with so many of the houses in this region built in the 20s, 30s, etc., and without an electrical system designed for properly grounded three prong outlets, I am wondering how many have gone the route of having a properly grounded, ground wire fished throughout the home into each outlet, in order to ground each outlet to code. If anyone has had this done, I would also love to get a sense of how much it cost? It sounds like it would be costly, time conmsuming, and require breaking into wall cavities. Thanks in advance... |

I believe that in the older homes,B.X.cable[metal sheathed]was used along with metal boxes.This would serve to ground the system.Maybe someone who knows more can elaborate. |

Houses built in that period used armored cable. The armor and metal juction boxes can serve as a ground so long they are properly secured and form a continuos path to the service panel.
If this is the case, it is a very simple job: just wire the ground terminal on the receptacle or switch to the metal box with a grounding screw. There should be a threaded hole in the box to accept the screw.
Additionally, GFCI receptacles do not require a ground and will still provide ground fault protection. |
