a The highest steady-state voltage across the open contacts that a loadbreak connector is rated to switch is the maximum phase-to-ground rms voltage for phase-to-ground rated devices or the maximum phase-to-phase rms voltage for phase-to-ground/phase-to-phase rated devices. b Based on a sensitivity of 3 pC (see 7.4).c Phase-to-ground. d Phase-to-ground/phase-to-phase.
