Calculating Breaker Register Numbers

Table 7 shows the sample register numbers for Breaker #1. There can
be many breakers in a panel. Determine the corresponding register

Breaker register # = Breaker #1 register + ((Breaker # – 1) x 200))
For example:
Breaker #2 starts at 1200:
Breaker #3 starts at 1400:
Breaker #14 starts at 3600:
This formula works for any register. For example, for Breaker #1, the
register number of "Watts Phase A" is 1055. The corresponding
address for Breaker #18 is:
