21 Underground

22 Direct Buried Warning tape Cable Sand

23 Aerial

24 Interbuilding Pathway Variables applicable codes aesthetics of building and surrounding location type and use of building future growth difficulty of adding pathways in the future type, size, length, and number of cables to be installed separation from electrical facilities physical possibilities (ground topologies, soil conditions, obstructions) an alternate entrance use of corrosion resistant pathways and associated hardware
