Steve: I don't get your point. There are 4 mains, with 4 meters, feeding four (4) spaces. That provides a disco for each of the 4 panels, within the 4 spaces.
This is a common set-up in strip malls, providing they conform to six (6) switches or less. Redsy was concerned with a 'main' in the tenant panel, so only one movement of the hand would shut down the space.
