Hi all, Long time lurker first time poster here. I'm trying to get organised for next year with LED strips. I understand for the most part how everything works, but have a couple of questions around the actual connecting of the DC power supplies. First of all, are the negative terminals on the PSU already connected to ground? If not, is the best way to ground each output to have a jumper going from ground to negative? If this is the case, wouldn't the ground terminal end up getting pretty "full" with all the jumpers coming out? Secondly, when people mention injecting power into each strip, they're referring to running another lot of cables from separate terminals at the power supply to another point on the strips, yes? If true, this is why I'm assuming negative needs to have a jumper to ground on the power supply (strips have a 5V and GND connection, which I'm assuming is the positive and negative output from a power supply), so no extra pad just for ground. FINALLY, how do people tidy the connections coming out of the power supply? Are fork connectors the easiest way? I know there's a lot of questions here, so hopefully someone can help! Thanks!
