About this file
This electrical drawing is a roof plan for the California State Prison, Los Angeles County (LAC), prepared by M. Neil Engineering for the California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division. The document specifically details an electrical remodeling plan for roof replacement in Phase 1, focusing on Typical 270 Housing Unit buildings (Buildings 331-349), with the project dated August 29, 2023 and working drawings set for August 31, 2023. The plan includes extensive electrical infrastructure modifications, such as extending existing circuits, replacing conduits and wiring, reinstalling mechanical units, and updating electrical equipment like disconnects, junction boxes, and receptacles.
The electrical drawings show comprehensive roof-level electrical work across multiple prison buildings, with specific requirements including replacing all above-roof conduit and wiring, maintaining existing circuit continuity, installing new EMT with compression fittings, and ensuring all new electrical components meet current code standards. The project involves precise coordination with mechanical and plumbing contractors, replacement of weatherproof receptacles, and ensuring all electrical installations are compatible with existing infrastructure. The drawings have received approval from the Office of the State Fire Marshal on October 10, 2023, with a final approval date of November 20, 2023, indicating the project has passed necessary regulatory inspections and meets required safety standards.

NUMBERED NOTES
GENERAL NOTES
1. EXTEND EXISTING CIRCUITS, WIRING AND CONDUITS AND RECONNECT TO EXISTING RELOCATED
MECHANICAL, LIGHTING AND ELECTRICAL EQUIPMENT. REUSE SAME CIRCUIT TO FEED SAME
MECHANICAL AND ELECTRICAL EQUIPMENT, AS PRIOR TO CONSTRUCTION. MAINTAIN EXISTING
CIRCUIT CONTINUITY AND EQUIPMENT FUNCTIONALITY. ALL ABOVE ROOF CONDUIT AND WIRING MUST BE REPLACED WITH NEW . WIRE SIZE, QUANTITY AND TYPE SHALL MATCH EXISTING. SPLICE IN POWER WIRING IS NOT ACCEPTABLE. NEW CONTROL WIRING TO HVAC EQUIPMENT MAY ONLY BE INSTALLED
FOR THE RUN FROM THE EQUIPMENT CONTROL PANEL TO THE NEAREST EXISTING TERMINATION
POINT OR SPLICE LOCATION INSTALL NEW EMT WITH COMPRESSION FITTINGS AND LIQUID-TIGHT
FLEXIBLE METAL CONDUIT TERMINATION AT THE MECHANICAL EQUIPMENT.
2. REPLACE EXISTING DISCONNECT/MANUAL STARTERS WITH NEW TO FEED SAME HVAC, AS PRIOR TO
CONSTRUCTION. NEW DISCONNECT/STARTER TO MATCH EXISTING TYPE, VOLTAGE, PHASE, AND
CURRENT RATING. REPLACE ALL EXISTING WEATHERPROOF GFCI SERVICE RECEPTACLES WITH NEW
WP/WR/GFCI RECEPTACLES THAT ARE TO CURRENT CODE.
3. PROVIDE NEW WEATHERPROOF, NEMA 3R JUNCTION BOXES AND WATERTIGHT FLEX CONDUITS FOR EACH MECHANICAL AND ELECTRICAL EQUIPMENT. KEEP EXISTING CONDUIT PENETRATIONS AT THE
SAME LOCATIONS AS PRIOR TO CONSTRUCTION.
4. PROVIDE BLOCKING AND CHANNELS TO CONDUIT RACEWAY AS NEEDED ON ROOFTOP. COORDINATE
WITH MECHANICAL AND PLUMBING CONTRACTORS FOR JOINT USE BLOCKING. SEE "2/E9.001"
REINSTALLED MECHANICAL UNIT. RECONNECT EXISTING POWER AFTER ROOFING REPLACEMENT.
SEE DETAIL "1/E9.001" ON SHEET E9.001.
REPLACE EXISTING RECEPTACLE WITH NEW GFCI, WEATHER PROOF, WEATHER RESISTANT
RECEPTACLE.
LOCATE AND INTERCEPT EXISTING CIRCUIT AND CONTROLS BELOW ROOF DECK. SPLICE AND
EXTEND TO RAISED EQUIPMENT AND RE-CONNECT. TYPICAL FOR ALL MECHANICAL UNITS
MOUNTED ON RAISED ROOF.
PROVIDE NEW GFCI, WEATHER PROOF, WEATHER RESISTANT RECEPTACLE WITH METAL
WHILE-IN-USE COVER. CONNECT TO THE EXISTING ROOF RECEPTACLE CIRCUIT.
ALL CONDUIT RUN EXPOSED ON THE ROOF SHALL BE SUPPORTED PER DETAIL "2/E9.001".
SUPPORT SPACING SHALL BE PER DETAIL "2/E9.001", NOTES 1 AND 2.
