I would not know BX from BS so let me describe it differently...it looks
like 2 wire romex but its kind of a fabric covering, NOT on the wires
themselves that is normal vinyl just the sleeve that holds them
together. Its only 2 wires at the breaker box also, no ground anywhere. I
have also put in some 3 prongs with only 2 wires a few times but that is
not legal and not safe either since you assume you have a valid ground when
you see 3 prong plugs.
Since this is a bathroom and I had the drywall off I thought I would try
and get it right. The GFCI actually had instructions for 2 wire wiring so
from that I assumed it was ok and I checked with the codes and it is
legal. I ran new romex with ground and connected the ground on the 2 plugs
but the ground is not connected to anything in the attic, it will be later
this year (summer sometime) when we put in a new main panel but this way I
don't have to pull the drywall back off the bathroom. It was designed to be
a temporary fix but the GFCI solved all the problems for me.
