[edit] 3-Phase houses in Europe?
In Europe, are houses actually wired with three-phase power? Given the additional copper or aluminium needed in the distribution circuits and service drops and the more-expensive panelboards required, combined with the limited utility of three-phase power in a residential setting, this seems like a tremendous waste to me.

- Every house and every flat in Sweden has three-phase power which is split out at the distribution board (panelboard). Normal outlets are 1-phase (230 V), but high load appliances such as stoves, water heaters, pumps, tumble dryers have 3-phase power (400 V). I think this goes for most of mainland Europe and I don't believe this is more wasteful than split-phase systems, probably less. It is disadvantageous in X10 installations, though.

- Wow! You lucky guys! Can I move to Switzerland? This would surely have made the installation of my air compressor better! (Then again, so would inherent 230 VAC, rather than our 120 VAC.) Well, there are a lot of good reasons to move to Switzerland, but that adds one more. ;-)

[edit] Photos
I've uploaded a bunch of photos per 84.12.176.217's request.

[edit] Powerline protocol physical-layer details
What does the term "0-o" mean? -- Beland 14:50, 18 July 2006 (UTC)
- Many edits ago, it used to almost say 0°, but not quite, and that not-quite-correct character apparently got "fixed" into "-o". I'll fix the article now -- thanks for calling it to folks' attention!

[edit] American RF frequency
I thought that the frequency in the U.S. was 315 MHz, not 310 MHz. Any comments?

- Someone check the FCC database of registered devices...
- Atlant 03:15, 6 January 2007 (UTC)
- Well, the FCC has searching of their data base turned off for "security" reasons, but there are enough breadcrumbs and Google caches left around to strongly suggest that 310 MHz is the correct value for America.

[edit] Power drain
Does an X-10 module draw power when idle? Particularly, does it consume any power when the device plugged into it is off? — Epastore 02:11, 8 May 2007 (UTC)
- Yes, the receiver portion of each module is certainly powered at all times. But the modules don't get very warm and the power conversion circuitry is pretty puny so I think the power consumption is probably a watt or so.

- I found this web page where somebody had measured several X-10 modules with a Kill a Watt. http://davehouston.net/x10-power.htm Also found this discussion, http://www.techmall.com/topic.asp?TOPIC_ID=1082 SwitchLinc V2 dimmer 0.06A, 1W, 8VA. Which suggests that the power factors of these modules may be fairly low, and that modules from different makers may vary significantly in efficiency draws.
