For electrical equipment, all connections to power are usually grounded at some point. The device may be optionally DC powered, but a conversion from AC to DC still occurs and a path back to earth ground usually exists. snorkel tours out of lahainaWebbGround Potential Rise or Earth Potential Rise (as defined by IEEE Standard 80-2000) is the maximum electrical potential that a (substation) grounding grid may attain relative to a distant grounding point assumed to be at potential of remote earth.
