Back boxes in the Eaton Crouse-Hinds Arktite series (e.g., AJ, AJC, AJX, AR) are enclosures that mount Arktite receptacle housings (20A-400A) to surfaces or conduit systems, providing wiring access and environmental protection. They’re designed for flexibility, supporting various hub sizes, configurations (dead-end, through-feed, angle), and mounting options for industrial applications, including hazardous (EPC/EPCB) and non-hazardous (WSR/WSRD, WSQC) settings.
Description
Key Features
- Compatibility: Works with Arktite receptacles (e.g., WSR, WSRD, WSQC, EPC, EPCB) and plugs (APJ, NPJ, DP).
- Materials:
- 20A-200A: Copper-free cast aluminum (corrosion-resistant).
- 400A: Feraloy iron alloy (high strength).
- Hub Sizes: Range from 1/2″ to 2-1/2″, depending on receptacle amperage and conduit needs.
- Types:
- AJ: Standard dead-end or through-feed boxes.
- AJC: Compact through-feed boxes (e.g., for 60A-150A).
- AJX: Extra-large boxes for complex wiring or higher amperages.
- AR: Angle or round flange boxes for specific mounting.
- Mounting: Surface, panel, or semi-flush options with lugs or brackets.
Applications
- Non-Hazardous: WSR/WSRD (factories, docks), WSQC (warehouses, outdoor sites).
- Hazardous: EPC/EPCB (refineries, chemical plants with flammable gases/dusts).

*Notes:
- Hub Sizes: Match conduit needs (e.g., 1″ for 30A, 1-1/2″ for 100A, 2″ for 200A), consistent with EPC/EPCB hub references.
- Cat. # Examples: AJ28 (20A-30A, 1″ dead-end), AJC108 (60A-100A, 1-1/2″ through-feed).
- Compatibility: EPC/EPCB inferred from amperage (e.g., EPC306 ≈ 30A); WSR/WSRD/WSQC based on catalog matches.*
