1. find load.... 8kw shower
2. find current Power/voltage ie. 8000/230 =34 amps
3. Use next fuse size up from current...40amp fuse/breaker
4. select a size cable suitable to carry 40amps
5. Find length of run. ie 20 meters.
6. carry out volt drop calculation
design current (34amps) x Length of run (20 meters) x
millivolt drop per meter (7.83 mvolts/meter for 4 square
cable) >>> 34 x 20 x 0.00783 = 5.44 volt drop!
if volt drop exceeds 9.2 volts use bigger cable
