QMB branch switches
Environment:
Replacement switch
Cause:
Application and or maintenance
Resolution:
This will depend on the the existing QMB panelboard interior. The replacement switch would be a QMB323TD providing the interior is Type QM(31-inch wide) manufactured after 1961 but before October 1984 OR if the interior is type QW (38-inch wide) manufactured before 1984. If the existing interior is the QW type, with flat bus bar, the QMB310LEX plug-on extension assembly may also be required. Use the outside poles.
