Yeah like wreck says it might be polerised Live Neutral if it's a ground referenced neutral system you should read 240volts across live and earth and 0volts across neutral and earth. easy way to check for reversed wiring. Most installations in the UK only switch the Live so it's quite important its round the right way.

Here in the USA, for typical single phase house wiring, hot to the grounded (neutral) conductor will be 120v. Hot on one leg to hot on the other leg of the service line will be 240v. The 120v 2 prong plug are normally polarize. One stab on the plug will be larger than the other. Both 2 & 3 prong plugs connection screws are color coded. Green = ground. Brass = Black. Silver (white screw) = white.
