ATT 8.3 Electrical Manholes Layouts_Dsgn Rev 01.pdf

These are Electrical Manhole Layout design documents for the Navy South Substation, located east of Hampton Boulevard. The documents detail eight variations of Manhole Layout #3743, each with specific electrical cable routing configurations.

Each layout shows a 192" long by 96" wide by 120" high manhole with a 31 3/4" lid size and 44" throat. The layouts include two primary cable types: S5 (Navy South CB 5 to SW 232 Way 1) and S9B (SW 301 Way 3 to SW 222 Way 4), both at 35KV with 750MCM cable size and EPR insulation. The documents indicate spare conduits, splice locations, and cable routing between various Electrical Manholes (EMH), with no specific condition notes and a standard opening size of 29 3/4". The layouts are labeled with suffixes I, K, L, M, N, P, Q, and R, suggesting multiple interconnected electrical infrastructure points.
