I have a question about bonding.
I went to a house and had to replace a receptacle because it was damaged.
It was a 2 prong type supplied by armoured cable that had no bonding conductor. The box was bonded by the armour on the BX.
I decided to change this old receptacle with a GFCI type because of no bonding conductor in the box and the armour of the BX is not suitable for bonding.
I have been looking in my code book on this matter.
CEC 26-700(7)(a) states that if I was to replace it with a 3 prong I could bond it to the cable sheath if the sheath is already bonded to ground.
I think that the armour on BX is not a sheath but is cable armour, because in the code it is always referred to as armour, so it can’t be used as a bonding method.
• Is my understanding of 26-700(7)(a) your interpretation or do you have another?
Any comments?
