4/0 4/0 2/0 Aluminum


Can I use 4/0 4/0 2/0 Aluminum wire from my meter to my service panel for a 200 amp service? It will be in 2 “conduit at a length of 50’

You have the correct size wire for a 200 amp service, but I need to wonder how you are going such a long distance from meter to panel.

A typical meter would be on the outside of the house just under or over the service drop or lateral. The main panel would be right near the meter, in the same enclosure as the meter, or just inside the house right where the service enterance conductors enter the house.

In order to run the service conductors a long distance between meter and main panel, the conductors must stay outside the home and enter at a point nearest the meter.

Its a new modular home. The sleeve in the basement is on the side of the house and they were to drop the service panel there, but instead they dropped it by the front door. I was going to run my conduit from the sleeve over to the panel inside. Does this sound ok? Also thanks for the help.

No. You cannot be that far into the house with the unfused service cable. You either need to have a main disconnect outside (or immediately inside), or run the service cable around the outside of the house to right where the main panel is.

Are you doing this yourself or having an electrician doing it?

15 feet?!? That is about the longest I have seen allowed.

Yes I'm doing it myself. I have a 200 amp disconnect, it is required if you can not go direct into the service panel

After the service disconnect, you will need 4 wires - hot, hot, neutral, ground.
If I am correct about what you are doing- meter to disconnect outside, from disconnect to inside of house to panel. The 4/0, 4/0, 2/0 will be OK from meter to disconnect, but not afterwards.
