This is probably a silly question but.. I have gotten some RGB strips 5050 5m each 60 LED per meter 30 LED per meter Using this 30amp 12v Power supply In the guide I see 4 core 14/020 security cable recommended with 4.5 amps capacity but would that actually handle my 60led per meter cable which is 1.2amp per meter for which I am guessing (.4amp per colour x5m) so 2amps per colour. Will doubling up be sufficient for this or do I need to go a larger cable, from what I gather the common return wire will be getting 6amps? Another option was get the 6core and use 3 for the return? Also for 10 meters of power cable when doubling up, should I solder both to the start of the run,1 on each end, or 1 on end and 1 in middle?
