continuity question
I turned off a circuit to change an outlet. When I tested with my multimeter with the power OFF. I was getting the continuity alarm between all the wiring.... hot and neutral, hot and ground (the metal box and conduit), neutral and ground. Everything was showing continuity.
Please explain why that is? Or is this indication of a problem?
BTW: I have all metal conduit, no ground wires if that helps.
Thank you.

I think I understand but I am not certain.
For example, at the point I tested the continuity (with the power off) there was a lamp downstream that was switched on (no power of course) so I am getting continuity thru a light bulb?
And say I tested the wiring downstream of that light fixture that was on...it should have no effect on the reading at that point?
I should also note, everything works as it should... I assume if there was actually a hot touching ground a breaker would have tripped.... not the case.

yes
right
its always good when the breaker holds. it sounds like you have replaced an outlet.
now you can replace another one. do them one at a time then try the breaker for a test.

PANEL > LIGHT BULB 1 > BOX 1> LIGHT BULB 2 > BOX 2
So testing neutral to hot continuity at BOX 1 with LIGHT BULB 2 on, would show continuity.
Where testing neutral to hot continuity at BOX 2 with LIGHT BULB 1 (or 2) on, would NOT show continuity.
Is that correct?

So it doesn't matter in what position as I describe?
What about if an outlet is pigtailed or fed thru?
