ECN Forum Forums General Topics of the Trade General Discussion Area 220, 230 or 240 volts, is it 110 or 120 volts?

Just wondering. When I measure the voltage in a panel across the line conductors I read 218 on my voltmeter. Is that a low reading on a 240 volt system or a high reading on a 120 - 208 system? From one leg to neutral I read 125 volts.
