33coupe: Thanks for that.
Have you noticed a difference between the 12 and 14?
I am contemplating between buying from 12AWG from BJC and 14awg from trademe etc.
Sorry, unable to do a comparrison - the 12 AWG cable is for the HT/sleepout we're building at the moment; the cable's in the walls but the build's not finished (plastering happening today, so not far off!).
Also, I'd need to compare the different cables on the same system to be meaningful, which isn't a practical option.
I'm sure either of these options will do fine for your needs - either way isn't a huge outlay. Good luck!
