Distribution Equipment, and Branch Circuit Panelboards

A. The distribution panelboards and branch circuit panelboards will have copper phase, neutral and ground buses. Load centers will not be allowed and multi-section, such as double-section, panelboards will not be allowed. The maximum number of circuit breakers in a panelboard will not exceed 42. The neutral bus in each panelboard will be 200% fully rated and have an adequate number of terminals to accept one neutral conductor termination for each branch circuit. All circuit breakers will be bolt-on type and fully rated for the available short circuit fault current. Circuit breakers will be thermal-magnetic, except that fully adjustable electronic-trip circuit breakers will be used when necessary for fault and overcurrent coordination.

B. New transformers will have copper windings and be K13 rated.

C. See one-line diagram for a general system arrangement.

D. Each TR minimum panelboard requirement will be two dedicated electrical branch circuit breaker panelboards, 120/208v, 3-phase, 100 ampere main shunt trip circuit breaker, with 48 spaces.

Loads will include, but limited to, convenience receptacles, rack receptacles, HVAC (including split systems).

E. Distribution Equipment and Branch Panelboards with a significant number of nonlinear loads will have the neutral sized for the larger of either 1.73 times the phase conductor or one size larger than the phase conductor. The neutral feeding these panels will be counted as current carrying conductors.

Surge Protection Devices

A. Externally mounted Type 1 or Type 2 surge protective devices will be provided at the main distribution panelboard and as necessary, at panelboards serving electrically sensitive equipment.

C. All meters will be monitored by the mechanical BAS system for kWH, Peak VA, and instantaneous VA.

Grounding and Bonding

A. The existing electrical system is grounded in accordance with the National Electrical Code.

B. An equipment grounding conductor will be routed with branch circuit and feeder conductors and bonded to a ground bus or ground lug at each end and in all pull boxes and cabinets.

Wiring Devices and Branch Circuits

A. Wiring devices and branch circuits will be provided for all equipment and areas as required in the scope of work. The convenience outlets will be heavy-duty specification grade, 20 ampere, 125 volt rated duplex devices, except where heavy duty hospital grade is required by NFPA requirements.

Wiring and Raceways

A. All wiring (120 volts and above) will consist of individual conductors run in raceway. All conductors will be copper. Conductor insulation will THHN-THWN or XHHW-2, as required for the application, with a minimum size of #12 AWG except for control wiring which may be #14 AWG and special systems such as public address will be minimum size as required by the respective manufacturer and other conditions such as voltage drop.

B. All interior conduits will be EMT and no smaller than ½-inch in diameter.

C. Flexible metal conduit will only be used for light fixture whips and connections to motors and other vibrating equipment; lengths will not exceed six feet. Liquid tight flexible metal conduit will be employed were exposed to moisture or outdoors. Flexible metal cables, including AC and MC cables, are prohibited.

D. All interior electrical equipment will be NEMA 1 construction.

DIVISION 28 SECURITY

A. The following design development narrative describes the security system requirements for the EHRM Infrastructure Upgrades project at Harry S. Truman Memorial Veteran’s Hospital campus based on our understanding of the project scope and applicable codes, criteria, and regulatory standards.

A. The security system will be in accordance with the following standards and design guidelines.

The specific requirements of these standards are not included in this document.
