Question

Quizplus · Accepted Answer

The correct test voltage for proving electrical separation between a Safety Extra Low Voltage (SELV) circuit and a low voltage circuit is 500v d.c. This is a standard requirement in electrical safety testing to ensure that insulation is adequate to prevent hazardous voltages from being present in SELV circuits.
