Cable Capacity Calculation Examples (reference examples)
The available cable sizes and characteristics vary with the territory and country and with the cabling
method.
The cable capacity calculation examples described below should be used as reference examples.
[1] For cables
①
and
②
connecting the circuit breakers on the switchboard, inverter(s) and looms, calcula-
tions are made on assumption of the voltage drop by supply voltage fluctuation as 5%, voltage drop by
cable
①
as 1% and voltage drop by cable
②
as 9%.
[2] The calculation for cable
②
between the inverter and the loom is an example when the inverter and loom
are directly connected.
[3] The calculation for cable
③
between the circuit breaker on the distribution board and the loom assumes
5% voltage drop due to supply voltage fluctuation and 5% voltage drop through cable
③
. (For other than
electronic shedding motion)
[4] In case of the electronic shedding motion, Refer to table [4] for the cable
③
between the distribution
board breaker and the loom.
