Ring main + microgeneration

• The ring main is connected to the National Grid, transporting elec to all plug sockets in the house
• RIng main consists of 3 wires: live, neutral + earth
• 1. Ring main advantages:
  2. easier to add new plugs to separate wires
  3. Safer: we can hide so it's not cut
  4. Every plug socket = same V
• To add an extra socket, copy the lines
• MICROGENERATION = generating your own electricity
• Microgeneration = sustainable/renewable (helps Earth) + cheaper elec bills
• F.I.T (feed in tarrif) = price of unused microgeneration energy (solar panels) sold to National Grid
• Main ways of Microgeneration = - solar panels

  -Wind turbines

  sometimes called photovoltaic cells
• solar panels = microgeneration
• Wind turbines = Microgeneration
• Microgeneration = uses photovoltaic cells
• Advantage = wires can be thinner as there are two different current pathways
