I seem to have a different set of regulations to you , or my understanding of 6.16.3.3 is different .
SANS 10142-Ed3
6.16.3.3 Stove connection
6.16.3.3.1 A stove designed to be a free-standing appliance rated above 16 A
shall be connected through
a) a stove coupler which shall comply with SANS 60309-1 and of dimensions
as given in SANS 337 (a maximum of 45 A single-phase and 16 A per
phase for three phase), or
NOTE 1 Earth leakage protection is not required for the stove circuit when a stove
coupler is used.
NOTE 2 For a three-phase coupler, the earth connection needs special
consideration.
b) a socket-outlet that complies with SANS 60309-1 (industrial type) with
30 mA earth leakage protection, however, the use of industrial type socketoutlets
is not recommended for stove connections.
