I'm trying to determine which circuits are controlled by which circuit
breakers on a sub-division home built in Southern California in 1980. I
want to minimize the process of shutting off one circuit at a time and
then walking around checking lights and wall outlets. I'm hoping some
experienced house construction electricians can make my task easier
using the information provided below.

There are two black toggles, mechanically linked, with the label 125 amps.

There are two black toggles, independent of each other, with the labels
50 amps.

There are two green toggles, independent of each other, with the labels
30 amps.

There is a single black toggle with the label 20 amps.

There are four red toggles, independent of each other, with the labels
20 amps.

There is a single black toggle with the label 15 amps.

There are four blue toggles, independent of each other, with the labels
15 amps.

There are cryptic handwritten letters (perhaps remnants of faded words)
like R, V, Fau, and DG next to some of the circuit breakers.

Ideas?

Ok, let me get this straight.

You're too lazy to hook up a light bulb and throw the switch.

You're gonna trust your safety...you're gonna risk DEATH
by relying on input from someone who has never seen your house???
You're gonna risk DEATH on ANYTHING you get off the internet.

NEVER, EVER, DON'T EVEN THINK ABOUT believing a circuit is OFF
without TESTING IT, EVERY TIME, no matter what is written on the panel
and ESPECIALLY based on some input from the internet.

How stupid are you?

The guy was obviously just asking for advice on narrowing his search.
The size of the breakers is something that the average home owner does
not have to know.

You seem to think the OP was just going to label the panel without
doing any tests. It is smart to ask for advice. He has been given
good solid advice on how to narrow his search.
