I do service work for a group of condo's, and the manager is asking that I write a letter to their insurance company, reassuring them that the existing wiring is safe and up to code. The service conductors ran to the sub-panels in each unit is of Al wire. The only other Al wiring in each unit is to the water heater #10, 240 volt and to the stove #6 240 volt. I'm trying to find the code section that allows the use of Al for services and also the section that allows the service, servicing the stove and water heater to be Al as well. I would appreciate the help... I have looked up all I can trying to find the section but have found nothing that specifies what I am looking for.
thanks for your help.... Rob
