The expected transient level for CAT IV is 6000 V, CAT III 4000 V, CAT II 2500 V and for CAT I 1500 V. For CAT I the transient levels can be specified differently and they are then designed and tested accordingly to assure that they withstand the expected transients.www.megger.com 4342 A guide to low resistance testing www.megger.com
