The factory-installed standard lugs (PDG3X3TA400) are dual-rated for aluminum and copper wire. Each terminal accepts two conductors ranging from 3/0 AWG to 250 kcmil.
How is ground fault protection handled on the PDG33M0400E3MJ?
Ground fault protection is integrated directly into the PXR 20 electronic trip unit. The G in the LSIG trip function code indicates that ground fault sensing and tripping are built-in, eliminating the need for external ground fault relays.
