More answers than he could ever want, thanks to cross-posted threads on at least two forums.

 

Received meter today. Will hook it up soon.

 

I have seen at least two, but it might be three, threads posting a similar question. One thread with a small meter with three leads.
Another thread asking about an AC watt-hour meter. And this thread, starting again about a low powered meter, but talking about a 26 amp kiln load. Also, a cheap DC meter does not work with a current transformer, it uses a shunt resistor.

 

Looks Ok?

 

I would put some sleeveing over the earth conductor, if that touches the live terminal things will go bang.

 

Given the close proximity of the mains terminals to the chassis, and the single insulation on the blue wires (voltage to the meter), I’d recommend you ensure a good earth connection to the metalwork.

Not bad advice. But I also see no need for it. Other opinions may vary.

 

The scheme shown in the photo of post #24 does contain what by some standards is a shock hazard. The small ires are wrapped around the large conductors and soldered, so that a bit of live conductor is exposed so that some fool could touch it.
I realize that the two diameters are very different, but still the normal method is to remove insulation from both conductors so that the wire and insulation can enter the insulating housing some small distance, and then with the clamping screw tightened the connection is secured.
The three wire terminal appears to be part of some device mounted on the other side of a panel, rather than a standard terminal strip.
Certainly that verifies that wiring it other wise would be much more difficult.
However, running one of the blue wires alongside the black mains feed wire, both through the current transformer, will totally cancel the portion of the load current drawn by the meter module, thus totally avoiding the effect on the measurement.
