Discuss A/C installation "outdoor to indoor" cable query in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

I did my F-gas but steer clear of A/C work tbh. Best to stick to your own trade.

So out of interest what type of cable do people recommend for this interconnection? Would need to be a multicore flex suitable for outdoor use.
 
So what is the best type of able to use for the interconnection?

I keep seeing AC engineers using SY outside and I'd like to offer them a better alternative.
 
We shouldn't be putting any departures down really. No more SY cables for AC interconnection then?
 
I generally use YY for interconnections, SY is way to hard when you get to the indoor unit, also it looks a mess. Outside the YY generally follows the pipework so i hide it within the overall clump and tape it all up with pipe insulation tape, thereby no UV, mech damage is negligable.
BTW the fixed testing to BS7671 is to the outdoor unit isolator, everything else is MIs.
For multis, i use a outdoor grade Cat5 or 6 between outdoor and indoors as its got a much better sheath.
