There is only one lighting circuit

Apparently all new homes are suppose to have half the lights on one RCD

And the other half on another RCD

He is bringing a copy of the regs. to work tomorrow and show me

It's not unsafe, just not right

Don't have a wiring rules on me an haven't looked at one in a long time but if I remember light are considered 0.5A when calculating the load for a circuit. So 10A CB would be around 20 lighting points.

Something a lot of sparky's do these days when building new houses is only install a single 413 plug in the roof because of owners wanting to put there own down lights in which is easy for the sparky there max demand and circuit loading works out less because they only have to count it as 1 point. Then later the owner go to put there down light in and daisy chain more 413 outlet off the first and fit extra lights everywhere.

Edit: extraction fans and ceiling fans are also lighting points.

He said it's something to do with if you blow a circuit at night it's so you still half of your roof lights working...

He said when his house was built, they did the same... Made them come out and fix it because he had a copy of the wiring rules to prove it

I'll put a copy up when he gives it to me

Interesting, better check our fuse box.

[Lennox]

I thought that was just a best practise thing not a standard. 40A main switch seems a little small?

[discostig]

I checked ours and only see lights written on one fuse as well.

 

I know RCD is residual current device, that stops you dying if you stick a fork in the socket, and we have a power point at the water tank (Tank P-Pt), AC is obvious too.  HWS= hot water system, Oven...but what are the N1/2/3 and different "power" items?  

 

What does it all MEAN

 

[Lennox]

Secret sparky business mate [emoji14] nothing you need to worry about, n is just neutral. Just info for future sparkies. Power 1 etc is just numbers of separate power circuits.

[discostig]

That's exactly what I expected your illuminati overlords would tell you to say.

[Wilko16]

Yeah I got no idea to be honest, but if he can provide the info I will share it

Lol secret sparky buisness. The n1,n2n3 are just labelling of were the neutral of that circuit is terminated on the bar. Don't remember every seeing seperate lighting circuit being required but you may also have another set of rules on the east coast like we have here with our WA electrical requirements.
