Roughing in electrics

[bio[diversity]]

I'm building a new, double brick house, which will be connected to a solar / wind / generator, 240 volt setup.

I will get an electrician to connect all the points and switches etc, and do the final checking of everything, but i'd like to run all the cables as i'm laying the bricks to make it easier and neater.

As i'll be running the cable through the brick wall cavity ( 50mm ) i'm wondering if...

A. I'm even allowed by law to do this at all, or does a licensed electrician have to do ALL the work.

B. If i can do it myself, do i have to run the flex through conduit, inside the cavity, and through any wall penetrations, or can it be run "bare" . It will most likely be touching, sitting on top of, the metal brick ties.

Any help with this would be appreciated muchly.

cheers,

You can do it legally, but only under the direct on-site supervision of a licensed electrician. You'll have to find one first that will let you do it. He'll then tell you what to do.

In any case, I would recommend you find a sparky first, because if you start pulling cables and he doesn't like what you've done - even if you get the best advice here - he's just as likely to either pull all your work down, or just walk away.

When you get your sparky to OK it (or not) make sure the cables are against the inside skin, and pulled tight. I was on a job once where there was a damp patch on the inside skin after a period of rain. After chopping the bricks out, it was found that the source was a slack cable in the cavity, conducting water from the outside skin to the inside skin.
Sparkies don't always get that one right themselves.

Speak to the licenced sparky first before you do anything else. They, if willing will specify cable type etc. If you do not, any sparky can bounce it or if the electrical inspector gets involved could end up very expensive for you in fines and rework.

Mate what ever you do get an expert in especially on a job like this where you are incorporating solar and wind generation it sounds as though you will require Transfer switches and the like have you had the electrical plans drawn up for this?

Just as everyone has said before you can only do it under direct supervision... make sure you find the sparky first because if you dont could end up with a heap of useless electrical cable in the wall and a big bill for somone to do it for you, regardless of how good a job you do... We can be a fickle bunch when it is our licence on the line.
