Panel Screen
Branch Ckt Loading
You can display Branch Ckt Loading (Branch Circuit Loading) status if the option to measure
current at the distribution breakers is installed.
You can view data for each individual panel position on the distribution panel. To view status of a
panel position, select the range that includes the position:
The panel position numbers on the screen correspond to the numbers on the distribution panel. (Odd
numbers are on the left; even numbers are on the right.)
After you have selected the correct range, press the Up and Down arrow keys to scroll through the list
of breakers in the selected range. Poles that are tied together will be shown on the same screen.
In the example above, the screen shows the third breaker of 21 breakers in the selected range. This is
a single-pole breaker, occupying panel position 05. The breaker is rated at 20 amps. The following
data are displayed for each pole:
• Irms: Measured root mean square (
RMS) current of the pole position.
• %LD: Present load as a percentage of rated load of the panel position.
Branch Ckt Limits
Available only if the option to measure individual currents is installed, Branch Ckt Limits (Branch
Circuit Limits) accesses a scrollable list of the breakers in the panel. For each breaker, the screen
displays, in the Loading column, the current on each panel position as a percentage of the rated
current. In the Load Alarm column, you can configure the high and low thresholds for the breaker as
a percentage of its rated current. For example, if you set 80% as the high threshold for a single-pole
20-amp breaker, an alarm condition occurs if the current reaches 16 amps.
