Live working. Voltage detectors - Two-pole low-voltage type1 Scope This part of IEC 61243 is applicable to hand held two pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: for a. c. voltages not exceeding 1 000 V at nominal frequencies between 16 2 3 Hz and up to 500 Hz, and or for d. c. voltages not exceeding 1 500 V. NOTE The a. c. voltages defined in this standard refer either to phase to phase voltages or phase to
