I drew a scheme of the relay. Red dots are connector pins. Which two will the AC go through? Which two - DC? Also, my AC wire has a ground wire.. does that go to the middle pin?

Also, can someone verify if this will work:
Relay - (10A...
OK so the spiraled wire drawing pins attach to the AC power wire, the "switch" icon pins go to + and - DC (10A, 30V).. what about the middle pin? Is that ground? What do I connect that to?
Also, I would like to make it so my AC-wall outlet powered lights go on whenever I power on my PSU. How would I go about installing a relay? I found a cheap one on ebay...
Ok so instead of using tin/lead solder I would just wrap the wires around each other (like this: http://w6rec.com/duane/bmw/solder/solder12.jpg ) and then apply a soldering iron? Or would I just go ahead and heatshrink everything without applying heat?
I would assume that using scotchlocks is...
Thank you for the advice! I bought a DMM and spent the last week measuring everything I can find around the house with it.
I do have another question about my PSU setup though: I want to connect an external HDD to the PSU so that I can use its DC adapter to power other stuff.
Output for the...
I added a 3rd LED strip (this one is 5A) to the circut: http://www.bildites.lv/images/g2cj9ebs96n5j30xp9.jpg
Besides having to change the 2A fuse for a 5A fuse, do I have to add resistors or something or will this work fine?
Also, how would I measure the exact current produced by the PSU? I...
I updated the diagram: http://www.bildites.lv/images/jab1ge1ji7p9hrxa06lw.jpg
So pretty much that is safe to make, right? How would I go about to installing a dimmer? What specs do I look for when buying one for my circuit?
Here is what I don't understand though: so the PSU can supply 13 amps. The first LED strip would pull 2A. The second LED strip would also pull 2A. Wouldn't that cause 4A to flow through the fuse? That would surely blow the fuse! I only have 2A fuses lying around the house and even though I could...
Thanks for the quick reply!
Does this diagram look about right? http://www.bildites.lv/images/dmaqby8255rvro4judcz.jpg
Wouldn't the PSU blow out the 2A fuse if it is connected there? Where else would I put the fuse?
Also, DC- = ground. is that OK?
I have a 300W PSU that I use to power all kinds of small DC electronics around the house. I recently bought a strip of 12V LED lights. I tested the 4 pin peripheral with a multimeter and got 12.4V which is OK voltage-wise, however, the LED strip says "2A" on it and from what I know the PSU can...
