### For 100kw which cable size is good and how to find out cable size?

100 kw is the power drawn by the load. to calculate the cable
size you need to know the voltage. From that you can calculate the
current. this decides the cable size. for example if the voltage is
400Volts then the current flowing in the circuit when the load is
100 KW will be 250 amps. (100,000/400). for 250 amps to flow with
out causing excessive heating of the cable the cross sectional area
of the copper cable should be 150 sq mm.for a round cross section
the diameter will be roughly 15mm.

### How do you calculate cable size for 5kw load calculation?

Without knowing the nominal voltage, you cannot determine the
load current and, therefore, cannot determine the cable size.
<<>>
The sizing of cables or conductors is based on the amperage that
the conductor can safely carry. The formula for amperage is I =
W/E. Amps = 5000/Volts. With out a voltage stated an answer to this
question can not be answered. When you calculate the amperage,
re-ask your question for a conductor size for a given amperage.

### How to calculate the rating of the FUSE and Cable size. please tell the steps?

The calculations are worked backwards from the amps used by the
load of the circuit. This will be used to select the correct size
of the wire. Some stipulations are added depending of the ambient
temperature, length from the supply or if the load is a motor.
Fusing is then dependant on the wire size that is used.
