Okay to short the COM's together and the +V's together? Would like to bundle them to drive the same load. Usually these single terminals are not rated for 20A.

I have 3 strips of LEDs(900 individual LEDs) and in total they take 17 amps. How are you getting 20 amps??There may be no need to double up at the terminals.

A multimeter shows the V+s are internally shorted as are the COM terminals, though I haven't tried running a 20A load through a single terminal or splitting it.

Trying to draw 100% of the rated load of a power supply is not a good idea. Especially with these cheap power supplies, I wouldn't go over 80%. According to Joseph's measurements, the terminals are off the same bus so depending on the design, shorting them wouldn't help anyway.

Yes you can, you have a common ground configuration just like my truck. Having the negative terminals tied together is common, and it will work fine.

NEC states only one wire per terminal, but the unit would work fine with 2, if you do not do it to code. It would have to be a very secure connection to avoid resistance heating. Try to do it to code if possible, extra breakers are only $15. Replacing some 15 and 20 amp single pole breakers with Tandem breakers in other slots would allow space to insert the extra breaker at the top of the lineup and keep it to code.

I don't see a problem with doing that. You could also just get 15 ports if you want to feed another 8 port unit from this one.

Actually, if you run 2 battery banks @12 volts, you would essentially be combining the two banks into 1. The terminals are tied together so positive/negative terminals on top and bottom are both the same terminal internally. You definitely need to use both terminals along with very large wire in order to provide the high amperage draw from the batteries. I hope this helps!

they sell 2 bank charges. you should get one of those. I dont think the three bank will perform well with one terminal dissconnected

Nothing on paper States. Lyman would have that info. However, I'm sure its low. I run two at the same time using the same plug with no issues.

It depends a lot on the application and duty cycle. If you're running a continuous load, 4 A should be perfectly safe. If you are running intermittent loads, I would not exceed 20 A, and only for short periods of time (feel the leads to see how quickly they warm up under higher loads). These are meant for testing and prototyping, so odds are you probably aren't walking away from the area... but if you are away from the area that these are being used, it's best to make sure the loads do not exceed 4 A continuous.

code says breaker should have one wire per terminal. It would work identically with the unit sharing a terminal, you decide.Use the one closest to the main input, usually the top most.

Yes. You should be able to add 1 more. But mine can only work with 2, because the middle port was bad.And it automatic detect which port is active and switch automatically.

Each terminal provides either 12, 13, 14, or 15 volts -- and yes, as long as you can squeeze the wires into the slots (or simply splice them together and send one wire to the box), it works fine for them to be joined. I have 3 sets of wires coming from different parts of the yard, all going to one of the terminals.

Yes, you can do that. Some people just buy a second small one in the future and combine the two with a special connector. That way works too but sometimes it can be a problem. I would go with the bigger.

I believe so. I intend to just that in the near future. The independent lines will go to the Load 1 and Load 2 terminals. You can also put each on a separate timer schedule.

NO! Don't put them in parallel. Because they are not identical, one will have a slightly higher output than another so it will attempt to supply more than its rated 100 Watts. Eventually it will fail. There's no way you can interconnect them to obtain equalized load.sharing.

The unit is well built. I'm running it as 30A per fuse with no troubles. If it were total that would be less than 5a per fuse which is pretty useless.

I don't think that can be answered. The specs don't include the frequency. I assume all would be the same, so no, you couldn't run two together. I'd suggest getting one of these and one of something else, but they might still be on the same frequency. Sorry, but I don't think anyone but the seller could help.

both are vertical for 15a applications, 20a will have one horizontal. a = amp
