Detached bldg., some time earlier someone installed a ground rod at the sep. bldg #8 green and bonded the first j-box where the aerial wires come in. no bond between neutral and gr at garage, so fault would try to get back to house gec/rod. She was having shocks while running her electric potters wheel during rain season worse but a tingle when dry. so does there have to be a addtl short in equipment for her to recieve a shock I.e. bonded neutral in a electric wheel for the 2.5amps to get back to the return via the case. also the wheel has a 3wire plug so I assume its bonded to the local ground rod. could there be a current loop in garage equipment that I need to find? thanks chris
