B. Machinery and equipment used to facilitate the production of voltage up to and including 34,500 volts shall be considered part of a distribution system.

1. Gross receipts from the sale of such equipment are subject to transaction privilege tax.

2. If tangible personal property was purchased as exempt, subsequent nonexempt use shall subject the gross purchase price to use tax according to statutory provisions.

C. Machinery and equipment used to facilitate the production of voltage above 34,500 volts shall be categorized as part of a transmission or distribution system based on the following definitions.

b. All land, structures, lines, switching and conversion stations, high tension apparatus and their control and protective equipment between a generating or receiving point and the entrance to a distribution center or wholesale point; and

c. All lines and equipment whose primary purpose is to augment, integrate, or tie together the sources of power supply.

2. "Distribution system" means all land, structures, conversion equipment, lines, line transformers, and other facilities employed between the primary source of supply and of delivery to customers, which are not includible in a transmission system whether or not such land, structures, and facilities are operated as part of a transmission system or as part of a distribution system.

The conductors shall be classified as transmission or distribution facilities according to the purpose for which they are used.

c. Based on statutory provisions, transformers and control equipment utilized operationally at transmission substation sites are considered to be a part of a transmission system and, therefore, are exempt from transaction privilege and use tax.

D. Machinery, equipment, or transmission lines for direct use in a transmission system are only those which are recorded as being part of a transmission system in accordance with the definitions in subsection (C).

1. Gross receipts from the sale of such equipment are exempt from the tax.
