About this file
This is an electrical demolition plan sheet (EB201) for the California Department of Corrections and Rehabilitation (CDCR) at California State Prison, Los Angeles County located in Lancaster, CA. The document is part of a roof replacement project for Facility A 270 Housing Unit Building 334, specifically detailing the electrical demolition plan for the roof and partial second level. The project is being managed by M. Neil Engineering and is scheduled for implementation in August 2023, with working drawings dated 08/29/2023 and 09/13/2023.
The electrical demolition plan provides detailed instructions for removing and replacing existing electrical infrastructure, including conduits, junction boxes, and electrical circuits associated with HVAC and electrical equipment on the rooftop. Key specifications include placing existing electrical circuits in a "safe-off" condition, removing portions of existing conduits and wiring, replacing junction boxes and flex conduits, and maintaining circuit continuity. The plan includes specific notes about preserving fire alarm devices, replacing non-GFCI receptacles, and ensuring that new electrical installations match existing wiring sizes, quantities, and types. The document has received approval from the Office of the State Fire Marshal on 10/10/23 with the approval number 23-0002.

NUMBERED NOTES
GENERAL NOTES
1. PLACE ALL EXISTING ELECTRICAL CIRCUITS FEEDING EXISTING HVAC AND ELECTRICAL EQUIPMENT ON
ROOFTOP IN A "SAFE-OFF" CONDITION, PRIOR TO CONSTRUCTION. NO NEW LOADS ADDED TO
CIRCUITS.
2. REMOVE PORTIONS OF EXISTING CONDUITS AND WIRING NECESSARY TO RE-ROOF EXISTING
BUILDING.
3. DO NOT DAMAGE DURING CONSTRUCTION AND REUSE ALL EXISTING CIRCUITS, PROVIDE NEW HVAC DISCONNECTS, PROVIDE NEW WEATHERPROOF GFCI SERVICE RECEPTACLES TO REPLACE EXISTING
RECEPTACLES FOR REMODEL.
4. REMOVE EXISTING JUNCTION BOXES AND FLEX CONDUITS BACK TO ROOF PENETRATION POINT, AND DO NOT REUSE. REPLACE ALL ABOVE ROOF CONDUITS WITH NEW - WIRING 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 METAL CONDUIT TERMINATION AT THE MECHANICAL
EQUIPMENT .
5. DO NOT DAMAGE HVAC DUCTS WITH DUCT DETECTORS. MAINTAIN FIRE ALARM DEVICE AND CIRCUIT
DURING CONSTRUCTION.
6. DO NOT DAMAGE WP SERVICE RECEPTACLE BACK BOXES. REMOVE ANCHORING, AS NEEDED, TO
ALLOW MOVEMENT DURING ROOFING REPAIR. MAINTAIN CIRCUIT CONTINUITY AND RECEPTACLE
FUNCTIONALITY AFTER CONSTRUCTION.
7. REPLACE JUNCTION BOXES. REPLACEMENT BOX TO MATCH EXISTING TYPE AND SIZE.
EXISTING MECHANICAL UNIT TO BE DISCONNECTED FOR ROOF REPAIR. COORDINATE WITH
MECHANICAL. REINSTALL USING NEW ELECTRICAL CONDUIT, CONDUCTORS AND DEVICES.
CONDUIT SIZE, WIRING SIZE, QUANTITY AND TYPE SHALL MATCH EXISTING. SEE REMODEL PLAN
"1/EB301".
EXISTING NON-GFCI RECEPTACLE TO BE REPLACED. SEE REMODEL PLAN "1/EB301".
EXISTING RSC LOCATED ON ROOF TO BE REMOVED TO ALLOW FOR RE-ROOFING. EXISTING
CONDUIT TO BE REPLACED WITH NEW AFTER NEW ROOF IS INSTALLED. MAINTAIN CONTINUITY OF EXISTING CIRCUITING RUNNING IN THE THE CONDUIT. FIELD VERIFY QUANTITIES AND SIZES.
EXISTING RSC LOCATED ON TOP OF PARAPET TO BE REMOVED TO ALLOW FOR RE-ROOFING.
EXISTING CONDUIT TO BE REPLACED WITH NEW AFTER NEW ROOF IS INSTALLED. MAINTAIN
CONTINUITY OF EXISTING CIRCUITING RUNNING IN THE THE CONDUIT. FIELD VERIFY QUANTITIES
AND SIZES.
EXISTING RSC LOCATED ON PARAPET WALL TO BE REMOVED TO ALLOW FOR RE-ROOFING.
EXISTING CONDUIT TO BE REPLACED WITH NEW AFTER NEW ROOF IS INSTALLED. MAINTAIN
CONTINUITY OF EXISTING CIRCUITING RUNNING IN THE THE CONDUIT. FIELD VERIFY QUANTITIES
AND SIZES.
EXISTING WALL MOUNTED LIGHT FIXTURE TO BE REMOVED
EXISTING BEACON MOUNTED HIGH ON WALL TO REMAIN. PROTECT EXISTING BEACON AND
ASSOCIATED MOUNTING EQUIPMENT DURING CONSTRUCTION. IF EQUIPMENT MUST BE
TEMPORARILY RELOCATED FOR NEW ROOF INSTALLATION, THEN REINSTALL AFTER ROOF
INSTALLATION. MAINTAIN ALL EXISTING CONNECTIONS.
