killowatt Posted April 13, 2011 Report Share Posted April 13, 2011 I would like to run a 225A disconnect below a meter that would feed a main panel in house (225A main) and a panel (80A) in a seperate building. Can I double lug the disconnect to feed both of these? Link to comment Share on other sites More sharing options...
John Kogel Posted April 13, 2011 Report Share Posted April 13, 2011 You would not be permitted to do that here where I live, so that tells me it is not the best way. I think you should have a qualified electrician make that installation for you. He will make sure it is done safely and under the proper permits, so that it becomes an asset to your property instead of a repair item or a safety hazard. Doubling two conductors under one lug can result in a loose connection, heat, then fire. That is one reason it is not permitted. If you plan to run a smaller gauge feeder to the other location, it needs to be protected by an 80 amp breaker at the source. Otherwise, it could overheat and start a fire. The large main breaker doesn't protect it. The grounding of all three devices or panels has to be done correctly to prevent shock hazards. The safe way to get 80 amps to that other location is to run a correctly sized feeder from an 80 amp breaker in one of the other breaker panels.

Marc Posted April 13, 2011 Report Share Posted April 13, 2011 Louisiana uses the NEC. Your subpanel feeders will need to be protected with a breaker or fuse. Marc Link to comment Share on other sites More sharing options...
Tom Raymond Posted April 13, 2011 Report Share Posted April 13, 2011 Call a few electricians. When I upgraded the service at my house the electrician's price for the whole job was cheaper than I could buy the materials for. I saved money and got out of some work. That's a win win.
