maybe in the wrong section but...

without opening the usual can of worms....

cabling: can an owner builder do their own cabling for the ducted vacuum???it is usually 24volt - just for the switches at the end of the openings where the vacumm hose plugs in( it means that the vacuum switches on when the hose is plugged in)??? its probably another AUSTRALIAN GREY AREA.....

If not - is it the electricians job or a cablers job....

Ducted vacuums can be installed by any handyperson. DIY are readily available.
The wiring from the pipework back to the unit is all 12 volt and safe
Yes the metal cuff on the end of the hose makes the unit work when you plug it into the inlet valve if you are using a standard hose
Switch hoses are also available they turn on the system when you flick the switch on the handle

so this brings back that well tried and trusted can of worms... if 12 volt is "safe" why can you not diy data?????I mean at the end of the day... you or someone else could just as easily put a steel implement (accidentaly)through the cable the same as you could with a data cable...blah blah blah.....

I don't know - maybe there are regulations that have to be met with those things - I just know there isn't any requirements other than perhaps commonsense with ducted vacuuming

Hi,

I think that the crucial difference is that the communications network extends outside your house (You may only intend to use your data cabling for an internal Ethernet but a future purchaser could put telephone services over the same cabling). This gives rise to two issues:

• What you do in your house can affect people/equipment outside it
• What happens to the network outside your house can affect you

Now personally, I believe that there should be some scope for some DIY cabling. In my opinion there is a huge gulf between the current restricted and open registration categories. In particular the restricted registration does not allow work where there is a 'jumperable distributor' - however if someone isn't capable of installing data cabling to a 24 port patch panel, I don't want them doing any wiring anyway . I believe that there is scope for a non-commercial "diy" class of registration that could be achieved through a TAFE course or other approved training provider with appropriate assessment of theory and practical competence.

For my house I obtained an open registration - the tax deductable $900 training course fee will save me thousands in cabling costs, but this isn't an option for everyone.

How did you go about gaining the required amount of practical experience without being in a professional cabling environment?

Hi,

With competency based assessment you do not need specific hours of experience - you are assessed by a registered training provider against the required competencies. Information on what is assessed can be found on the right side of this page.

Having said that, however, you are unlikely to be assessed competent if you have never terminated any cables prior to entering the exam room - There is nothing to stop you from buying tools, sockets, modules and cable from a wholesaler to train yourself. Just don't install it.

Simple. Data can be connected to the public network, so there is a risk to the equipment and personnel of the carriers if you happen to do it incorrectly.

but - what if you use cat 5 or cat 6 - which is data cable - to run for soemthing compleetley different....ie av to an in house projecotor or even for sound on a digital desk...??? can you do it with out a license?? I mean technically some idiot could try to plug a phone in it, but being as it is not connected to any phone network.. nothing is going to happen - so can we run cat 5 or 6 if it is not connected to a phone network...

why on earth wouldn't you run a HDMI/ VGA cable to a projector instead of a Cat5e/6 cable? (unless it is over 20m.) then and only then does using baluns help..

and you can run those yourself.. unless you have no common sense about installaing cables so they don't get trashed.

simnple facts why comms cabling Isn' DIY.

1) The entire comns industry is a protected Industry.. so DIY'ers don't stuff up the greater telecommunications Network..

2) if you have a Sturcture system installed (which most are) means you can send a PSTN signal anywhere with in that network. by simply patching it there.. so that means all cabling must be installed propply..

nothing is stopping you getting your Comms Licence.. for most of you that would mean a tafe course 1 day a week for two semesters plus the $900- $1200 fee (plus add the time off work to study a non work related [for most]) skill I'm sure you boss would understand.

Construction inudsty White card $100ish for a day course

then there is the registering with a register $80 odd for the first time then $33/ year for contiual rego after that.

Next Public Liabiltgy Insurence: about $800/ year.

futher upskilling : $250- $3,000/ year

I could go on but i think you get the idea..

yes it is a "club" of sorts.. and some of us have cool jackets..

Righto, I was under the impression that there was a non-negotiable real-world experience requirement. Similar to driving a car etc. In fact that's pretty much the only thing that's stopped me from going for my cabling ticket.

but you still need someone to sign off on your completting 600 hour sof supervised "training"

I see. It's all too complicated for my tiny brain.

the av I am talking about has a run longer than 20m and so balans would be used. so can I install it? the cat5 would be plugged in both ends to the baluns, and the one would go directly into the camera, and the other into the wall plate coming out on various video connectors (not cat5) so technically no one could plug telecomms into it?? this is not in my own house.

As i understand it, I can install cable but not telecomms or pay tv???so in my own house I can do coax, data (which is self contained within the house ) not going anywhere into telecomms etc... and speaker cabling and my own security system again if not connected to an outside system ( ie it doesnt dial up to an outside company).

I could do the course, but dont have the time for 600 hours of supervision.... having worked in the UK and currently working in the audio theatrical sphere, I do cabling regularly for temp runs etc etc... so even after talking to the licensing authorities the answers are as clear as mud....
