Is it permissible to use a 3 phase RTI (ready to install)I-Line panel for a 120/240v, 3ph-4w high-leg delta system?

Panel application

Product Line:


B phase High-leg

A standard 3 phase I-Line panel can be used but the user must abide by the notations provided in the Information Manual that is supplied with the panel. These notations state that ``When wired for Delta Systems, phases A and C must be 120V to neutral, Phase B 208V to neutral. Connect only circuit breakers rated 240V AC minimum, NOT 120V or 120/240V, to phase B``. No 1p breakers can be put on the B phase .
