I don't know about the rest of my state (NY) but here in some towns and townships of Suffolk County there is a ban on Aluminum wiring. Some areas it seems that Al underground service feeders are ok and others it is not. In these areas we must put Adapters on the (even utility owned!) wires if we change the meterpan. We cannot use Al SEU cable for services for many years.
The Utility still continues to use Al as they have in the past.
