Can you
tell what size the wire is?
Sorry, I'm not good at telling those larger sizes apart. I looked on
the insulation to see if it said, and all it gave was some
manufacturer data, and a 600V rating.
Well, the 600V rating does tell you that it has a really heavy
insulation.
Not really. It just means that it?s wire for standard US mains wiring
applications; 600 volts is the lowest voltage rating you?ll find for
wire approved for that purpose, and with modern materials that can be
quite thin. Odd that it doesn?t show the size, though; the required
information is maker, wire type (like ?XHHN? or ?MTW?) and wire gauge.
You can of course grab a handy caliper or micrometer and measure it...
In this application it does, since we know what the wire looks like from
the photos. It doesn't have an outer nylon covering as you'd see with
THHN/THWN (which if stranded might also be multi-rated as MTW). The wire
in the photo just has a PVC jacket, so if marked 600V, is going to be
pretty thick. I suspect the sample is just too short to show the complete
specs that were printed on the wire.
