Ok I have 6 guage going to a dist. block. Will be feeding 2 amps - 150 watts rms each. That means each load has a max draw of 12.5 amps.
in theory, would 14g be enough because it can handle an ampacity for 15amps (and 12.5 amps is approx 80% of load capacity for 14g).
I will prob use 10 or 12 to each amp, but wanted to hear anyone elses opinion.

Yes, 14 AWG would be fine. 16 AWG would be fine too. 14 AWG copper wire will handle up to 25 amps, by the way.

Really? In the code book it rates 14 g at 15 amps max (which is solid core). Is it 25 amps with a high strand count?

National Electrical Code copper wire ampacity. It has nothing to do with strand count. Insulation type will increase ampacity (for example, Teflon insulated wire increases ampacity significantly, which is why that's what I always use even if it is more expensive.)

Wow! I was unaware that the insulation could raise the ampacity by such a large margin. I was refering to R90 & RW90 in the code book which is used for residential wiring which rates 14g at 20a.
thnx
