43.3 Maximum-voltage measurements43.3.1 The maximum voltage used as a basis for the calculation of the dielectric voltage-withstand testpotentials specified in 43.1 and 43.2, and the determination of the minimum spacings specified in Section35, Spacings, shall be determined in accordance with 43.3.2 and 43.3.3.43.3.2 A connector or comparable part that is capable of being disconnected during intended operationis to be both connected and disconnected during the test so that the maximum voltage is obtainable.43.3.3 When a complex voltage is present, the peak value of the voltage is to be measured and this valueis to be used for calculation of the dielectric voltage-withstand potential and determination of the minimumspacings. For a sinusoidal or a direct-current voltage, the rms or average value, respectively, is to bemeasured.
