This document is a technical specification and wiring diagram for a Cathodic Protection System (CPS) Electrical Element designed for the Coastal Hydrographic Survey Ship (TAGS 51/52), prepared for the Department of the Navy Naval Sea Systems Command in Washington, D.C. The specification was developed by Halter Marine Inc. (P.O. Box 291266, New Orleans, LA 70189) under Contract No. N00024 89-C-2019, with the document number GBB-GG34907.

The technical drawing provides a comprehensive bill of materials and detailed wiring schematic for the cathodic protection system installation. Key components include an electrocatalytic controller rated at 440VAC, 3Ø, 60Hz, 300A at 22VDC; multiple impressed current supply cables (SSGU series) ranging from 50 to 100 feet in various configurations; reference anodes at fore and aft locations; junction boxes with brass surfaces; lug solders (Sherman type); grounding brackets; and cable assemblies. The general notes specify that actual cable lengths shall not exceed 150 feet for CPS-1 and CPS-2 (55GU-75) systems and 100 feet for CPS-3 and CPS-4 (55GU-50) systems. All grounding leads must be as short as possible, with a maximum length of 7½ feet for shaft and rudder post ground leads. Anode cables are to be routed via the shortest practicable path. The document is Revision A, Sheet 1 of 6, dated 2-9-90, with scale noted as "None."
