A meter stack wherein each single phase meter base in the meter stack can be selectively connected in the field to any one of the A-B, A-C or B-C phase combinations of the vertical three phase bus bars in the meter stack by moving only the meter base line connectors. The vertical bus bars of the meter stack lie in a common plane and are equally spaced apart from one another. The vertical center line of each meter base in the meter stack coincides with the center line of the center vertical bus bar of the meter stack. Each of the two line side terminals of each meter base is associated with one of the outside vertical bus bars, and is located approximately half way between it's associated outside vertical bus bar and the center bus bar. A generally 'Z' shaped line connector attached to each of the line terminals can be easily rotated between its associated outside bus bar and the center bus bar, thus easily allowing a change in the A-B, A-C or B-C phase combinations of each meter base.
