2.0 GROUND POWER UNIT EQUIPMENT SPECIFICATIONS 2.1 GENERAL REQUIREMENTS

1) The Ground Power Unit (GPU) shall be capable of providing dual output power to an aircraft docked to the PBB at voltages of 90kVA 400Hz Vac simultaneously on both output cables. The unit shall be mounted under the cab of the PBB; utilizing the mounting holes of the existing Jetway JP2 120kVA dual output 400Hz GPU.

2) The unit design shall be based on a Pulse Width Modulated (PWM) design for maximum efficiency. 3) The PBB at Gate B37 has a 250 amp adjustable circuit breaker mounted in the PBB disconnect cabinet

located at the PBB Rotunda (See EXHIBIT II). This circuit breaker is currently utilized for the main power to the PBB and to the existing 120kVA dual output GPU. The existing 1/0 AWG power cable in the PBB cable carrier used for the PBB and GPU is insufficient for the service load requirements of the PBB and the new 180kVA 400Hz Dual Output GPU. Therefore, the Contractor will be required to supply an additional adjustable 250 amp circuit breaker for the 180kVA 400Hz Dual Output GPU power. Input power for this new breaker shall be tapped off the existing PBB/GPU breaker. This new breaker shall be capable of being Locked or Tagged out. a) The existing PBB/GPU breaker will then be dialed down and this electrical circuit will only be used for

PBB power. a) The existing 2-breaker shut off linkage shall be reused for the PBB only and PCAir disconnects. A new

handle shut off mechanism will be supplied for the new adjustable 250 amp GPU circuit breaker. The shut off handle shall be mounted on the exterior of the SST disconnect cabinet door and shall engage the circuit breaker’s shut off mechanism when the SST disconnect cabinet door is closed.

b) The existing 1/0 AWG power cable in the PBB cable carrier will be reused for PBB power only. The Contractor shall supply a new 3/0 AWG, 3C-W/G, 600V SO cord input power cable and aluminum dogleg, to provide input power for the new 180kVA 400Hz Dual Output GPU. SO cord must be Class M Stranding, UL listed, sunlight resistant and marked every meter with UL requirements.

b) The contractor shall remove the old GPU input power cable from the C2 junction box and plug the hole in the C2 junction box (See EXHIBIT IV).

4) The PBB at Gate B47 has separate circuit breakers mounted in the PBB disconnect cabinet located at the PBB Rotunda for the PCAir, GPU and PBB (See EXHIBIT II). The GPU circuit breaker is currently set to 125 amps. It can be dialed up to the 200 amps required for the new 180kVA 400Hz Dual Output GPU. The existing 2 AWG flat pack power cable in the PBB cable carrier used for the 120 kVA 400Hz GPU is insufficient for the service load requirements of the new 180kVA 400Hz Dual Output GPU. Therefore, the Contractor will be required to supply a new input power cable from the existing GPU circuit breaker in the PBB disconnect cabinet to the new 180kVA 400Hz Dual Output GPU. a) The existing GPU breaker will be dialed up to 200 amps. c) The Contractor shall supply a new 3/0 AWG, 3C-W/G, 600V SO cord input power cable and aluminum

dogleg, to provide input power for the new 180kVA 400Hz Dual Output GPU. SO cord must be Class M Stranding, UL listed, sunlight resistant and marked every meter with UL requirements.

b) The Contractor shall disconnect the existing 2 AWG flat pack cable from the GPU breaker in the PBB Disconnect Cabinet and from the existing 120kVA 400Hz GPU. The ends of the cable shall be shrink wrapped, coiled and secured to the PBB Rotunda Rigid Frame and the PBB C Tunnel (See EXHIBIT IV).

5) The new 180kVA GPU shall utilize the existing Pendant Control (s) and PBB interlock.



6) The GPU design proposed by the Contractor shall have been IN USE for a minimum of five (5) years. Specific prior projects documenting compliance to this requirement shall be supplied with the Contractor’s Proposal. Contact information shall also be supplied for these projects.
