Wire Guage Notation

I have seen wire gauge listed as 2*3 AWG and also as 8-10 AWG.

What do these statements mean when specifying a wire gauge?

Thanks.
 
I understan about wire gauges BUT

8-10 it's probably referring to the 10awg wire made up of eight strains of copper.
 
I think this answers the question on the 2*3

I didn't find anything on the 8-10 AWG

Common notation on terminal lugs indicating range of wire gauge that can fit and be crimped acceptably to a particular lug size.

Sometimes a multi-conductor cable may use a different size gauge wire for ground wire then current carrying pair.

Cheap crimp terminals generally
12-2 12-3 for example is three conductor cable with no indication of stranding and generally is house wiring. 12-3 WG is three insulated conductors with one bare ground.

Wire gage is not a range

the link above is useful: see photo
as shown multiple sizes can be wrapped in a single ‘cable’ for various purposes. Like audio-use cable that contains 9 (or 11?) different conductors, trailer cable that has 7 or 8 conductors and three or for different gages depending on color/function.

18-3 is generally tstat or alarm wire and not probably applicable to solar other than maybe monitoring devices.

Most likely it means 2 lines of 3 gauge (odd) and 8 or 10 gauge is acceptable (probably depends on distance).

Probably need it in context to understand what they want.
