ELECTRICAL TRENCHING
Senior Design
Embedded Files
When a project requires electrical trenching or an overhead span, there are extra design considerations to be aware of. This includes extra planning for trench paths, trench depth, conduit runs/direct burial and manual adjustments to electrical calculations in addition to additional callouts on the BOM. This training will walk you through each common electrical trenching scenario.
