Electrical Wire Identification

[rdhetrick]

Hi all,

Trying to help my dad identify some wiring in his coach for a project. Manufacturer hasn't been any help so I thought I'd try here.

He has two wires that we are trying to identify the wire size. Seems the obvious method would be to use a set of calipers, but he doesn't have any.

Anyway, there are two stranded copper wires, each with different markings. Anyone recognize the markings or format?

Wire 1: "150 FA Ground"
Wire 2: "603c GLY LPS"

I've not been able to find anything.

Thanks in advance!

For wire 1, google says "For 150 amps in THWN wire size is 1/0"

I cannot find wire 2. Perhaps compare it to wire 1, assuming it actually is 1/0. You can consult a wire table for that.

I would think all you'd need is a simple ruler to measure the diameter.
