The Contractor shall coordinate with the temporary HVAC unit provider to obtain the electrical characteristics and installation requirements and provide all required electrical connections. The existing power panels, distribution panels and/or motor control centers currently feeding the existing mechanical equipment may be used for power to the temporary mechanical equipment only after the existing units have been fully disconnected and a 30-day meter reading has been performed. The meter reading shall be reviewed and approved by the COR and A/E prior to connecting the temporary unit. The Contractor shall verify the voltage and circuit breaker requirements of the temporary units and provide power from the appropriate electrical distribution equipment. The Contractor shall provide any new circuit breakers or motor control protectors required for the temporary unit connections. Wire sizes and installation methods shall comply with NEC.
