Duplex Houses

[wmeek]

If you were going to design a Service to feed a Duplex House, Can you use Table 310-15 (B)(6) for Service Entrance Conductor Size. Also if each unit will have a 125A Main Service, what size service entrance conductors would be required ( One Set to feed both units Via Gutter )

Thanks

Here ya go. Just ignore the meters if your not using them.

Utilizing table 310.15(B)(6), the conductors to each INDIVIDUAL 125 ampere dwelling unit panel would need to be #2 copper or 1/0 AL. The riser conductors (between the meter socket and the service point) would be sized per table 310.16 based on the calculated load of the entire building.

The last duplex I did I was allowed by the poco to drop a 150a for two 100 amp panels. Check with poco first
