About this file
This is an Electrical One Line Diagram and Panel Schedule document prepared by SGM Engineering for Volusia County Government's DeLand Courthouse Central Energy Plant (CEP) Upgrades project. The electrical design, prepared by engineer Justin L. Mundell (FL License No. 70700), outlines the power distribution system required to support the chiller system replacement and associated mechanical and electrical upgrades at the courthouse facility located at 101 N. Alabama Avenue, DeLand, FL 32724. The diagram specifies two main distribution panels (MDP-A and MDP-B), each rated at 277/480V, 3-phase, 4-wire service with 3000-ampere capacity. MDP-A carries a connected load of 3,019.5 kVA with a demand load of 2,189.8 kVA (2,635 amps), while MDP-B carries a connected load of 2,946.9 kVA with a demand load of 2,045.7 kVA (2,462 amps). The system includes multiple circuit breakers ranging from 60 amperes to 1,200 amperes supporting lighting, receptacles, HVAC components, chillers, and emergency mechanical systems. The design document is issued as 100% Construction Documents dated November 27, 2024, with engineering stamps indicating professional certification and compliance with Florida engineering standards.
The electrical design incorporates comprehensive load calculations for both panels, with specific demand factors applied to lighting (1.0), receptacles (0.5), computer/receptacle loads (0.65), HVAC systems (0.9), and emergency mechanical systems (0.7). Technical specifications require all feeders to maintain less than 2% total voltage drop and all branch circuits to maintain less than 3% voltage drop in compliance with electrical code standards. The diagram distinguishes between existing systems to remain (indicated in light color) and systems to be removed (indicated in dark color), with coordination requirements across all construction trades. Additional requirements include protection of building systems during construction, maintenance of service continuity, field verification of existing conditions prior to demolition, and wall patching to match existing conditions. The design incorporates surge protection for critical loads and references general notes, symbols, and specifications detailed on sheets E001, E501, and E701 of the construction document set.

GENERAL NOTES:
a. REFER TO GENERAL NOTES AND SYMBOLS ON SHEET E001
b. REFER TO BOOK SPECIFICATIONS.
c. ALL FEEDERS ARE TO HAVE LESS THAN 2% TOTAL VOLTAGE DROP
AND ALL BRANCH CRICUITS SHALL HAVE LESS THAN 3% VOLTAGE
DROP.
d. PROTECT BUILDNG SYSTEMS AT ALL TIMES DURING
CONSTRUCTION. MAINTAIN CONTINUITY OF SYSTEMS TO REMAIN.
IF NECESSARY PROVIDE TEMPORARY OR PERMANENT RE-WIRING
TO RECONNECT SYSTEM DEVICES TO THE BUILDING SYSTEMS SO
SERVICES ARE NOT INTERRUPTED DURING CONSTRUCTION.
e. COORDINATE WORK WITH ALL OTHER TRADES BEFORE ANY
ROUGH-INS. FIELD VERIFY EXISTING CONDITIONS PRIOR TO
DEMOLITION.
f. ALL SYMBOLS SHOWN IN "LIGHT" COLOR INDICATE EXISTING TO
REMAIN; NO WORK REQUIRED UNLESS NOTED OTHERWISE.
g. ALL SYMBOLS SHOWN IN "DARK" COLOR INDICATE TO BE
REMOVED, UNLESS NOTED OTHERWISE.
h. PATCH WALLS AFFECTED BY DEMOLITION OR NEW WORK AS
REQUIRED TO MATCH EXISTING CONDITIONS.
