Barely makes the grade as "power" but here it is.
What are your thoughts on the following?
I live in a 1947 house. All the original wiring is flex steel armor. You know, the stuff that when shorted limits the current to 14A while turning a dull red in the walls.
As I have made improvements I replace the stuff with romex with grounds etc. etc.
As a temporary measure I have pulled some of the ancient ungrounded receptacles and replaced them with GFIs (three terminal). My thought is that if a three pronged load is plugged into one of these GFIs, a fault in the load that would normally be expected to trip out the circuit's breaker thru excess ground current will instead trip out the GFI, when the current reaches the paltry GFI trip level, thereby protecting the armor.
Am I overlooking something? While this is not the same as a nicely installed new circuit is it not an improvement over the two wire or three wire with a ground wire hooked to the box?
