Domestic electrical installation is the assembly of associated electrical equipment supplied from a common point of origin to fulfill a specific purpose and having certain coordinated characteristics. Power cables must be correctly fitted with plugs and sockets. The cable should be as short as possible and should be unreeled before use. Power consumption is normally given in Watts or Kilowatts (1 Kilo watt = 1000 watts). If the total demand exceeds 3.3 Kilowatts (3300 watts) or 13 amps, then you will need a brand new circuit all the way from your main fuse board (consumer unit) in 6.00mm or 10.00mm cable to an area close to the cooker.
