40-year-old residential light circuit tripping intermittently. Finally got a good insulation resistance reading on the wiring after disconnecting and testing half the houses light wiring. Insulation resistance @ 500 volts DC measuring 15 Meg Ohms (greater than 1 Meg Ohm is a pass) The fun part is putting it all back together. WiseOne Electrical Services - 0418200753
