Why are extra sections added to an HVL/cc lineup by the product selector?<br />

An extra section in the HVL/cc lineup with an HVL/cc switch in ot will be added when the lineup needs some 120VAC control power and the selector defaults to ``System Calculated``. This means that the control power required be calculated by the selector and the power source will be supplied within the switchgear lineup. This control power transformer requires a separate section and can have an HVL/cc switch as a means of disconnecting and grounding the transformer.

If the power requirement can be handled by voltage trannsformers, they can be selected with and without the HVL/cc switch as a disconnect.
