Main power connections should be made with copper wire; use compression
fitting lugs. Wire sizing should be appropriate for the current being carried.
System ratings are listed in Section 6.1.
M3460 ride-thru units only provide full currents for a limited amount of time.
Therefore, wire heating is not as much a concern as mechanical strength.
