5A plugs and plugtops

[Derlyn]

Reg 6.15.2.1 states that socket outlets rated at less than 16A shall not be used in an electrical installation.

Does that include the 5A plugs that are made for conduit round boxes ?

[Dylboy]

But is it not mentioned in luninaires sections that we can use 5A? Not near reg now to look but just thinking there is. Could be a contradiction?

I find it best to read the complete clause - Unless otherwise allowed clears that one up and therefore Clause 6.14.1.4 and Clause 6.14.1.5 states 6 amp which means it is allow for in SANS 10142


6.15.2.1 Socket-outlets shall be rated in accordance with the intended load.
Unless otherwise allowed in this part of SANS 10142, socket-outlets rated at
less than 16 A shall not be used in an electrical installation.

What do you think about using a 5 amp unswitched plug for a small extractor in a bathroom?

Thanks

I just didn't want to go through the whole regulation book to see if there were any references to 5 Amp plugs.

I dont find any, only 6 Amp.

I note also that a 6 Amp plug can be used with a 20 Amp circuit breaker (6.14.1.5)

Can someone please describe what a partially dedicated socket outlet is. (6.14.1.5)

Final question. Those small 5 Amp plugs ...... What are they? 164-0, 164-1, 164-2, 164-3 Google doesn't want to help me.

At one stage it was not allowed , but changed in Ed 3 , I think.

It is now allowed as per 6.16.4.3 if switched with the lights.

6.16.4.3 Extraction fans
Where an extraction fan supply is switched with a luminaire, it shall be
connected to the switched portion of the light circuit, provided that the fan
circuit is connected by means of a SANS 164-3 or SANS 164-2-1 or
SANS 164-2-2 socket-outlet or a switch disconnector

Interesting, I have always called it a 5 amp plug. It seems even as far back as 2008, it was referred to as a 6 amp plug. I assume we are talking about he same thing?

Copied from an older version of the SANS regs.

"SANS 10142-1:2008
Edition 1.6
(As amended 2006 and 2008)
b) supplies one luminaire only, not exceeding the rating of the socketoutlet,
c) is accessible for maintenance purposes, and
d) is within 3 m of the luminaire that it supplies.
6.14.1.5 A lighting circuit that incorporates 6 A socket-outlets or 13 A socketoutlets
in accordance with 6.14.1.4 shall be protected by a circuit-breaker of
not exceeding 20 A. Lighting circuits that incorporate 13 A (fused plug top)
socket-outlets shall not be installed in a residential installation. Amdt 5"
