Greece Power Grid

[SG-1]

I am looking at some equipment going to Thessaloniki, Greese. Everything ( lights, exhust fan, heaters, aisle heater ) is 240V.

What frequency is used 50 or 60 ?

Is one side of the 240V grounded or am I looking at Line to Line Voltage ? ( 120/240 Slash rated breakers are installed. )

We are providing two 3-way switches for the lights, one at each door. We are only breaking one side of the 240 volt circuit unless one side of the 240 is grounded. The switches are 20A Pass & Seymore with 208 120 277 stamped into them.

Any information is appreciated.

230v 50 hz

This is a nice site that shows the plug's attachment, states voltage and Freg.,

Here

Theres also a small boat load of various items across the top that deal with some of the end products..

Other sites say 220v 50 hz

As part of the EU it ought to be nominally 230V.
In reality it is 220V with a tolerance.
And it is 50Hz.

Greece is Europe so it'll be about 230V (as already noted), and that voltage is phase to neutral.

Thanks everyone for the help.

It's a bit unrelated so flag me if necessary... I may start working for a company soon that has international branches. I have a decent understanding of electrical code/applications in the US; where would some of you Euro fellows recommend is a good place to start learning about the European standards so that I may transition smoothly should an opportunity in Europe/European standard regions present itself?

As others post, Greece uses 50 cycles. Until recently the voltage was 220 volts, as part of European harmonisation this has been altered to 230 volts.

However I doubt that anyone altered the tappings on every grid transformer ! therefore the actual voltage supplied is still 220 most of the time in most places.

Larger premises normally have a 3 phase, 4 wire supply, with a grounded neutral at 230/400 volts nominal (but often 220/380 in practice)
Smaller premises would normally have a single phase 2 wire supply with grounded neutral at 230 volts nominal (but often 220 in practice)

In the past some supplies were 220 volt, 3 wire, 3 phase, without any neutral.
Others were 127/220 volt, 3 phase, 4 wire, with grounded neutral.
Both the above are now considered obsolete and non standard, but may still be encountered.
