| True. But to clarify: three prong GFCI receptacles that aren't grounded
| are legal. Ungrounded three prong outlets _downstream_ of a GFCI are
| also legal (as a retrofit), as long as you use the stickers saying
| "ungrounded outlet" on them.

How about one of those grounded plug adapters ... the kind where you have
3 holes on one end to plug in a grounded plug, and only 2 prongs on the
other end to plug into a legacy 2-hole no-ground outlet ... that integrates
GFCI protection as part of the adapter? I've seen GFCI cord sets, but only
with a grounded plug. How about with an ungrounded plug?


The GFCIs look grounded to my tester. I haven't bothered to open
them up and look if there is a ground wire in there.
What I was trying to say is that all of the "normal" (non-GFCI) 3
prong outlets are just hot and neutral with no ground wire in there.
Landlord did the cheap thing, although I don't know of any easy and
inexpensive way to retrofit a ground in to a lot of outlets (say 20+).

As for my sub-panel and 3 phase panel things, I've just ordered a 500'
spool of #1 aluminum wire. It is _WAY_ less expensive than copper. I
will be certain to read up and make certain that I bond everything
correctly, use anti-corrosion goo and make certain all connections
are torqued down properly. The RPC and all of the machine loads will
be made using some copper THHN that I already have.

I've acquired a Cutler Hammer 3BR1224L125 125 amp 3 phase circuit
breaker load center panel and now I need to find some CH BR3xx plug/
stab-in breakers. 3 pole breakers are pricey new!
Anybody have some Cutler Hammer compatible breakers like these:
BR360
BR350
BR340
BR330
BR320
BR315
BR310

Thanks!
