I chose the simple example because everyone can relate to it.
But do you know how to size wire based on whether it serves a
continuous load or not?
Probably not in every case. I know to use 12ga. in most cases in the
wall rather than 18ga. zip cord. :) (Assuming it's copper: if you
find aluminum, it needs to be bigger. Not that you'd want to put
aluminum wire in any new installation.)
How much wire can you put in a pipe?
Off the top of my head, no I don't know. I do know where to look it
up, though, if the situation ever arises. Mostly I have used
non-metallic cable rather than conduit.
Can you bend pipe so that it is located exactly where it is needed
without sawing it to pieces and using a bunch of couplings;
i.e.....wasting material?
How deep do you bury pipe under a roadway.......a sidewalk.......a
flowerbed?
How do you avoid derating every circuit in a pipe?
How often do you have to support armored cable?
How many circuits can share a neutral?
What is the smallest wire you can use for an equipment ground?
Again, I'd probably use 12ga. Preferably with green insulation. (If
the wire itself is green, it's probably been exposed to moisture.)
How do you overcome harmonics?
If the guy won't quit playing when asked, a .357 Magnum is usually effective.
Why do you have to use 90 degree C rated wire at the 75 degree C
rating?
I don't _know_ (I would simply follow the recommended usage). My
guess would be to minimize sagging when the wire gets hot and the
metal expands, which of course may lead to problems.
There are similar bodies of knowledge for plumbers, carpenters,
boilermakers, elevator techs, pipefitters, millwrights, sheetrockers
yadda yadda yadda
Yep.
Having a hammer doesn't make one a carpenter
Having a multimeter does not make one an electrician, either, but it
at least sometimes lets you figure out if the problem is a broken
wire or short or just that there's another switch somewhere that's
off when it should be on . . .
