More Breaker Panel Mess
chuck wrote in news:haikf.8489$N45.4470
@newsread1.news.atl.earthlink.net: providing an opportunity for a potential difference between your DC ground system and the grounded case of an AC appliance. An improperly wired boat in the next slip can cause real safety problems aboard you vessel. Show me how. The water is earth ground, no matter how the joker's boat is wired next door. If he's wired wrong, the AC current through the water will trip the AC breaker on the dock. Try it. There is NO WAY for the guy's boat next door to raise the AC potential of the whole ocean up off the AC shore ground potential my fridge is connected to! He'd need a thousand amp breaker to raise it a tiny fraction. The shore power ground is hooked to the earth/seawater. |
