I have searched the online info, including manuals but have not found a definitive answer for this question so hoping someone (Zog?) may be able to answer this. The above trip unit is on a ITE K-600 breaker and the unit Ampere Tap is set to 400A. My question is are the CT's tapped to match the SS-5 trip unit tap setting? Or can the tap be lowered to 250A by just moving the tap plug and there is no associated tap of the CT?
