what gauge wire that has 1.25mm diameter PVC jacket

[Erick]

Appears to be two lead, multi-stranded hook up wire with 1.25mm diameter
PVC jacket. Short of stripping and measuring the wire itself, is there
any way to tell what gauge it is with the information provided? Thank
you.

1.25mm is 0.049 inches. That includes the insulation? And presumably, that is only one (1) lead? Nothing is written on the wire itself?

At a S.W.A.G., allowing the PVC to be somewhere at /around 0.30 mm of the total diameter +/-, that would put you at 20 gauge AWG, or so (0.9mm).
Given that the most common wire gauges found in the USA are even numbers, the options are 22, 20, & 18. 18-gauge is too thick unless the PVC is very thin. If thick, then 22 gauge is most likely.

You could get a rough idea of the diameter and stranding by measuring
the dimensions visible across the cut end.

..but the answer is no. Anything but an electrical/physical
measurement or labelled specification is guessing.
