Connectors designed for field termination

Vantage Victory series explosion proof connectors set the standard for wastewater pump stations at US Forest Service installations.

Section: 62.91 of The Forest Service Handbook, FSH 7409.11 (SANITARY ENGINEERING AND PUBLIC HEALTH HANDBOOK 12/76 WO AMENDMENT 5) defines the agency's policies, practices, and procedures as they pertain to Hazardous (Class I, Division I) Locations per the National Electric Code 500-4.

As a result, Vantage connectors are defined in Specification 16115,

  • NEMA 7 Dry Location - Explosion proof Circuit Breaking Plugs and Receptacles. (Section 2.14)
  • NEMA 7 Sewage Pump Station Wet well - Explosion proof Circuit Breaking Plugs and Receptacles. (Section 2.15)
  • NEMA 4 Disconnect Plugs And Receptacle. (Section 2.16)
