How do I change the working distance in my Arc Flash spreadsheet?
|Working Distance||Equipment Type||kV|
|24 inches (610mm)||Switchgear||≤ 1|
|18 inches (455mm)||Panel||≤ 1|
|36 inches (910mm)||Switchgear||> 1 & < 35|
|72 inches (1829mm)||Switchgear||> 35|
|18 inches (455mm)||all others||N/A|
To change the working distanced based on your engineering judgment, left-click on the desired bus name cell and then right click to display the menu. Here you can 'unlink' six different fields.
This will unlink the working distance for a bus(s) you have selected, not all buses.
To globally change the working distances for several buses, highlight the working distance cells in the Arc Flash Evaluation window. Right-click to display the menu and select Global Change.
You may now enter a new value for the working distance. This can only be done for cells that have already been unlinked.
