Two services metered two different ways, both with room to spare.
The suites don't share a meter. One buys power on its own utility meter from a 600 A feeder. The other is fed from the house system and settled by a submeter. Reading the switchboard, the panel directories and the transformer plates showed real headroom in both services on paper.
What we recommended
Build the combined load model from the field data, and settle the metering approach with the landlord early, because it shapes the whole one-line diagram.
