SC II
SUPPLY CORD
Short
Middle (or low c.s.a)
Long
Notes:
The earth bond limit depends significantly on the supply cord length and its PE
wire cross-section.
SHORT should be set for appliances with a cord not longer than 5m.
MEDIUM can be used when the appliance supply cord is longer than 5m or the
cord wire has a small cross-section.
LONG can be used if the appliance has a very long supply cord (for instance
vacuum cleaners).
APPLIANCE FUSE
3 A (750 VA)
6 A (1.5 kVA)
10 A (2.5 kVA)
13 A (3.2 kVA)
Notes:
The earth bond test current depends on the set fuse rating of appliance. The
current is always at least 1.5 times higher than the fuse rating.
The power (in parenthesis) means the maximum power that can be delivered in
combination with the set fuse. Some users are more familiar with the nominal
power than the fuse rating.
Substitute leakage and leakage current limits (in heating and cooking) are set
according to the set power.
