ELECTRICAL ADDENDUM 1

DATE: September 9, 2026

PROJECT NO: 26-0526

PROJECT: Mammoth Creek Fish Hatchery Improvements

DIVISION 26:

DRAWINGS

SHEET ES101 – ELECTRICAL SITE PLAN

1. The transformer and a new phase converter (associated with generator) have been added/relocated to the hatchery building where one of the generators is being removed.

SHEET EL202 – HATCHERY BUILDING ELECTRICAL PLAN

1. The transformer and a new phase converter (associated with generator) have been shown on the floor plans for the hatchery building.

SHEET EP401 – ELECTRICAL ONE-LINE DIAGRAM

1. The emergency one-line has been revised as follows:

a. The generator was changed to a 240V single phase generator instead of 480V.

The size of the breakers in the generator have also been modified.

b. One of the breakers feeds directly to the transfer switch in the filtration building.

c. The “second” breaker feeds a new phase converter (refer to Keynote (X1) on this sheet. The phase converter will convert the 240V single phase to 240V three phase. Then, the intent is to feed that three phase power to a buck boost transformer for 480/240V delta with a high leg which then feeds transfer switch in hatchery building.

( 8 0 1 ) 5 3 0 - 3 1 4 8 r e s o l u t g r o u p . c o m i n f o @ r e s o l u t g r o u p . c o m

d. Prior to ordering any equipment associated with generator (generator, transformer, phase converter, etc.) the contractor will need to verify the existing power and phasing to insure that new generator components are compatible with existing power connections.
