This should be correct because the current IEC 60446 standard is
neutral-blue, line-brown, and protective-earth-green/yellow.
There appears to be some kind of short white adapter between the
wall socket and the plug visible at time 41 seconds. Maybe that is
just part of the plug?
Look here:
http://de.wikipedia.org/wiki/Stecker-Typ_L
These plugs are symmetrical and blue-brown has no meaning, these can
be plugged in both orientations.
There is an 10A type and a 16 A type.
Best,

Wow, that is interesting. Thanks for posting that! The ground is the
center conductor, so neutral and line can be easily interchanged.
I dont suspect tricks with the power line. This is easily detected and
Matts Levan already used his own instrument during the test.
If the ground and neutral are shorted in the controller box then
plugging in an L-type plug gives one a 50-50 chance of sparks and
triggered circuit breaker. If they should happen to be shorted it in
the blue box would likely be intentional.
The above reference is for an L-type connector. I have appended a jpg
showing the wall connections. The plug on the left appears to be an
L-type. However, its cord runs up toward the ceiling. The cord on the
plug on the right leads to Rossi's power meter connection. It is not
clear to me that the receptacle on the right is an L-type. Its border
is different. Perhaps it is vertically aligned? The white adapter
might be to convert from a polarized 3 prong plug to an L-type. I have
a 120 V to 220 V EU converter box (useable vice versa) which has a
polarized receptacle for both voltages (differing configuration though),
and no L-type receptacle. The gray plug appears it might be a polarized
plug. I have no way to tell if the white thing is plugged into an
L-type receptacle. Maybe you are familiar with this kind of wall mount box?
I think this at the left side is a multinorm compatible Schuko.
The right plug in Rossis outlet is type L.
I dont know the purpose of the left cable. It is thin. Possibly it is
for the coffee machine ;-)
Look here, there are better images and english descriptions.:

"Schuko" is type F.
Im used to Schuko (type F). (Im in Germany) These are electrically
compatible but not mechanically. Schuko is non-polarized and I am used
to that.
Rossis wall outlet seems to be a combined Schuko - Type L outlet. This
makes sense, as they traditionally use Type L in Italy, but in new
installations they use Schuko, and so they probably have combined wall
outlets that support both standards.
There has also been some confusion about the voltage. Sometimes they say
220V and sometimes 230V.
This is easily explained: In earlier times some countries in europe used
220V and some used 240V. European union tries to harmonize the situation
and so, some years ago we went here in germany from 220 to 230V. But 220
V devices are still in use and they work. 220V is the old standard and
230V is the new standard, and normally thes are compatible.
I think, they have the same situation in Italy.

Peter
