"BX" Armored cable shield as Equipment Ground Conductor for recept. replacement ?
Hi all,
i recently purchased a home and an inspector indicated that there are several receptacle in violation of the NEC, because the 3 prong receptacles with ground have an open ground. After looking, they are right, there is no receptacle equip. ground connected. The problem is that there is no "green" equipment ground conductor and the cable is the old old (1950 era) BX and I assume it does not have a bonded strip like the new AC cables. It is fasted to metal outlet boxes and is fastened to the service panel which is bonded to the grounding system of the house.
After digging through the NEC it appears that I could use this BX shield as a EGC but wanted to see if I am missing something.
NEC 250.118 Lists the AC as and EGC
AC requirements then refer back to like 250.4 that states the grounding conductor has to be of low enough impedance to allow the enough fault current to trip the breaker at the panel. How can I verify or how do inspectors verify this code requirement is met?
If nothing else, I will replace the outlets with tamper resistant GFCI outlets, to satisfy receptacle replacement without proper ground.
