Wiring for20 Amp Double Pole circuit breaker for GE Powermark Gold breaker panel

I need wiring for 20 Amp Double Pole circuit breaker for GE Powermark Gold breaker panel for a residential AC install in Toronto, Canaada. Should I be using 12-2 w/ground Romex (Red colour sheath) or Romex (yellow colour sheath) wiring?

I was told the yellow colour Romex could cause a fire in this particular application.

Can anyone please confirm if I need to use red and what is the difference?

Thanks!

Assuming the air conditioner is 240 volt, you would use Red 12/2 w/G. Yellow will *Not* "cause a fire". The difference between red and yellow romex in Canada is that the red romex has black and red colored internal conductors, whereas the yellow has black and white internal conductors. The red is used for 240 volt applications so that it is clear that neither wire is a neutral (grounded conductor). Yellow should only be used for 120 volt circuits that have a hot and a neutral (grounded conductor).

In the US under the NEC we can use the Yellow jacket #12-2 Romex and re-identify the white as red for 20A 240V use.

I assume this is for a 240 volt load without the white neutral.

In Canada I think you use the red NMD90 HEATEX cable. It has black, red, and bare conductors - no white to re-identify. See notes at bottom: NMD90 - ECS - Electrical Cable Supply
