Is a neutral CT needed on a system with just 3 wire downstream loads?

Issue:
Does a Micrologic circuit breaker with an LSIG trip unit require a neutral CT if it feeds just 3-wire downstream loads (no neutral)?

Product Line:
Molded Case Breakers:  

Environment:
Powerpact H, J, L P, R and Masterpact NW and NT with Micrologic trip units

Cause:
Installing and Wiring

Resolution:
No, in this case the neutral would have no place to install and no function. For Masterpact and Powerpact breakers, you would just need to connect a jumper between T1 and T2 on the trip unit.
