Which power meters comply with a 4-wire + ground requirement?

Will appreciate your help on this. Thank you!

Is your question about the electrical network connection or about the meter communication port (old 4-wire RS485)?

This is about the electrical network connection.

[VictorMarincus · Accepted solution]

The meters which can be connected in a "5 wire system" (3 phase conductors, a neutral conductor and a separate ground conductor - the building ground) are the ones which have the GND terminal on their chassis (advanced metering and utility metering)- ION8xxx and ION7xxx.

This answers it. Thank you very much!

What about the PM8000?

Hi James,

The PM meters, in general, do not have exposed metallic parts therefore they do not require a grounding to protective earth (PE).
