ABSTRACT:
In hilly areas, building below the level of flooded manholes or secondary distribution boxes are often damaged by water entering the electric meter enclosure through the service conduit. For eliminating drain water from a service conduit before it reaches a meter enclosure, a drain pipe is installed in the conduit below the meter enclosure. The drain pipe must not be accessible to any probing and therefore has several spaced, oppositely and alternately positioned vanes in the bore with each vane covering over half the area of the bore.
