[PLUG-TALK] Electrical circuit branch: identify first outlet

[Rich Shepard]

I've learned that I need a GFCI outlet on only the first outlet in a circuit
branch, not all of them. Now I need to learn how to identify the first
outlet in a branch, initially the branch marked in the service box as
'bedrooms/baths'.

My initial research suggests I pick a room (perhaps the bedroom on the same
side of the house as the service box in the garage) and, after turning off
the circuit breaker for that branch, remove the outlet cover, test the
circuit's not live, then remove the outlet and look at the wires connected
to it.

Two wires alone (black and white) means it's not the first one. Put back
everything, go to next outlet, rinse, repeat. Find the outlet with black and
white wires on both the line and load ends of the case.

Is there a better way of doing this? I have a circuit testing tool odered,
but I don't know that I can use that to indentify a circuit branch's wiring
sequence.
