Selecting Conductor Materials
Like most utilities, we require the use of aluminum conductors for small- to medium-sized services. Aluminum is lighter, more flexible, and less expensive than copper. When you use aluminum conductors, costs are kept as low as possible by keeping our inventory of spare materials at a minimum. Properly installed aluminum conductors are safe and effective. Your overhead service riser is governed by the local inspection authority, not TID, and copper conductors are permitted and frequently used in this riser conduit.
For overhead service installations, TID will specify and install the conductors to your riser. For underground service installations, TID will specify the conductors you will install. Refer to the Customer Information Booklet for Installing Individual Underground Electric Facilities for information on acceptable conductors and a list of local electric supply companies.
