Yeah...looks like it's best to measure my mains voltage at different times of the day and night.Trying to borrow a multimeter.

What makes voltage fluctuate? Why does it normally rise in the night time? Something to do with usage in ones neighbourhood? I usually have my stereo on between 11pm and 2.30am.

Thanks.

2. If equipment is made for 220V, it is also probably made for 60 Hz, not the 50 HZ used in Europe. Using 60 Hz equipment in a 50 Hz country is often a serious affair. The power transformer will have 20% less primary reactance and at best draw 20% more current. It may saturate - that makes for much heat and humming noise.

Actually single phase in the US has been 230 to 240V for a long time, ever since we left 110V legs behind. 😉 Single phase power distribution today is 240V center tapped for two 120V legs.
