Please 'splain to an American what in the world a dwang is...as in your reply/post:

Now in an ideal world, we would take off the wall linings and drill new holes through the studs and dwangs, but I haven't met a house owner yet, who's willing to pay the extra. Or remove a roofing panel and drill down through the dwangs.

...as it is, I am not sure of your qualifying an ideal world that would allow such things in the walls of a human or even animal abode.

361857 2005-06-08 04:04:00 The construction of a wall in NZ consists of a top and bottom plate (usually 4" x 2" ) and vertical Studs holding them apart. To stop the studs bowing, "Dwangs" are placed between the studs. They are just horizontal 4x2 between studs.

I believe in the states they use plywood as bracing , over the whole frame, so wouldn't need those Dwangs.

A nice picture here (placemakers.co.nz)

361858 2005-06-08 04:09:00 Over here we call them "FIRE BLOCKS", and OK, you can have them with my permission in the walls over there...but please "dwangs" is kinda close to the sound a finger makes in a fan blade. :p SurferJoe46 (51)

361860 2005-06-08 05:01:00 I don't think it will be too much of a problem, except for the regulatory aspects .

I don't think you're allowed to have the data and power sockets in the same flush box (unless they are separated by a proper earthed partition . I'm pretty sure you mustn't clip the mains and data cables together (unless the data cable has insulation rated for 230V use) . There is probably a minmum spacing required .

50 Hz (or 100Hz) induced signals aren't going to bother the Ethernet (RF) signals at 10MHz and above . Switching transients, which might be a aproblem, are just that: transient . What's very bad is running Ethernet cables through fluorescent fittings . Fluorescent tubes are spark transmitters . :)

If you don't like the sound of the word dwang Joe, you can substitute the word nog or nogging which some in the less educated regions use .

Talking of running cables together, I was under a building the other week which had great masses of cat5 bundled together with 20mm entry mains, sub mains and tecoms cable draped over and around it (or visa versa) . While the contact is only fleeting, it's shear lazyness in both running the stuff and not separating the entry/exit points .
