Hi

I need help choosing the correct wire and circuit breaker, I am doing my office 100sqm with new 15 of 600x600 LED panels 38w each http://auroralighting.com/au/ProductDetail/AU-LP100CAK

They will be all on one circuit, the longest distance from the sub panel will be 20 meters.
What wire gauge and circuit breaker amp do I need?

I am thinking:
total watt 38 x 15 = 570watt
circuit amp 570 / 220v = 2.6amp
so a 5amp circuit breaker with a wire that more than 5 amp rating will do, like 18 gauge wire.

Am I thinking right?

Thank you

Use the standard: 1.5 sq mm phase and 2.5sq mm for null wire and 2.5 earth.
if you not running the wires in a pipe use 3x1.5 sq mm cable (stiff core) or 3x1 sq mm ( flex core).
fuse 10 amps or the std one 16 Amps.
