Re: installing a fan... 4Dec 21, 2015 12:54 pm If you can't tell me what the following terms mean without Googling them, then you should stay the hell away from anything in excess of 48 volts. - Earth fault loop impedance - Earth continuity, and what value it needs to be? - Insulation resistance, and what value it needs to be? - Residual current earth leakage, what value it needs to be trip at and within what time frame? Coupled with the fact that what you have proposed will blow up your fan controller and possibly your fan as well, I think you should pay someone who has spent 4 years learning about what all of this stuff means and have some respect for what they have gone through and the licencing they need to maintain. Also think about the safety of your own family as well as anyone else who ever lives in your home in the future.

Seconded - also if you do this and it goes wrong after you've discussed it in a public forum you can wave your insurance bye bye Re: installing a fan... 6Dec 22, 2015 5:39 am I am an electrical engineer and employ the services of electrical contractors all the time, usually for large complicated projects, and have never had one charge more than $100/hr. Usually $60-95/hr + GST. Electrical work is regulated for good reason, and it is illegal to perform unlicensed electrical work in every state. That's because the majority of people who die from electrocution each year are either people performing unlicensed electrical work or as a result of incorrect installation by unlicensed persons. The biggest impediment to electrical safety comes in the form of those with displaced confidence who know enough to get themselves into trouble, but not enough to understand the consequences. In my experience it's usually those who are electronics or comms technicians, or someone who did a week's work experience with an electrician in high school, or someone who watched an electrician install something once, who think that just because they know where the red and black wires go, that they can do their own electrical work. Couldn't be further from the truth. It's easy enough to make something function, but to make it electrically safe is the job of a qualified and licenced electrician. My original points still stand.

Despite the fact I'm a chippy by trade with a lot of experience and could probably wire up a home from scratch, there is no way I would nor would I want to void my house insurance if something goes wrong. The old adage " A little bit of knowledge is dangerous " comes to mind. Stewie Re: installing a fan... 8Dec 22, 2015 10:17 am I've put up a few studs and noggings in my time too Stewie, but would never try and build a house either! I've also brazed a lot of copper pipes when I used to work with my old man in high school (he is a gasfitter/plumber) but I don't try my own plumbing work. Luckily for me I was and still am a qualified electrician prior to going to uni for engineering, but the engineers who I work with will still pay an electrician to do electrical work at their homes, which is probably a good thing because I've seen them try and use hand tools and it's not pretty. I think it was Socrates who said the definition of an educated man is one who understands the extent of his own ignorance. I think that's a good guideline to live by.

Of course the sparkys want you to use a sparky who will charge you anything from $100- $200 per hour. PM me and I'll tell you how to do it. And it's a licensed trade for a reason... I guessing from your arrogance you haven't bothered to complete the 4 years of tenure and then successfully pass the licensing exams. I hope when you're supplying information on how to do unlicensed electrical work you're also a big enough man to be liable and supply all your details so when (and it's a when and not if) it all goes wrong, the relevant electrical licensing body and locate you and prosecute you for supplying information on how to carry out unlicensed work. That's not to mention Worksafe Authority if someone gets hurt or the coroner if someone dies. I didn't bother chiming in earlier as I don't condone unlicensed electrical work by DIYers but I did look for and wish this forum had a report button to report the thread.
