Here voltage drop for 70 Sq.mm Cable (5.8 %) is higher than define voltage drop (5%) so either select higher size of cable or increase no of cable runs. This is a good goal to shoot for when sizing the conductors for an underground cable. The process of the size calculation method consists of six steps. The National Electrical Code (NEC) recommends a maximum voltage drop of 3 percent for individual household circuits (known as branch circuits). 480V electrical motor wiring data - NEMA amps, starter size, HMCP size for motors ranging 1/2 to 500 hp. If we select 2 runs, than voltage drop is 2.8% which is within limit (5%) but to use 2 runs of cable of 70 Sq.mm cable is not economical, so its necessary to use next higher size of cable. Acceptable Power Loss . Electrical Cable In the very first step, we collect data about cable, load, and environmental conditions. Underground cable fault (PHOTO CREDIT: scantekgroup.com.au) To reduce failures related to electrochemical treeing, a utility can install surge protection on riser poles (transitions from overhead to underground), can purchase tree-retardant cable, and can test cable reels before accepting them from the manufacturer. A 3-phase sub-main circuit having a design fundamental current of 100A is to be wired with 4/C PVC/SWA/PVC cable on a dedicated cable tray. Maximum electrical motor cable length vs. power. Other electrical wire burial depths from Snohomish - cited below. Metal conduit carrying SEC - at least 6 inches below soil top; Metal conduit carrying SEC - 4 inches under a 4-inch concrete slab.
