Is there a regs compliant way to power a wifi mesh unit from the lighting circuit? The devices have a plug in adapter so it would involve a socket rather than wiring it in like a bathroom extractor, does that make it break the rules?
The connections would ideally be hidden in the ceiling space
+1 Trolling is not welcome.Ignore Winston's opinion.
I can't see that there is anything particularly unique about WiFi adaptors.The only problem using the wifi adaptors is same if lighting or power, the RCD must be suitable, I think for high frequancy it needs to be type F?
Am I the only person who feels that many of these recent discussions about types of RCD are a bit OTT?
I would imagine that it's very likley that the PSU of this device will be Class II
in which case RCD protection of it would be of very limited value, if any.
I'm glad that I'm not alone. To be fair, it's really only one person who keeps raising this 'RCD type' issue.No you are not.......
Exactly.Quite probably, no Earth connection. just Live and Neutral so no route for the earth leakage current necessary to trip an RCD
Even then, certainly in the OP's case, I don't think that the RCD protection would be particularly useful. With no local connection to earth, there would be no opportunity for a leakage to earth to arise within the SELV circuitry and, since we're talking about something which would very rarely be touched (and, it sounds, quite possibly not even accessible) at any time (let alone when 'in meltdown') by someone whose body provided a path to earth - not to mention the fact that all of the SELV circuitry would probably be within an insulated enclosure and hence not even 'touchable'.... RCD protection would only be any use if the PSU went into meltdown, destroyed or bypassed it's internal isolation and thus connected it's SELV output to the incoming mains. If that happened then the previously SELV wiring would need RCD protection.

Eric's concern appeared to be about 'high frequency' components, rather than DC components.I think the suggested problem is that the power supply will take a DC component from the mains which could affect the RCD which is protecting other things.
the use of type AC ones would surely be 'banned', at least on sockets circuits?
I know but, far from being banned, they are (or, at least, have been) close to being universal in UK domestic installations.They are banned in Germany, and not liked in France.
