Service Entrance Conductors

[Kissi Asiedu]

I have paid an electrician to wire my house in Ghana, Africa. The system
there is 220-240Volts to ground at 50 Hz. He is telling me he will use THHN
16mm2 (#6 AWG) for the service entrance conductors. Its a 3 phase system at
200amp load center (main breaker). Is the wire size right for this system? I
read NEC 2002 and it requires at least 2/0 copper for 200amp service. Any
suggestions please?

You are correct. Even that includes the "diversity" that one expects
in a residence. For a non-dwelling installation you would need 3/0

I have no clue if Ghana is as hot as Phoenix. We are required to install
4/0 copper for service entrance cables or 250 mcm AL. Check the temp derate
chart below the table.

Ghana may not have a electric code nor any enforcement. Check other homes
in the area and see what they installed. Sure is a lot of power for a
residence.

In th UK, a 230V system, I would use a 95sqmm conductor for the phases.
