Well, you could have 60Hz here if you care to run your own generator or converter-set. But then if you do that, you could have anything, anywhere!
These tables are notoriously unreliable, but this one looks worse than most.
Apparently Luxembourg has 110/220V service available for system-C receivers, but you can only run system-L sets on 3-phase! (Seems more likely that Luxembourg was a mix of 127/220 and 220/380 systems 20 yeas ago.)
I wonder why "Belgian" is tacked on the end of several entries?
