| I'm a little bit baffled on this... whether or not it's allowed...
Original service is 100A - HVAC is currently a 90A breaker in that box...

| I believe that Article 230.71(A) of the NEC (2011) permits the arrangement you suggest. This Article provision is not new to the code by any means. If your inspector disagrees, this one is worth an appeal to his superior and higher if necessary. |

| To explain a bit more, in the plan you propose, the meter/load center is the service, the panels in the mobile home are then subpanels. Be sure to have the neutrals bonded only at the service, not in the subpanels. |
|
| The first disconnect is a main, and all panels after it are sub-panels. A main has a 3-wire feed (H-H-N) and a grounding electrode system. The main is the only place grounds and neutral may be connected. Subs require a four wire feed (H-H-N-G) and isolated grounds and neutrals in the sub-panels. |
