I want to add GFCI to a pool light circuit. I traced the circuit to a
Square D XO subpanel. The XO series breaker box is obsolete and the only
breakers I can find are regular used ones (no GFCI breakers for XO). It
would be a huge job to replace the entire subpanel just for this circuit,
because it contains a maze of other old circuits. Is there any GFCI breaker
that will plug into the XO box? Is there a GFCI device that I can connect
to the junction box in the pool equipment room? Maybe a simple one switch
circuit breaker box that can connect through a knockout.. something that
would install without turning it into a huge construction job?

You can simply add a GFI outlet in the pool equipment room somewhere
on that circuit before the pool lighting, or use a blank GFI before
the pool lighting like this:

Both offer the same protection. You could probably mount the box on
the breaker cabinet with a knockout, or somewhere on a wall in the
equipment room.

I think that would work and I may order a Leviton 8590-RBW blank GFCI.
Should I place it after the light switch for the in-ground pool light, or
before the switch? There are 3 other patio rooms sharing this circuit for
their lights.

*That device is switch rated so you could replace your existing switch with
the GFI switch. You will need the neutral line and load in addition to the
hot wires.

Ideally you want to place it downstream from the patio lights so if it
does trip, the patio lights will not go out.
As far as placing it before or after the switch for the pool lights,
it does not matter.
I was brainstorming a bit ( too early in the morning for that) and you
could actually just change out your existing pool light switch to one
of these:
http://www.leviton.com/OA_HTML/ibeCC...&section=11624

That would give you GFI protection as well as give you an outlet. But
you have to remember to wire so that the pool lights would be on the
"LOAD" side of the outlet.

I should add that the GFI combo switch/outlet will only work if you
have 110V coming into the switch box for your pool lights.

If you have only a switch leg ( just 2 wires in the box that are
connected to the switch) then you have to use my first suggestion.

that's even better, I like that idea.

*It has been a while since I installed a GFI combo device. I don't remember
if the switched load is GFI protected or not. It doesn't say at the link.

From what I remember, the switch is just a simple switch, it has 2
tail wires on the combo device. It has nothing to do with the GFI
outlet, so the OP would need to tie the neutral of the pool lights to
the "LOAD"side, then tie the hot of the pool lights to one tail of the
switch, then the other tail would simply go to the "LOAD" hot
terminal. Again, this is only if he has the 110V feed coming into the
box.
If the patio lights come out of the same box, he can tie those to the
"LINE" side.

Use a GFCI receptacle as the first device in the circuit. You may also
be able to find a GFCI that fits in a single gang box that does not
contain a receptacle.

I simply pulled the old non-gfci circuit that ran to my detached garage out
of the panel, then ran a short line to a surface mounted box a few feet from
the panel with a gfci outlet. I then pulled the garage line into that so now
I have a much needed outlet near my panel and the garage and underground
line leading out to it is protected.

Did the same for an old bathroom circuit that was not protected - but in
this case I was able to put the gfci outlet in an other area of the basement
where there was no outlet so now I have one and the bath is protected.
