Section 1
Phase Balancing
All three-phase meter stack modules come fac-
tory connected to phase A and B, per Figure A.
When connected to a 208Y/120 Vac 3-phase, 4-
wire system, field phase balancing of two out of
every three stacks is required. One of every
three stacks should be phased AC, per Figure B,
and one of every three stacks should be phased
CB, per Figure C.
Examples:
—9 Total Positions—use (3) 3-position stacks and
phase one per Figur
e B (A-C phasing) and one
per Figure C (C-B) phasing.
—16 Total Positions—use (2) 5-position and (2) 3-
position stacks. Phase balance (1) 5-position
per figure B (A-C phasing) and (1) 5-position
per Figure C (C-B phasing).
—19 Total Positions—where 4 position maximum
height is allowed by utility, use (1) 4-position
and (5) 3-position stacks. Phase balance (2) 3-
position stacks per Figure B (A-C phasing) and
(2) e-position stacks per Figure C (C-B) phasing.
