Q39: Generator Feeder Reuse vs. Replacement – Clarification of Notes on ED-401

We observed that the generator is rated for 825A and is being paralleled using three 3" conduits, likely containing 250 or 350 MCM conductors. Drawing ED-401 includes Flag

Notes #1 and #3, which appear to conflict regarding whether existing conductors can be reused or must be removed and replaced entirely.

- Can you clarify whether reusing existing generator feeder wiring (pulling it back and refeeding to the new ATS) is acceptable, or if full removal and replacement of the feeder to the ATS is required?

- If full replacement is required, could you please explain the reasoning behind that requirement?

A39: The wire can be reused, but it must pass new wire requirements for testing, or it shall be replaced.

Q40: Are you planning to post the sign in sheet and/or will there be another site visit?

A40: It is a part of this amendment.
