You're talking about an Edison end box, yes in NYC but in other areas it's a no go. If they do allow it then like an Efison End box it needs a seal or 2. I seen multi meters on houses on LI and seems at least PSEGli is ok with them and don't even seal them. But I thought the OPs service was But 1 meter underground fed, and since there's no actual reason for a box or trough other than the contra tors self imposed hardship of running a business without the necessary tools, the utility will squash the "offset box" idea like a bug.It is after the meter. Plus here we install troughs on both sides of the meter depending on the application. NYC requires a service end box. or example #1. Three meters with one service feeder. Conduit with service feeders to a trough then down to three meters. or #2 a 400 amp Trans S to a trough to 2 - 200 amp panels. I have done both many times. Is this prohibited in other areas?
