About this file
This is a Questions and Answers document for federal contract opportunity Notice ID W912LD26Q0005, Amendment 0001, addressing connector specifications for a ground power unit project.
The document clarifies that brand-name references in the solicitation are performance-based rather than brand-specific requirements. For the input connector, vendors must source a cable terminating with a Hubbell HBL4100PS1W plug (3-pole, 4-wire configuration) meeting these specifications: 4-conductor configuration, 100 amp amperage rating, #2 AWG wire gauge, 600V voltage rating, and flexible portable cord suitable for outdoor/wet locations (SOOW or equivalent). The document additionally identifies the matching wall receptacle as HBL4100RS1W for a 208V input connection. For the output connector, the requirement specifies a 6-pole Molded Blackhawk connector rated for 115/200V AC at 400Hz, with Aircraft Receptacle P/N MS90362-3 (aircraft-side connector) and Ground Power Unit Plug P/N MS25486 (power cart-side mating plug). Vendors are directed to use these specifications and part numbers to ensure compatibility when sourcing components, with equivalents acceptable provided they meet the stated performance and compatibility standards.

Notice ID: W912LD26Q0005
Amendment: 0001
Interested Vendors Q & A
1. In regards to the 3 Phase Hubble Connector (for input) and the Molded Blackhawk Connector (for output), Could you please confirm whether these references are intended to be brand name specific requirements, or if equivalent connectors meeting the same performance and compatibility standards are acceptable?
“3 Phase Hubble Connector” for input: The current cable terminates with a Hubbell HBL4100PS1W plug. Based on the specifications of this plug and the application, the required cable must meet the following criteria:
• Conductors: 4-Conductor (to match the 3-Pole, 4-Wire plug
• Amperage Rating: 100 Amps
• Wire Gauge: #2 AWG
• Voltage Rating: 600V
• Cable Type: Flexible Portable Cord suitable for outdoor/wet locations (e.g., SOOW or equivalent)
“Molded Blackhawk Connector” for output: Here are the key details for the required components:
• Power Type: 115/200V AC, 400Hz
• Connector Style: 6-pole
• Aircraft Receptacle P/N: MS90362-3 (This is the connector on the aircraft.)
• Ground Power Unit (GPU) Plug P/N: MS25486 (This is the mating plug required on the power cart side.)
Please use these part numbers to ensure compatibility when sourcing the correct connector for your ground power unit.
2. In reviewing the referenced solicitation, you are requiring a Hubbell plug be attached to the input cable. Assuming you are using an existing 208 V Hubbell input connection/receptacle, we need to know the matching plug part number. Please advise for proper quoting.
Existing wall plug part number is: HBL4100RS1W (3 pole 4 wire (3P4W))
