a. The Circuit Breaker is OLD and has CTs on the bushings. Since this is a Tariff Metering Point, the CB

mechanism box has seals therefore will make the installation works complicated.

b. The space in the Control room is limited therefore no adequate space for any type of panels.

c. The 2 No. of isolators do not have Auxilliary Switches.
