Is it normal to feel a very mild buzzing/tingling sensation from a metal
light switch plate? You can only feel it if you gently run a finger at right
angles to the 'grain' on the brushed metal surface. There's only one in the
house, so I can't compare it to any others. It all looks fine inside the
No. It suggests that the metal isn't earthed and a leakage path to live.
I expect it will also light one of those neon screwdrivers we are not
supposed to use any more due to strange elfin safety rulz.
Doesn't suggest that to me. If it was live, a static finger should feel
it, and there would not be a grain direction effect. Sounds to me like a
mechanical phenomenon. Easy check would be a DVM (on AC volts setting)
between the plate and an earth. Typical DVM impedance should be high
enough to show some voltage if the leakage current is enough to feel.
Sounds *exactly* like the effect noticed on Apple computers with
aluminium cases and non-earthed power supplies. If earthed, the tingling
disappears. So it seems very unlikely to be a mechanical phenomenon.
Some of the Apple power supplies are earthed when used with a cable but
not when plugged directly in. (Hmm, think it is that way round...) So
simply by using/not using the cable you can switch the tingle on and off.
Thanks, everyone. I'll get it checked.
Previous owner said the kitchen (including electrics) was fitted by Moben,
and seemed quite proud of it. A few things I've seen in there don't impress
me very much.
There just might be. The most annoying thing is the waste pipe under the
sink that goes upwards an inch or so before it goes outside. The hot/cold
plumbing under the sink seems unnecessarily complicated, too. It's like a
pile of trombones under there. There's a twin socket right under this lot,
too. I'm sure there should be something covering them, in case there's a
leak under the sink.
Kitchen fitters make shit electricians.
One bloody idiot was quite happy to have the dishwasher and w/machine
both plugged into a 4-way trailing outlet left under the kickboard.
Said 4-way was hard-wired into the back of a double socket. Ffs.
