Duraline’s Fire Power System are wet location wiring devices and are engineered to eliminate dangerous GFI nuisance tripping and make electrical power available at the site of the emergency without any worry to the first responder. The system is engineered to withstand abuse including high pressure hosedown. Connectors, plugs, etc. can’t be crushed by other fire vehicles as other conventional connectors can. It’s designed to enhance GFCI safety, even when submerged in water.
