what chart is that..
where did you find it..
and by single core.. do they mean a SOLID copper wire, using in a "grounding wire" situation
6ga is not rated for 95amps in commercial or residential use,
and while a solid wire might carry that amount in open air strung between power poles or for a safety ground,
it will never safely carry that amount enclosed with out getting hot, being a safety hazard and causing severe voltage drop..for 12v inverter input
go ahead and try it.. make sure fire insurance is paid up.. be prepared for the claim to be denied
and no i am not being facetious
standard breaker/fuse sizes for enclosed wiring
14ga 15amp
12ga 20amp
10ga 30amp
8ga 40amp
6ga 50amp
4ga can't remember
2ga 100amp service entrance
my OEM Freedom-10 1000w inverter/50amp charger was wired with "one aught" aka 0ga
NO you cannot use 6ga to safely power 100amps into a 2000w inverter
