Hello
I have an amp meter that I'm trying to connect to a baldor 220 volt single phase motor. The incoming power only has a black, red, and green wire; there is no neutral. The ant meter has two terminals on it and I assume the coil goes around the navy blue wire that leads to the motor. Any help is greatly appreciated.

 

Technically not the only option but probably the best in your case. (Best I can tell from your pictures). The same current flows through both the red and black source wires so your blue wire (solo wire connected to the red) should work.

 

Which wires would connect to the terminals on the meter itself?

 

I see now that is a meter with an led light. Not familiar with it. I looked up the meter on the internet but didnt see any thing that I would feel comfortable telling you what to do. It seems to be rated 60-380 VAC. I would assume you would apply your 230 v to them but I'm not sure. Good luck and be careful.

 

From the picture, it can be seen that it is a toroidal ring, so the measured current will be by induction.
It is enough to pass the electric wire through the ring.

Try a simple connection with electric bulbs of the different power.
The measured current should be within the limits of 10-100A.

Yes, I am looking for advice on which wires to connect to the 2 terminals on the led amp meter

 

Is this meter battery-powered?
It looks like the two terminals are for the sensing coil, if so, nothing else would connect there.
As has already been said, you need to route the wire with the current to be measured through the ring.
I like the suggestion, "Try a simple connection with electric bulbs of the different power." as this will be less dangerous and you can learn how to use the meter.

Hello,
It is not battery powered. It is powered by the two terminals at the bottom. I was going to try connecting both hot legs to it.

The coil attaches to the meter via a different connection

I would advise against that; I don't think there are many meters powered by 220 volts. What you really need is a manual or datasheet for the meter that will clarify how it is to be powered.

There is a possibility that it is powered by the sensed current itself.

You can try with a transformer with a low voltage (~10-12 VA) output and current of at least ~2A. you use a load with low impedance.
