This is not utility infrastructure. It’s a submeter connected to a set of current transformers.
In general in the US, for commercial buildings, everything beyond the utility transformer secondary is the responsibility of the customer. For a residence, anything beyond the meter socket is the responsibility of the customer.
I’m unfamiliar with UK utility standards though so perhaps it’s different there.
- b112 3y agoWeird. You have a meter, after the utility's meter, that you can just plug into?
- kabes 3y agoAt least in the netherlands and belgium, the meter is from the utility company, but comes with a public serial port (the so called P1 port) to read the data for smart home purposes.
- quickthrowman 3y agoNot by default, but tenant submeters are something you can install in your own premises wiring. Here’s an example, a single-phase meter made by Honeywell: https://prod-edam.honeywell.com/content/dam/honeywell-edam/hbt/en-us/documents/manuals-and-guides/installation-guides/hbt-bms-E-Mon-Class-1000-Meter-Installation-Instructions-62-0388.pdf?download=false https://prod-edam.honeywell.com/content/dam/honeywell-edam/h... The linked example only monitors one circuit, but you could buy a submeter than can monitor multiple current transformers/multiple circuits. The utility meter is supplied by the utility and used to bill you, an optional submeter is just for your own monitoring and tracking of electrical use.
