Hi, this concerns a trailer home. A new 100A G.E.-panel was installed. The outside trailerhome metallic paneling reads voltage. When a reading is checked on the paneling of the trailer, the voltage reading will differ at times when certain breakers are clicked on and off, the reading is checked at the ground rod. Also there is no ground wire coming from the meter can. I'm thinking that the wiring in the walls could be grounding and causing a short, but also, could the missing ground wire from the meter can cause this? By ordinace the trailer's new panel needs no bonding. Some advice was given that the panel should be bonded but, with the bonding screw tightened in to the panel, there was no difference to the situation. The main concern here is that someone could get terrible injured from this stray voltage. By the way the trailer is not in use as of yet, due to this matter! I would greatly appreciate any advice concerning this situation. SJR.
