As documented by the Task Group, the method to restrict the 42-circuit
limitation only to ?certain? panelboards results in the category of ?Lighting and
Appliance Branch Circuit Panelboard.? Therefore, if the 42-circuit limitation is
lifted, then the category itself is no longer needed. It is ironic that when a
panelboard is presently categorized as ?power? panelboard, the 42-circuit
limitation is no longer a concern. In fact, most domestic panelboard
manufacturers make a 2nd design of product without the 42-circuit restriction,
and export them for installation in Canada where there is no circuit restriction
for any panelboard application.
