I need to know the wire type to find supplier. I need 70 foot of 2/3 with ground (4 conductors) that will run up wall then inside attic then down wall to new sub panel, must met code as must have a protective jacket.

What code are you referring to? CEC? NEC? Local?
Since we don't know your location we'd need to know this.

SER or NM cable would be typical in the US.

Sorry for missing information, Location is Bellingham, WA. I not know local electrical code..

For 100 Amp, I then need 3/1 with ground thank you...
