I’ve always found gauge to be especially odd, because the number gets smaller as you go bigger, so at one point you can’t go any further even though you can go fatter.
lol “gauge”
americans will use anything except the metric system

Yup, I work with 4/0 (0000) cable pretty regularly, for things like generators or powering large systems. We have a few trunks full of cable, and it takes a crew of 2 or 3 to actually lay it because it’s so heavy. Usually one person pushing the trunk along, one focuses on uncoiling it from the trunk, and one focuses on actually laying the cable. We use five conductors at a time (one neutral, three 120v hots leads, and a ground,) so it’s a big bundle. Each cable weighs a little over a pound per foot, and there are five bundled together. So a 150’ coil can easily weigh 750-800 pounds.

Oh ffs I should’ve known.

What is the metric unit for cables?
lime@feddit.nu 2 months ago
for cross-sectional area? mm^2^.

16 AWG – 1.3 mm^2
14 AWG – 2 mm^2 12 AWG – 3.3 mm^2 10 AWG – 5 mm^2
For us from the civilised part of the world ;-)
However, as in Europe we have 230 V system, approximately half the cross section, stated in the table above, is sufficient.

Both are measurements of cross-sectional AREA and are defined in terms of square millimeters (mm^2), not mm.

That’s exactly what I wrote
mm^2
should be rendered to square millimetres (mm^2) by the browser / appWolf314159@startrek.website 2 months ago
Sorry, that’s not what I see.
