Will the current style I-line II Busway plug in units fir in the old AP520 busway?
Issue:
Will the AP520 busway accept the I-line II busway plug in units?

Product Line:
busway

Environment:
Class 5600 I-line II busway

Resolution:
The current I-line II current style plug in units can be used but the ground lug will need to be removed. This is true for 600A plug in units and below.
  • New 800A or larger plug-in units cannot be installed on Series 1 I-Line busway.  These newer 800A and larger plug-in units have catalog numbers beginning "PTQ" and utilize a bolted connection to busway, requiring the removal of the plug-in base on the busway to make the connection.  Series 1 I-Line busway does not have a removable plug-in base, and therefore cannot be fitted with these 800A and higher "PTQ" plug-in units.
