How to Convert a 2 Prong Outlet to a Grounded 3 prong Outlet (TYPE AC Cable WITH Grounding Strip). ***IMPORTANT NOTE***: Ensure first that you have armored cable WITH A metal strip inside the armored cable (this was done to improve its grounding capability). This type of cabling is called Type AC, and it looks like the second cable in this picture:
Per NEC 250.118:
"Flexible metallic tubing where the tubing is
terminated in fittings listed for grounding and
meeting the following conditions:
a. The circuit conductors contained in the
tubing are protected by overcurrent
devices rated at 20 amperes or less.
b. The combined length of flexible metal
conduit and flexible metallic tubing and
liquidtight flexible metal conduit in the
same ground return path does not exceed
1.8 m (6 ft).
(9) Armor of Type AC cable with an additional
equipment grounding conductor and as
provided in 320.108."
If not, you're probably going to have to either route new Romex, or install GFCIs everywhere with a label that says "no equipment ground".
