SAMPLE JUNCTION BOX / PANEL CODE
C A 3 – 05 – B2 A Wa N H – 0.5-150 – Z

NOTES

Note 1: Current control (Type “C”) panel types are only available in the Type “3” enclosure.
Note 2: If more than one main input terminal is required, indicate it in Column 5, as shown (i.e. B2, B3, etc.).
Note 3: For “Current Splitter” type panels, the Shunt Type, Monitoring, Adjustment Type and Adjustment Value codes are not applicable and should be marked as an “N”.
Note 4: For “Current Monitoring” type panels, the Adjustment Type and Adjustment Value codes are not applicable and should be marked as an “N”.
