If you had PVC/plastic electrical boxes behind the outlets it shouldn't conduct the electricity around the outlet like your describing even on a really sensitive digital noncontact voltage pen and those ones typically don't let you attach a ground wire to them because the material is an insulator unlike metal ones which just ground it to the box which could maybe send it through the wall. You might want to look into the cause of the excess voltage for health & safety. | |

If I put two layers of plywood, then it doesn't beep any longer, neither for the wall, nor for the locations around switches and outlets, and the only location where it beeps is around the service panel. | |

Sometimes if the detectors are too sensitive, giving them a "shim" off the wall like that will reduce sensitivity enough to get only the positive hits where there's actually a wire in the wall. | |
