Active = 1 Phase (240vac 50hz wrt Neutral) Neutral = "cold" side of all 3 phases Earth = Ground. (tied to a stake driven into the ground at the customers site) I don't know what happens at the generator end. Normally domestic stuff is either 2 pin polarised plug (all our Mains plugs have angled flat pins, they can't be inserted the wrong way) ie active/neutral only, Double insulated, or 3 pin polarised, with chassis grounded. Fuse is invariably on the active side. Some tv's I have worked on are "hot" chassis which effectively gives around 1/2 mains voltage between chassis and ground. Not unsafe for the customer as the controls and antenna connectors etc are capacitor isolated, but can be a trap for techs if you don't have an isolating transformer handy. Cheers Geoff
