A client has a 3 phase incoming supply as in picture 200amp head
160a fuses as fitted by dno when 100a kept blowing on startup of irrigation pump (60hp) 129a start up added to normal daily load of 30a per phase as you can see its a direct load meter rated at 20-120 aamps we feel he should have ct metering and appropriate switch gear, but it dno's meter and fuses so I guess it's upto them
all comments welcome
