About this file
These documents are engineering design drawings for the Dalles Lock and Dam Powerhouse project by the U.S. Army Corps of Engineers Portland District. The drawings provide detailed technical specifications for the powerhouse, including a comprehensive index of reference drawings, electrical wiring diagrams, nomenclature legends, and schematic representations of the facility's layout and equipment. The powerhouse features 24 bays spanning 2,064 feet, with 22 main units (divided into "old end units" MU01-MU14 and "new end units" MU15-MU22), a fish unit, and a station service unit. The drawings include plan views, elevations, and technical details of the hydraulic turbine generators, with specific focus on electrical systems, conduit routing, grounding, and wire identification methods. The project is dated May 2025 and involves detailed technical documentation for the hydroelectric facility's design and infrastructure.

CIRCUIT AND ROUTING IDENTIFICATION
1. ELECTRICAL CIRCUITS AND CONDUITS ARE IDENTIFIED AS FOLLOWS:
A. BETWEEN MAJOR ITEMS OF EQUIPMENT, A THREE PART NUMBER IS USED
CIRCUITS; IE., THE "END OF RUN" IS OMITTED.
B. A TWO-PART NUMBER IS USED FOR MOST LIGHTING AND SOME POWER DISTRIBUTION
C. CONTROL CIRCUIT NUMBERS CORRESPOND TO THE NUMBER OF THE CONTROLLED
POWER CIRCUIT; EG., CQ1-c1-K WOULD CONTROL CQ1-q1-K.
E. CIRCUITS TO DEVICES FORMING AN INTEGRAL PART OF TERMINAL EQUIPMENT
RECEIVE THE TERMINAL EQUIPMENT DESIGNATION (E.G. THE CIRCUIT TO CT'S IN
CIRCUIT BREAKER XW1 COULD BE DESIGNATED SJ4-a1-XW1). CIRCUIT TO CT'S IN
IS A CIRCUIT GOING TO FLOWMETER NO. 2).
CIRCUIT DEVICES RECEIVE THE DESIGNATION ASSIGNED TO DEVICE (I.E. SJ4-c1-FM2
CONTAINED WITHIN THE CONDUIT.
D. CONDUIT NUMBERS ARE GENERALLY IDENTICAL TO THE FIRST CIRCUIT
