Abstract: Disclosed herein is an apparatus for protecting against theft of electricity from a distribution transformer that transforms electricity from a higher distribution voltage to a lower secondary voltage. The distribution transformer is housed in a transformer housing having secondary terminals located thereon. The apparatus includes a protective enclosure attachable to the transformer housing so as to enclose the secondary terminals and a plurality of electricity meters for measuring electricity usage. The protective enclosure is configured to receive a plurality of secondary service lines. Each secondary service line is electrically connectable to one of the electricity meters. The apparatus also includes a secondary bus line located within the protective enclosure for electrically connecting the secondary terminals to the electricity meters.
