A damp location is an interior location normally subject to dampness or condensation, or an exterior location protected from weather and not subject to saturation with water. Damp locations include over bathtubs, indoor pools, covered porches, and like locations.
Emergency inverters keep your lights on in uncertain situations. Interruptible inverters have a slight delay before power is restored while uninterruptible inverters maintain the power load, without fluctuation, during an outage.
Emergency light ballasts are devices that allow normal fluorescent lights to double as an emergency light by providing battery power to one or two lamps after electrical power is lost. These ballasts operate for a minimum of 90 minutes in a situation where electricity is lost, the same length of time that emergency lighting fixtures normally operate.
