thetree13: So now the question is how does one go about boring a new hole?
I certainly don't have a drill bit of that diameter and if i did it wouldn't be 2 metres long.???

See the nominated topic answer, that just so happens to be the very first comment on your thread.

That is why there are extension bits. Sparkys pay a lot for tools like that which is why you should employ someone with the skills and tools to do a legal compliant job on the installation.

But watch out if you drill down the wall, there may be other services that you hit, ie power, water, sewage, gas.

Ever wondered why Sky installers refuse to do this type of thing, quite simply they are not allowed, as they either break the law as you have done or risk hitting unknown services.

You can get cameras that help with this,.

The TV coax whilst being ELV is not "Telecommunications". The separation of Faceplates would still be required but couldn't separation at other points be determined by cable insulation?

Hi, ELV is ELV as far as the law is concerned regardless of if its carrying Telco services or just local (ie antenna). Yes you can get cable that has a suitably voltage rated sheath, the pink cat5e used for c-bus applications is one such cable.

As mentioned earlier you could add a conduit to the coax to provide suitable seperation, you could also add a further suitably rated sleeve.

Honestly, at a guess, hiring a sparky will be cheaper (and result in a better outcome)

just chop the gib and patch. if you dont know what youre doing it will come out one side or the other meaning a worse thing to repair.

cyril7: Hi, in AU/NZ it is explicitly illegal to place an ELV and LV service on the same faceplate and hence flush box, this is coverd in PTC106 section 5.1.3, which inturn is referenced in AS/NZ3000-2007.

You can get flushboxs with appropriate faceplates that provide suitable separation, however they are not permitted for us in AU/NZ but are very common in the US.

Cyril

Yeah, thats why the clipsal 2000 and another similar system do the separate flush plate solution.

Im not sure if the dodgey installs I have seen with the extra mechs removed from a power point with extras was a dodgey sparky or a DIY job, but I hate the idea of all that exposed coax F connector (assuming its not a saddle back one) being that close to 230 in there.

US flushboxes are weird. You have to mount the normal NZ box behind the gib, not flush with it, so really they should be called behind-boxes or something, yet the US ones mount infront of the gib somewhat, so should be called stickout boxes. How they deal with the extra thickness sticking out when stopping is something I dont understand, must make it really really hard.

I remember at an open home I went to one time, seeing a PDL 600 series power point with an extra switch module. Someone had taken the switch module out and put a BT phone jack into it. *shakes head*

Have you seen the segeration boots that you can get from PDL for the BT phone jacks? It is quite possible that there was one fitted, but without removing the plate there is no way to tell

Hi grecmcc,
Yes, I have seen them. Even if there was one on the other side, there would have still be a phone wire right next to 230 volt mains cable. No idea if a sparky had installed that or some weekend cowboy.

Is there exception if the power is on an RCD? It would be stupid to put it on the same plate, but 2 plates and wires in close proximity should be okay if RCD'ed.

You can never have enough Volvos!

If the boot is in place then it meets the segeration requirments

richms: just chop the gib and patch. if you dont know what youre doing it will come out one side or the other meaning a worse thing to repair.

First off, I recommend you do what others have said, and get a sparky to do this work.

However, if you insist, or just want to pre-wire and get it certified and connected by a sparky (I assume that's legal? Can someone please confirm?) than removing patches of jib is by far the best option. I have done this several times, both for running speaker cables down from the ceiling (rear speakers) and for running cables up inside a wall for a TV. However both times they where well clear of power cables.

I generally remove a square or rectangle around the nogs, and again near studs (for face plates) then simply patch it up, fill the gaps, and repaint.

I have looked into the long drill bits plus extensions option, and for a DIY it's simply not worth it. You can get a small sheet of jib, filler, etc for less than $30.

Not as far as Telecom was concerned or the Telecommunications Carriers' Forum Code of Practice

"35.3. Under NO circumstances shall Low Voltage (LV e.g., 230 V) sockets, switches or
modules be mounted on the same faceplate as TNV or ELV components (voltage
levels at which telecommunications and data services operate). The joint
Australia/New Zealand Wiring Rules (AS/NZS 3000) require that all faceplates
comply with AS/NZS 3112, clause 3.2 of which prohibits mixing of these voltage
levels on the same faceplate. "
