Well.... seen this dragon once, had only one claw, but I needed a three claw one to fit in the door to open it, to finish my quest. Finally figured out that dragons feet come in different sizes and configurations, need the proper one, to open the doors!!

it cannot be done. even if you will take that voltage of 120 at three different output nothing will happen. you need three different phases to start the KWH meter. even if your KWH will measure something it will be the wrong measure. but... if you will find a way... good luck

lcalloway, Impossible at first glance, but here you will find there are ways to do the impossible.

You did not mention what type of test you are wanting to perform, but most meters are tested with single phase sources either way. On the back of the meter there are links that can be opened to separate the potential coils, giving you a wider range of connection options, but simply connecting both top clips to the same source line and the fifth clip to the other of the two lines (neutral if one of them is a neutral) and with the loads connected from each bottom clip through the load to the ending potential line that is on the fifth clip will produce accurate test results.

Greater detail from you will get more detailed answers in return from us. If you are using a phantom load device to produce the single phase current, you will have to use the links to separate the current from the potentials, and you can route the current through both elements of the meter.

Also if the meter is electronic, getting the display to light up is a consideration if only energizing a portion of the meter.

Accuracy test? Hi-pot test? Smoke test? (humor)
