What happens if two single electric meters are connected to two different loads with the same neutral (separated phases and combined neutral)?

What happens if two single electric meters are connected to two different loads with the same neutral (separated phases and combined neutral)?

Here is the conception drawing of the situation. When the neutral of two houses are same but different phases.

Energy Meter:

Energy meters are designed for domestic current ranges of few amperes (10–20) amps depending upon load requirements.

As per your  situation demands, let us understand consequences which will result.

Meter 2 will read its rated load consumption details and there will be no issue regarding meter 2.

Because local circuit for recording power details are met in load 2 circuit itself.

Coming to meter 1, here comes the actual consequence. Meter 1 reads its Load and Load of meter 2 also.

Meter 1 should damage due to large currents flowing in current coil, if current range of meter 1 exceeds. If not meter 1 should continuously read load 2 consumption also.

Current coil of meter 1 observe large current so, meter consumption increases though it is not actually consuming it.

So, consumer 1 should pay for 2 domestic loads, where consumer 2 wont have any issue and he pays for meter 2 only.
