I knew that, but was thinking of standard 120VAC,
15 or 20A branch circuits in the house. (FWIW,
one of my stops while shopping earlier on
Saturday was a Radio Shack, where I got a spool
of 4×24ga. telephone wire and some other parts to
do some repairs and modernization on some of the
jacks in this house. (I already have somewhere
around here an assortment of terminals for such
wire and the crimping tool for installing them,
etc. . . .) The house was built in the spring of
1957 my father bought it and we moved in in
August of 1964 and the phone jacks in the
bedrooms take the standard-in-those--days 4-prong
plug, and one of the two modular jacks designed
to hold a wall phone which is the one that the
line used by the computer is running through, as
the other one has a wall phone (black, with dial)
hanging on it) is cracked so the only way to keep
the cord in it is to tape it in place. I went
from dial-up to DSL earlier this week at a
rough estimate it seems to be about 70× faster
so I decided it was a good time to fix some of
those things as I am going around putting the filters in place, etc.)
but 12AWG is the standard branch circuit
conductor.
That was what I based my answer on.
I've installed conductors as large as 1000MCM, but mostly
such loads are fed parallel.
18AWG is going to be used *inside* equipment for the most part if it
is a load bearing conductor.
E.g., rewiring lamps that aren't
working. BT,DT. So far none of them have burned
up or caused the house to burn down . . .

Then there is the consideration for how many wires you can have in a
junction box.
It is not difficult to look these things up, it is difficult to do it
right without derating the circuits.

The answer is 8AWG actually, but you are probably using a different
definition for "equipment" than an electrician is going to use.<G>
Again, I was thinking of things one would find
around the standard residence (or even around mine)
An electrician would be more likely to say "Having a pair of
sidecutters (Kliens) does not make one an electrician".
Nor does having a pair of dykes. Though wrt your
message to Julia, it can get you a magazine
layout. (So I hear, anyway . . . ) Or, some
people could voice their suspicion and others
name a planet after you :
