so over feeling sorry for customers

Last I noticed multiplugs were supplied with 0.75mm cables?

Would depend on the multiplug but they don't fall under the 0142 regs, if they're SABS approved they're not a problem as long as they're not fixed installation.

light fittings are'nt rated 10,15,20 amps.i doesnt have to be.you can use any light fitting on a 10,15,20 amp circuit . it is the cable that must be the correct size and protected.

25% + 16 amps = 20 amps
same for 32 amp socket outlets: 32 +25% = 40 amp c/breaker 6mm cable

This sequence begs the question that I suggest Sparks intended to imply - why the different handling of light fittings vs socket outlets when it comes to circuit over-current protection?

the way i see it is the light fitting can only use as much as the lamp wattage and the socket outlet as much as the appliance that is plugged in.for example a welding machine would push the socket outlet to maximum.

My eyes are burning from the tears of laughter. I just knew this would be good. Just to stir it up a bit more: the COC ends at the terminals of the appliance, to wit, the terminals behind the socket outlet.

To stir it up even more - ever seen a kettle plugged into a light socket?

And what about a 5 amp socket outlet on a 20A plug circuit? Is that OK?

its called planning....putting 7 plug sockets on a 1 x 20 amp breaker in a kitchen is bad planning...but unfortunately the budget rules so the planning goes out the window with good planning of the more expensive qualified electrcian...then the slander starts as soon as the first problem arises... then the more expensive contractor is called back and expected to fix for less than the original quote..."so over feeling sorry for customers"

plugging in 4 x a/c unit to one plug circuit...which already feeds the dishwasher...tumble drier...washing machine...toaters...microwave...kettle...is actuallty just neglegance on the part of the customer not the a/c company...why you ask because the customer should contact a qualified person to verify the load on the circuits which the aircons will be plugged into...it shouldnt be the a/c comapnaies fault as they are not responsible for the electrical installtion if the unit is plugged in...however i do disagree with the connector block half way down the wall when the wire is short...but ones again it is not part of the electrical installtion and therefore not illegall..."so over feeling sorry for customers"...you take short cuts you pay the price.

ok sparks you got me there .you going to get us to rewire light fittings with 2,5mm soon.
dave for interests sake a 5 amp socket outlet can work on any size circuit as long as a 5 amp circuit breaker is used as a switch.cbi sells these tiny breakers with small lug terminals. same as a cooker unit isolator with a plug in it. i wont go into the use of 5 amp sockets on light circuits.that would be asking for trouble.
any more unlikely scenarios i can shoot down?
