Reponse to Questions

1. On sheet E0.3, a temporary feeder from the existing 750kVA transformer is shown to be two sets of #500 copper. There is only one existing conduit set for use for this. What is the plan for the second conduit or is it up to the contractor?

Between the secondary of the transformer and the temporary main circuit breaker, the intent is to pull all the conductors in the one spare conduit. If the contractor feels that he may not be able to accomplish this, the contractor shall run an additional appropriately sized conduit by his means and methods and make repairs to any penetrations. The neutral may be downsized to 350 kcmil.

Between the temporary main circuit breaker and the MDBA, may run one 4-inch conduit or two appropriately sized smaller conduits.

2. Spec section 26 05 19 indicates that independent 3rd party testing may be required for
