About this file
This document is an electrical roof remodel plan for Facility A 270 Housing Unit Building 334 at California State Prison, Los Angeles County, prepared by M. Neil Engineering for the California Department of Corrections and Rehabilitation (CDCR). The plan details electrical modifications for a roof replacement project, specifically focusing on extending existing electrical circuits, replacing conduits and wiring, reinstalling mechanical units, and updating electrical equipment. The project is located at 44750 60th Street West in Lancaster, California, and involves precise electrical infrastructure updates for the housing unit building.
The electrical plan includes comprehensive instructions for maintaining existing circuit continuity and equipment functionality, with specific requirements for replacing disconnects, manual starters, receptacles, and junction boxes. Key specifications include using new EMT with compression fittings, liquid-tight flexible metal conduit, and ensuring all new electrical components match existing voltage, phase, and current ratings. The drawings are dated August 29, 2023, with working drawings submitted on August 31, 2023, and have received approval from the Office of the State Fire Marshal on October 10, 2023. The project number is 5843.10, and the engineering firm's project number is 21318.21.

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"
NUMBERED NOTES
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.
EXISTING RSC LOCATED ON ROOF TO BE REINSTALLED AFTER ROOFING REPLACEMENT. FIELD
VERIFY QUANTITIES AND SIZES. REFER TO DETAIL "1/E9.001" ON SHEET E9.001.
EXISTING RSC LOCATED ON TOP OF PARAPET TO BE REINSTALLED AFTER ROOFING
REPLACEMENT. FIELD VERIFY QUANTITIES AND SIZES. REFER TO DETAIL "1/E9.001" ON SHEET E9.001.
EXISTING RSC LOCATED ON PARAPET WALL TO BE REINSTALLED AFTER ROOFING REPLACEMENT.
FIELD VERIFY QUANTITIES AND SIZES. REFER TO DETAIL "1/E9.001" ON SHEET E9.001.
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".
