Protective Cap for 400 A Male Devices

This blue thermoplastic elastomer cap fits male wiring devices rated at 400 A and compatible with Series 16. It provides a NEMA 12, 3R, and 4X enclosure rating to shield connections from dust, rain, and hose-directed water. The cap measures 2.78 in long and 1.48 in wide for a secure fit over the device interface.

NEMA 12 3R 4X Environmental Limits

The enclosure rating protects against circulating dust, falling dirt, and dripping non-corrosive liquids in indoor and outdoor locations. It also resists corrosion and windblown dust while withstanding water projected from a nozzle. The cap does not protect against prolonged submersion or high-pressure steam cleaning beyond the rated tests.

Snap-On Installation and Common Issues

The cap installs by pressing it onto the male device until the thermoplastic elastomer grips the housing. No tools are required for fitting or removal. Dirt or debris on the device face can prevent a full seal, and overstretching the material during removal may reduce retention over repeated cycles.
