Breaker Panel Question?

Unregistered

I have a duplex and the breaker panel is inside a closet of a finished basement. The main breaker for the panel is out side the house next to the meter. Both sides of the duplex are like this. Woudl the panle in the closet be a sub planel

The reason for the Main breaker on the outside near the meter might have to do with the distance from where the sevice wire is feeding from the meter to where it is going to be breaker panel. There is a distance requirement that the breaker panel has to be within so many feet of the meter. If it isn't, then a main breaker has to be installed. It's a safety precaution. The only other reason I could think of is it could be somekind of local code required.

YES its a sub and its needs a 4 wire from dissconect to panel

Sounds like there is simply a "meter main" on the outside of the house, probably a 2 pack for both sides and one disconnect for each side?
If thats the case then your only panel is the one in the basement. I wouldnt call that a SUBpanel but is does require 4 wire to feed it. And I hope it isnt in a CLOTHES closet.
