ge powermark 'gold' (more like crap) making a buzzing sound!
I was ripping out the old 14/2 with the 18 or 20 awg ground on a 15a circut and replacing it wit 12/2g on a 20a circut. i played the old switcheroo by putting the 15a on a lighting circut where the idiots used 14awg for a loop switch on a 20a circut. while i had the panel cover open, i put my multimeter around some wires to measure the amperage load. i also was hearing a slight buzzing sound comning from the panel. is this normal or should i be concerned? i want to replace the panel, anyway so if there is a problem i can have an excuse and a reason for my dad to buy a qo.
