The current project has added <br />panels and transformers on the Normal Branch, has added panels to the Critical Branch, and has <br />added circuits to the existing Life Safety Branch panels that were installed as part of the original <br />construction. All generators and automatic transfer switches serving the 9th floor were installed as <br />part of the original D-Wing construction. <br />The following is a summary of the testing of the emergency distribution system that was <br />conducted as part of the original construction project: <br />* 3rd party inspection of all switchboards, panel boards, and all breakers 100-amp and larger. <br />• Black Building Test (3X) conducted with Utility Plant generators (during test, utility power <br />disconnected) as part of overall building commissioning <br />o Verified egress lighting operation <br />o Verified exit sign operation <br />• Receptacle testing by Electrical Contractor in accordance with NFPA 99 <br />As part of the 9th floor project, the following testing has been performed: <br />• 3rd party inspection of all new panelboards and all new breakers 100A and larger <br />• Receptacle testing by Electrical Contractor in accordance with NFPA 99 <br />In addition to the testing during construction projects, the hospital conducts monthly generator <br />tests in accordance with code. The transfer switches that serve D-Wing are closed -transition type <br />which is a make -before -break arrangement that allows the loads to remain connected during <br />transfer from utility power to generator power. This allows the hospital to test the generators with <br />no impact to patient care services in the building. <br />Let me know if there are additional questions or if you need additional information on the testing. <br />11 <br />
