| I was replacing an outlet today and double checked the circuit after turning off the breaker. To my surprise, it showed about 6-7 volts. I traced the wire back to a junction box and checked it from there with the same results. The wire feeding the junction box is a 12/3 and it appears 2 circuits share a neutral. What could be going on here and should i be concerned? |

| Bet you are using a distal meter. The input impedance of digital meters is so high they can read voltage that is capacitively coupled to a conductor in proximity to a hot conductor. Plug a light into the receptacle and turn it on. The filament will provide a path for the coupled voltage to ground and you will now measure 9 volts. The effective source impedance for the coupled voltage is very high, but the multi mega-ohm input of a digital meter can read it. |

| Distal meters? I always use proximal meters. |

| Thanks for the response brickeyee. Learning something new every day. |
