Scruits

[GCE]

anyone manage to find the SANS regs for screwits ?

the ones which state they are SANS approved for the use in electrical installations ?

The wholsaler that sells them should be able to supply the certificate or at least get the certificate from the manufacturer that he buys from. Legally the wholesaler cant sell an item without a certificate

They all sell those GU10 Lamp holders without the earthed bracket and I'm still finding those chucked in with a connector block.....

The question of joints not in conduit boxes etc came up this morning and I decided to have a look at the regulations and dates

I have pasted Ed 3 clause on Joints below

I went back to SANS 10142-1, ED2 , ED 1.5 (2006) and ED 1 ( 2001) and the same basic clause is in all 3 books.

Joints as per manufacturers instructions

Looking at the Aberdare brochure it states under surfix and T&E - joints in boxes only ( pasted an extract below)

So I come to the conclusion that Twin & Earth/Surfix in ceiling spaces should be in round boxes at least and that the requirement has been out since at least 2001 if not earlier .I don't have an earlier edition to check against

6.3.7 Joints and terminations
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.
Flexible cables shall only be joined using termination boxes, cable couplers or
manufacturers’ jointing kits.
All joints shall be accessible, protected against strain, and protected in
accordance with 5.2.1, except for joints made and sealed permanently and
intended to be maintenance free.
6.3.7.2 Joints and terminations shall not
a) adversely affect the current-carrying capacity, the insulation resist-ance or
the earth continuity of the cable, core or conductor in which they are made,
b) be made in any connector, bend, elbow or tee-piece of a conduit,
c) allow the strands of a stranded conductor to spread, or
d) require strands of a stranded conductor to be cut away to allow connection
of the conductors (for example, to terminals).
