If (after shutting the breaker off) I disconnect a switch or outlet or fixture from the feed wire and then turn the power back on (assume I've capped them for safety ) is the white wire (neutral) carrying any power?
If it is a light box or switch box where the whites were tied together then the neutral was spliced to carry the load through the device. A switch with say two black wires and one on each screw of that switch and then two whites tied together is carrying the neutral to the load of what the switch is working. If you have a light box where several white wires are tied together then they are spliced to carry the neutral load through them. If you disconnect the main neutral wire then no, No load is going through them, but down the line you may have things that will not work because of the neutral being disconnected. Neutral wires a conductors they are grounded conductors and can shock you the same as hot wire, so you should use caution and always treat them as a hot wire. Happy new year
Not unless someone before you screwed up. When ever you work with house wiring always assume someone erred and the stuff hot all the time. Even after I check a circuit with a meter I still have enough respect to treat as hot.
That neutral carrys the 'return' from the whole circuit. You might 'see' a small potential to ground on a heavily loaded circuit, (the differential between the resistance of your ground and the resistance of the neutral under its load), but it shouldn't be much. Just on general principles though, if you disconnect anything, disconnect it completely. BTW.: If you're talking about a switch, there may be a white wire connected to it, but it is NOT a neutral.
NO.not normally.also check the white wire to see if it is the neutral.then you should be o.k.is this what you intend to do.or are you just asking.
you should get a hot wire circut tester to be safe.it is just a stick that lights up when there is power in the line you are touching with tester. I`ve seen power in ground lines, so be carefull
