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

How can we help you today?

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.
