FAQ: Which Champion Fiberglass conduit should be used in Direct Buried applications?
Direct Buried (or DB quality) applications should utilize UL Listed conduit. Use Standard Wall for 3/4″ – 4″ diameter, and Medium Wall for 5″ and 6″ (UL designates Champion Fiberglass MW for 5″ and 6″ as SW). For very deep trenches, special soil conditions or where high rate of compacting can be expected, an even heavier wall should be selected. Please contact Champion Fiberglass with questions on any of the above situations.
