open wiring

[ians]

they are on an equal par with porcelain connectors and insulated ferrules

Sorry dont agree with you if you are referring to a "skrewit". The helcon connector is by far a superior product. It is spring loaded which means it is always tight and if installed correctly and there are no live parts which can be accessed with the standard test finger and cannot be disconnected without the use of a tool. What i would like to do one day is do some tests with my thermal imager to see how they maintain connected to a 25 amp load.

i agree with sparks.no matter how good a quality helicon is, it will still be classed as exposed,and should be installed in a joint box.
i have seen a new product,a type of pvc round box that splits in half. you install it over the connections without disconnecting and reconnecting. it has a type of bush instead of the gland. i havent used it yet and not sure if its sabs approved,but it will make coc repairs a lot quicker.

Regs that exclude this type of wiring: The helacon is not SABS approved It was, but it has expired in 2011. It has NO IP RATING. Good solid regs i was looking for: (REGULATION 7.8.5.1 Joints in cables shall be avoided, however if required, they shall be made in an enclosure that affords a degree of protection not less than IP4X.)

And also Hellermann's reply:

"Ek het nou met Ken gepraat.

Ek het vir jou die RCC sertifikaat aangeheg, dis ongelukkig al wat ons beskikbaar het.

Hierdie connectors het nie n IP rating nie.

Die connections moet in junction boksies wees. (6.3.7.1 Joints and terminations of cables, cores and conductors shall be made in accordance with manufacturers' instructions or the appropriate part of SANS 10198.)

Laat weet asb as daar nog iets is waarmee ons kan help.

Dankie.
