House wiring – testing for ground wire?
by Jeff on Oct.19, 2008, under Electrical
I live in an old house in France. The wiring does not follow the norms. What’s more, the existing outlets are all 2-pole (no ground wire).
At some outlets, there are “tied-off” wires of what I suspect to be neutral (leading farther in the circuit) wires. But I also suspect some of these wires may be ground wires. They are not connected to the outlet, but they are connected together – neutral & what I suspect to be ground. Is that possible?
In the walls wiring (at outlet sites), I know how to test for the live wire (phase). But what I want to identify is the “ground”.
How can I test a wire to see if it is a “ground”?
I have a multimeter.
I realize that in the US, ground wires are bare copper. But in France, the ground wires definitely are also isolated wires. The present day norm specifies they must be isolated with green & yellow sheathing.
