The amount of current a wire can "handle" is based on its
temperature rise and that, in turn varies with its cross-sectional
area. So, a wire which heats up to, say, 40°C over ambient with 5
amperes flowing through it would heat up to something like 120°C
with 15A flowing through it. (Less actually, but since you like
vague, there ya go.)

I see. Since a puny 80 amp service is good enough for you, it should
be good enough for everyone else?

And you're not egostical?

You're a fucking joke is what you are.

No, and it doesn't matter. What does matter is that I _have_ the
capacity should I need it.
