Why are there two neutrals and a ground? On my 12v system the ground is only on the line voltage side. No ground to the 12v light track

Per the sticker on the side: red wires hook up the supply +12V and load (lamp/strip) +12V. It doesn't matter which you connect where, as they are bussed together at the switch. Black wire connects to supply GND, and green to the load's GND wire. This device operates as a low-side switch, so when switched off, the device will actually have a potential of +12V.

It is a negative ground. Of it wasn't any ways, you could reverse the wiring at the controller.

Ground is one, 20A is other, I got mine working with 12v power supply and ground, still haven't had time to supply separate 20A 12v supply to power led lighting

The three wire system utalizes 1-a power source = black feed wire which connects to the black wire on the cad cell.-- 2 -a grounded neutral =white wire which connects to the white wire on the cad cell.--3 - and the switched leg = red wire which is internally connected to the load side of the cad cell and is connected to the light fixture black wire. If you have a two wire system, its likely there is an established grounded neutral from another source and will need to use that as well for the cad cell to function.

Neutral and Line, at least that's how I interpreted it. When hooking up the power cord I went green wire to ground, white wire to N and black wire to L.

Despite the reply from Phoenix Down... ...many of these type of devices do work without a neutral (aka grounded wire). As explained in other replies to diff questions, the grounding wire, often bare or green (not to be confused with the grounded wire..aka neutral) is acceptable by UL (Underwriters Labs) and the NAC (National Electrical Code). To simplify my reply.... ....it seems it's perfectly acceptable not to have a neutral on this device but instead the ground wire (again, green or bare copper).

Hi Dach, the screen shows only the voltage. The are some LEDs in the front panel that shows if the ground is ok, protection ok, clean ok, etc.

I am not an electrician so what I would do is Google it. Check out this site... http://www.epanorama.net/documents/groundloop/why_grounding.html

You have to put them in parallel to maintain 12 volts in the system.all positive together all negative together.assuming you're inverter and charge controller is 12 volts

Hmm, that's a new one on me - is one of them a chassis ground? I would just figure out which the ground and neutral were and tie them together...

Okay, sorry. Amazon asked me to comment on this by saying "since you own this unit maybe you could answer the question" But evidently I don't own this unit, because the model I have has a ground post and 6 negative connections.. Sorry all.

You're probably thrown off because it had two sets of terminals. That's so you can run these in series. You can attach neutral to either one of the terminals of one pair and vice versa for hot, and it doesn't matter which one. So if you only have one wire, you have one empty terminal on each side.

The gauge has a warning label to be used with only a 12V - Ground system. I would check with the manufacturer before buying to confirm your application.

It's all on the hot wire -- this is A/C. It's like regular house current. If you test from the hot wire to the ground, you get the voltage. If you test from the hot wire to the neutral, you get the voltage, but if you test from neutral to ground, you get nothing.

I grounded the switch panel to the ground on my harness wire from the engine. All the attachments like lights and other items, those are grounded to a small bus bar that I then grounded to the neg batt terminal.

Yes. Now, arguably you can connect the neutral to the ground and it will still work -- but ideally this should be connected to a white neutral.

I believe this unit has no ground terminal but is hooked directly to the batteries which should have a negative ground. Since the panels are also grounded, it all should be fine.
