c. The existing switchgear is arranged in two sections connected by a tie breaker and critical equipment has two feeds, one from each side of the switchgear.

The design of the switchgear should allow for temporary partial installation and safe operation of such an installation in order to minimize the amount of time the switchgear is out of service during the installation phase.
