I have used meggering for 1 minute as stated in NETA for field cable installations below 1kV. However Southwire in their website identifies hipot test for LV cables and one of our cleints wants to have all LV cable above 250 kcMil hipotted. Can you explain were is Southwire geeting these values and are they really valid. for example for cables between 550 and 1000 they recommend Hipot at 9.6kV DC for 5 minutes.
