The two input variables are:
N
-
number of ES 20s supplied through the cable
G
-
cable gauge in square millimeters
For 110-120 V models the following formula applies:
This means that the cable length is proportional to the cable gauge, while it is inversely
proportional to the number of ES 20s supplied through the cable.
On this and the next page, per mains voltage a table is shown with the maximum mains cable
length in meters, given the cable gauge in square millimeters and the number of ES 20s supplied
through the cable.
Maximum Length (ML) =
G * 15
N
Maximum Length (ML) =
