With regards to Ians statement over the standard 3 phase socket in KFC - The clause covers that - it needs ELU.All the KFC and Hungry lions that we do have 3 phase ELU - We use the combined units and each socket has a ELU unit.


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
socket-outlets is not recommended for stove connections.
6.16.3.3.2 The stove connections shall be of hard wiring to the stove
terminals, by means of a flexible arrangement, which are mechanically
secured and be terminated on either end. When the stove is removed, the
hard wiring has to be removed.
Do you use a 30 mA ... 30 amp earth leakage with overcurrent protection ...4 mm wire and mount the sockets behind the chip/chicken frier?

I went back and checked projects completed ... 2014 was the last KFC we worked on ... wow ... 6 years ago ... time flies ... I am asuming they have revised the standard since then ... non of the KFC's we wired had earth leakage protection on any of the 3 phase sockets.

Do they still use those black tiles that you need to get a hilti diamond core drill to mount stuf ? We tried everything to drill holes in that black tile ... even tried a 500 ml water bottle with a small hole to cool the bit.
