Wis. Admin. Code PSC § 113.0805

Wis. Admin. Code Public Service Commission § PSC 113.0805
See s. PSC 113.0808.
Care should be taken in determining the existence of diversion and amount of energy diverted. In case check-meters are used, the possibility of grounds between meters, normal meter inaccuracies and incorrect connections of meters should not be over-looked. The requirements of the Wisconsin state electrical code for entrances should effectively prevent such diversion. Attention is directed to ss. 939.32 and 943.20, Stats.
