue yell red cable) - is that right?
Sorry if this seems obvious I didn't realise you got 3 core +e in diff colours
Thanks in advance
