What are the rules in the Product Selector for Placing the Control Power Transformers in the lineup? Lineside vs. Loadside?

The rules for placement are:
(a) If it is an essential load, then the control power transformer must be placed on the lineside of the switch. Feeder lineups always have the control power transformers on the lineside (main bus).
(b) If it is a nonessential load (heaters, etc.), then the control power transformer must be placed on the loadside of the switch. Mains and Duplex Mains can have the CPT on the loadside, if there is no control power transfer required.
