A low point drain for draining accumulated water from electrical conduit systems that are located in non-hazardous environments is disclosed. The drain includes a threaded coupling suitable for connection to a tapped opening in an electrical conduit, or a conventional "T" or elbow fitting or an electrical enclosure or junction box. The drain also includes an end cap attached to the other end of the coupling, a safety washer and a screen assembly that is retained within the end cap. The end cap has an interior lip that defines an opening through which the water may drain. The screen assembly includes a grommet that is held securely against the coupling end and a frustoconical screen that protrudes through the end cap opening. When the drain is installed at a low point in the conduit system, condensate that forms in the system flows out the drain aperture and screen by the action of gravity. The screen assembly also serves to exclude vermin and debris and provides a visual indication when rust or debris has accumulated to an extent requiring that the drain be cleaned.
