I am a hvac tech, but my question is I have 2awg stranded and my plug is 6awg, will it matter much if I cut some strands to fit my plug? the plug is 60amp 250vac for a piece of kitchen equipment if the matters.
AWG 2 reduced by 50% or increased in resistance by 200% becomes AWG 5 so AWG 6 plugs can tolerate a reduction in strands of 50% easily.
The power dissipated per foot of AWG 6 @ 0.32 mOhm/ft at 60 A = 1.2W/ft for internal wires which would barely make the wire warm and the AWG2 even less W/ft.
The connector screw contact resistance will be greater than the few mm reduction length/diameter in strands or 5.4 uohms/inch increase in resistance/pair, so I do not see any issues here.
Use a crimp lug or ferrule for termination.
