Example 2:
In

A
Device with eight sockets ; In
RDF = 0.6.
Eight sockets are to be used simultaneously.
Calculation of the total current In
InA = In
× RDF + ..... + In
C1
C8
In
= 8 × (16 A × 0.6)
A
InA = 76.8 A > InA = 63 A (device)
Difference = 13.8 A
9
In this case, all sockets may not be used simultaneously
as the load is 13.8 A above the maximum permitted
value of 63 A.
If the permitted rated current of the device is exceeded,
the number of sockets used must be reduced.
In this case only six sockets may be used because:
InA = 9.6 A × 6 (sockets) = 57.6 A (device)
In
= 57.6 A < InA = 63 A (device)

When using six sockets with an In
63 A of the device is not exceeded.

Taking the device out of service
f Disconnecting electrical consumers.
¨
Section 7.5.2 and Section 7.6.2
f Disconnect the device from the power supply.
¨
Section 7.4
f Wind up the connecting cable and place it on the
device.
Alternatively fasten the connecting cable to the device
with securing straps or cable ties.
