Hi All,


Having just completely rewired an old state house, I wondering to hear from those who are using power-line adapters on different circuits, through circuit breakers and RCD's. Trying to find a definitive answer is proving really difficult.

They should work if you have a single fuse board (which I suspect you have).


BUT,  if your garage has a fuse board and your main house has a fuse board then powerlin adapter may not work between the two.






if rewired, how come no ethernet installed in key locations?

Cheers Goosey, yea Ethernet in but thinking of Powerline down the track into bedrooms that have no cat6,

I had it between a detached garage and house for a while. Really slow and only a few sockets in the house would link to the garage one. It seems that the units do not act as repeaters so ended up with weird things where things in some sockets in the house could see other things in the house, but not the garage and vice versa. Everyone says that RCDs block it, I dont know if they made it worse, but the biggest shift came from what else was plugged in. Putting a wemo switch in a 4 way powerstrip into the outlet adjacent to a powerline unit killed its thruput almost totally, putting a lamp did nothing, putting a PC also had severe effect but not as much as the wemo.


Initially it was on an extension cable that went to the garage because the wiring was never finished in it, that worked okayish, the other end of the extension went into the basement and up into the house where the other end of the powreline was plugged in to the same double outlet beside the extension. That only worked OK, so if its failing to deliver when the only thing it has to go thru is 30m of extenstion cable then expecting more from it with all the other house wiring in the way isnt really going to help much.


This was all with the 2 pack of dlink ones that you could redeem and get another 2 of the same with. There were faster ones available but the whole point was to pass some IP cameras between buildings and they were a big fail for that with frequent pixelation and random stutters in the feed.

If you have completely rewired a state house, why not put Cat6 cable in as well as power? If you have under-floor crawl space, you could still do this. Find a spot where you can mount a central data hub in a cabinet or something, and put in some form of patch panel for all the data cables running out to the bedrooms. If you're in Auckland, let me know if you need a hand to look at it and come up with a plan.

Almost every electronic device nowdays comes with RFI suppression circuits on it's mains input (except non compliant Chinese stuff of course). These circuits typically have at least 1 capacitor wired directly across the line and neutral terminals. And often there will be more wired Line - earth and earth - neutral. These capacitors are intended to behave as a short circuit at RF frequencies.


Example - random old computer PSU on my electronics bench has a 0.47uF capacitor across it's mains input. it's reactance is 6773ohm at 50Hz. At 20KHz, 16.9ohm. (far less and still in the audio frequency range) 50KHz - 6.7ohm. 320KHz - 1ohm. And at 1MHz - 0.33ohm. For all intents a short circuit at such frequency ranges.


That is just 1 power supply out of a house full of them. And if you have any magnetic ballasted fluro lights - They have power factor correction capacitors wired directly across the mains terminals. They are typically around 5-10uF. The frequency for 1ohm is now just 20KHz for an 8uF capacitor. Game over for any powerline signals. Any induction motors? Typically they will be capacitor start. Then the equivalent circuit is an inductor and a capacitor in series. At the resonant frequency - you get a short circuit. - More fun for power line signals.


Then there are light dimmers, solid state relays, and cheap motor speed controllers. All of which will either pump out lots of high frequency harmonics on the mains, Or will absorb other high frequencies - due to snubber circuits.


Just run more Ethernet cables. In alot of cases Im amazed that powerline networking is even able to work.
