So how is the volt meter wired to a 2-pole circuit? These tiny 18g wires will handle 40A?

The meter only reads voltage and current thru a shunt a DC shunt is a heavy buss and on the AC is a current transformer. The meter reads mv from the current transformer. That is the round thing with 2 wires coming out of it.

I soldered a short piece of #14 solid wire to the two voltage leads and covered with heat shrink tubing. Then I put these leads under the lugs of my sub-panel(feed from my generator) to read the incoming voltage from the generator.The meter comes with a coil which is placed around the circuit wire, this generates a very small current in the coil which the meter converts to the actual amperage, therefore the coil wire is carrying very little current. I hope this helps.

The "tiny wires are wired across the supply voltage to provide a voltage read-out as well as supply power to the meter.The meter comes with a small (app 1" dia) wire-wound toroid (doughnut) through which the actual load carrying wires (#8, #6, etc). are passed. The current carrying wire has a magnetic field around it, and that oscillating field induces an emf in the windings which are in turn connected to the meter.Not enough history at this time to say "yea' or "nay".

The load current does not flow through the 18ga wires. The toroid coil induces a small current in the 18ga wire (like a transformer). The small current is interpreted by the display electronics and will display 40.0 amps while there may only be .4 amps (or .040 amps) in the 18ga wires.

Wire the load as normal with its own circuit. Attache the volt meter to the line just as you would a multimeter black and red. The one lead to the load must pass through the amp meter transformer coil.

Unfortunately, your idea doesn't work as described on a 2-wire 220 circuit. That is, unless you use the bare ground as a neutral, and that isn't really too Kosher, although logically I don't know why. It would be nice to see what my submersible well pump, window mount A/C unit and air compressor are using.

I wouldn't. At the very least, I'd ask a licensed electrician. Plus, this device uses 14/2 wire (see the description), and I'm not sure it's safe to run 220 Volts with only two conductors.

not to hard to wire. the gnd is - of 12 volt supply you need to run this. next to the gnd is 1v that's the + 12 volt, goes they. all the other connections are the relays out , all have normal open and close contacts. #1 is nc, #2 is common , #3 no, I think, and so on #4 no, #5 c,# 6 no relay 2, hope that helps. o and better to use a power supply that some what reg, from 11- 14 volts. bob

No, there are 3 individual heating elements that require power to each. So 3 individual 40 amp double pole breakers are required needing 8 gauge wire.

As an electronics tech graduate, I can say with some certainty that the wire is low voltage. The wire is too small a gauge to handle 120 volts. Also these motion sensors only need low voltage to operate. Of course, the only way to know for certain would be to take the device apart and I'm sure I couldn't have returned it had I done so.

Hey Frank why do you feel you need to run a 220 line and breaker? The unit is set up for 110 plug and works jsut fine on that. I have a 2 ton unit and it is great on the 110.

Hi Joseph, what I found is that the 200A meter needs a few Amps before it starts registering, this is due to the high current range... This is assuming you have wired up correctly...

40 ma is a current, not a voltage. It does not measure current, but yes it can measure 40 mv. if you want to measure current, get a 1 ohm resistor add it to your circuit and measure the voltage across it and it will be equal to the current.

The amp meter needs the coil to have one lead of power fed thought it . Using AC I assum. Voltmeter one lead to ground and other to Hot side of AC.

sorry I'm not that savy with what your saying. Should I put a volt meter on the 2 lines and physically trip the sensor itself and look for a voltage spike or a contunity test doing the same thing?

Hello. I used mine for a 12V system. I am looking at one of mine that I haven't used yet right now.. there is no rating on it at all! Strange! The terminals on the end are not very big, like for a smaller gauge of wire that would be safe for a relay application but not large enough for 110 house wire. It's actually made pretty nice. So..I'm sorry that I am not much more help. Good luck

Hi,The unit I got is 240V, 20 Amps. Pretty easy to wire and so far has worked very well. It is a bit noisy but you get used to it.Rod

The hookup of the meter is very simple.2 green wires go to the pickup coil and the other 2 are for the AC voltage.Just put the high side of the lineTHRU THE sensor.Kc2igr1@gmail.com908.290.7622Mike

I'm not qualified to answer that question. I'm not a professional. I'm using it for lighting & a bath fan. I use a 15 amp breaker with 14g wire, not a 20. I always check manufactures recommendations. There may be local codes as well to consider when running a new circuit.

I used 18 ga wire and it's still 10x the size of the wire attached to the lights. With the minimum amp and voltage draw I did not use a relay. I simply wired directly to a 20 amp rocker switch.

After my last response I remembered how it was wired. You will need to read voltage at the battery. On the back of the meter is a plug with a 2 wire pigtail. The pig tail wires are red and black. The black wire goes to the negative post on the battery. The red wire goes to the positive post on the battery and the battery voltage will light up and you can read it all the time. The problem wiring it this way it is always on and can drain the battery of its voltage over time. The other way is wire the meter through an off and on switch. The black still goes to the negative battery terminal but you need to bring a red wire from the positive side of the switch and then on the wire coming out of the switch take that wire and connect it to the positive battery post. When you flip the switch off and on the meter will register. If you are not sure when the switch is on or off. A multimeter can be used. Set to ohms put one lead on one switch connector and the other lead on the other switch connector. One side will be able to read ohms and the other side will not as you flip the switch back and forth. The side that reads ohms goes to the positive terminal. Hope this all helps.
