We are running some underground conduit in ductbank between some buildings. One building is much higher than the other. I am worried that water, if it gets into the conduit by any means, will run down and get into the electrical gear at the downhill end. How could water get in, you say? well, let me count the ways:
Condensation build up over time
Unplanned flood at the uphill building due to repairs by 3-stooges Mechanical co. inc.
GroundWater infiltration into underground conduit due to poorly made joints
Is it common to put in water control features in concrete ductbank, such as a weep-hole at the lowest point in a concrete ductbank run, or would a weep hole in conduit just allow more water in, or worse violate the NEC?
