STEP 9. Identify A-Row and B-Row Breakers
NOTE:
For purposes of Lumin installation, the top row of breakers will
always
be classified as “A”. The
second row of standard breakers will be “B”. The alternating A
-B-A-B pattern continues down the rows
of breakers.
Exception:
All breaker rows are designated “A”
in panels with two-wire single-phase power
rather than three-wire single-phase (split phase).
NOTE:
If the electrical panel
contains tandem or “skinny” breakers, there will be two breakers in a
standard breaker space. Thus, the top-to-bottom breaker panel will be A-A-B-B-A-A-B-B.
