Calculating Breaker Register Numbers
Table 7 shows the register numbers for Breaker #1. There can be many
breakers in a panel. Determine the corresponding register numbers for
other breakers in the panel by using the following formula:
Breaker register # = Breaker #1 re ((Breaker # – 1) x 200))
For example:
Breaker #2 starts at 1200:
1000 + ((2 – 1) x 200)
1000 + (1 x 200)
1000 + 200
1200
Breaker #3 starts at 1400:
1000 + ((3 – 1) x 200)
1000 + (2 x 200)
1000 + 400
1400
Breaker #14 starts at 3600:
1000 + ((14 – 1) x 200)
1000 + (13 x 200)
1000 + 2600
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:
1055 + ((18 – 1) x 200)
1055 + (17 x 200)
1055 + 3400
4455
