Assume your house is wired with a 200 ampere service (which is pretty
standard for the average sized home). You have two "hot" legs, a
neutral
and ground. The size of each hot leg is sized to handle 200 amperes.
That's 200 amps each, or a total of 400 amps. Yet, the white
"neutral"
lead is the same size as the hot leads .... rated for 200 amps.

Why?

Very few licensed electricians will give the correct answer.

The two ungrounded conductors are opposite ends of a center tapped
transformer and tend to cancel so the neutral only carries the
unbalanced load, max 200 (if one side was totally unloaded)

How did I do ... for a guy with no union card?



Not bad. The two hots are 180 degrees out of phase, so the neutral only
carries the difference between the two. If both hots are drawing
exactly
50 amps, the current flowing through the neutral is zero.

OK when does the neutral need to be bigger than the ungrounded
conductors?

3 phase Wye service.

You guys are talking way beyond what union wirenut twisting schools teach.

Nope, thank God you and your union slackers were nowhere to be
found... The work got done, and done right.
How would *you* know the job was "done right"?

Pffffttt...

You can "pffffttt" all you like, but it's no substitute for the cold
hard fact that you surely know nothing about wiring a home properly,
or, in fact, much about anything else, either.

House wiring isn't exactly rocket science Harry. * There's a good book
for you on on subject at Barnes and Noble entitled, "Home Wiring for
Dummies".

In fact you can legally do your own house wiring in most jurisdictions.

It's funny. He pretends to be a union hack, pretends to have a degree
from Yale, pretends to have a mechanical engineering degree, pretends
to know anything about everything, but when someone mentions working
on their own stuff, he just can't imagine it! I LIKE doing my own
stuff, that way I know it's done right. But, then again, you have to
have some intelligence to do so.

Wiring is not that difficult, especially if you don't have to bend
tubing. You can find all you need to know in one book. Naturally it
takes longer than one who does it every day. A box of wirenuts has a
table with all the allowable combinations of wires for example.
