I am running a long LED strip (24V, 21 meter, 0.6A per meter, so technically 13A).
The 24V PSU supplying power to the strips is to be connected to a switch that is rated 240V, 10A & 2400W.
1) Will that be a problem? 24V x 13A is technically 312 watts which is well within the rated watt. But the switch says 10A max.
Having said that, i understand that 10A calculation is based on the 240V voltage but i still want to be sure that this will not cause a problem.
2) The LED strips are in the same circuit as the LED ceiling lights which are also connected to the same switch.
It's usually the practice here to use 10A MCB for lighting circuit (1.5mm2 wire) but the 13A from the LED strips is already over this limit.
So do i separate the circuit for the LED ceiling lights from the LED strips circuit in order to use different breakers?
3) Does the max current for a wire remain the same for low voltage circuit? For instance, 1.5mm2 wire's max current for 240V is roughly 10-13A. Does that change when it is running 24V circuit instead?
For example, 10A x 240V = 2400W / 24V = 100A which means 1.5mm2 can safely power the led strip circuit that requires 13A?
I came into the above conclusion because 1.5mm2 = AWG#16 which has roughly 21A max current. 10A x 240V = 2400W / 110V = 21.8A.
Thanks in advance!
