Three Phase Electrical Wiring Installation In Home Nec Iec Tutorial Generally, electric supply and service providers install a single phase energy meter when load is less than 7.5kw (10hp) in domestic areas (consumer unit for home). if the limit is exceeded, then it’s recommended to install a 3 phase energy meter for consumer units. when load exceeds from 7.5 kw, then 3 phase electrical wiring is recommended. Fig 2: electrical wiring diagram of three phase & single phase consumer unit with rcd in multi storey bulding. good to know. in a three phase wiring distribution system (star connection i.e. 3 phase, 4 wire system); line to line voltage = 415v ac (208v in us) line to neutral voltage = 230v (120v in us) i.e.
