It goes without saying that it is dangerous for any one to work with electricity - you risk not only your own life but those living in the house - unless you are a trained and qualified electrician to the required knowledge level and thus, actually know what you are doing. It is also under the Part P Regulations, illegal! If you are not electrocuted you could be prosecuted!A trained and qualified electrician always recognsies when a DIY job has been previously carried out by a householder! The tell-tale signs always show!Below are some of the most common bodged electrical jobs, as reported by electricians when arriving to sort out a fault :Fuse Box Installation - An electrical box installed too far out of the wall.Wire Size - an added outlet or circuit too low rated.Fuse Replacement - fuse or breaker replaced with a larger - and wrong - size.Light Bulbs - higher wattage bulbs fitted above recommended limit. Danger of overheating and fire!Wire Connections in a Box - incorrect wire lengths when making a connection in a junction box.Loose Wire Connections - a stripped conductor and another wire wrapped around it to make a connection.Loose Connections in Panels - especially a loose neutral ( causes flickering - and overheating)Proper Wires Connected to Terminals - a wire connected to the wrong terminal !Overloading Outlets - use of multi-outlet circuit extenders . Appliances like dishwashers, refrigerators, freezers, washing machines, all draw a lot of power and need their own supply.Wire Straps - NM (Romex) wire straps nailed too tightly. Must be support ed securely to the wooden studs by nailing straps around the wire. This ensures the wire doesn't hang loosely in the wall channel and so the wire doesn't get pinched in the wall when drywall is installed.There are a variety of short electrical courses always available and over weekends for gaining certificated knowlege of basic electrics. For those who wish to find out more and go on to higher NVQ level training, there are approved and accredited City & Guilds courses, starting with 5 or 10 day units and extending into set courses of longer duration.
