3. TEP mails the applicant several items including:
   • TEP preliminary design for the electrical layout
   • TEP Service Requirements Specifications (SR Book)
   • An accompanying letter from TEP will ask the applicant to submit a legal description for easement to ensure that TEP employees have adequate space to perform any necessary work. The applicant may be required to have the property surveyed to satisfy this requirement.
   • If necessary, a TEP Designer or field technician will review plans.
4. The applicant must approve or request changes to TEP's preliminary design. Responses may be delivered via telephone, email, letter or fax.
5. A TEP designer will prepare a final construction drawing of the electrical system. A construction drawing containing SR Book references, a construction timeline and a letter are mailed to the applicant. A copy of drawing is mailed to other utilities (if applicable).
6. TEP sends an agreement to the applicant.
7. The applicant sign and notarizes easements, makes payments if required and executes any agreements.
8. Once TEP has received the easements and/or signed agreements, TEP will send "Approved for Construction" drawings and an accompanying letter to the applicant.

10. In situations where an applicant has installed a duct system, the applicant must call TEP and arrange for an inspection before backfilling the trench. Any concrete encased duct must be inspected prior to and after the pouring of concrete. After backfilling, a steel mandrel will be pulled through the duct in the presence of a field technician.
11. The applicant must frame the concrete transformer pad or purchase a pre-cast pad before called TEP for an inspection.

    • For three-phase systems, the applicant is responsible for pulling in own service conductors. The service point of delivery is typically at the secondary terminals in the transformer.
    • For single-phase systems, the applicant is responsible for installing a service trench and conduit. In these instances TEP will install the service conductors.
    • Once this work has been completed, the applicant should call TEP for a service inspection.

    • TEP passes service inspections for items that include meter sockets, connections, trenches, conduit and address labeling on panels.
    • Final clearance is received from the governmental agency.
    • All fees are paid and agreements are executed.
    • Once these requirements have been satisfied, TEP can connect service under the following guidelines:
    • For three-phase projects, TEP will tap customer's wire at the transformer and set meter on.
    • For single-phase projects, TEP will install service conductors and set meter on.
