Electrical Wiring and Testing
Drawings and technical information can be obtained from a maintenance company or on site services which undertake building maintenance. Only obtain original copies to be certain that they are correct. Storage is also important to garantee the care and safe keeping of the documents. Firstly they should be stored in a safe environment. They should be kept above water level in case of floodings. Copies of the documents should only be issued autherised personnel only. You could also ontain desighns and technical informtaion from architectual and engineering firms which could have master copies as they carry out the original design specification. ? Work activities need to be planned so you have a clear objective and overview of the job. Planning includes such things as: -Time : how long the job is estimated to take, hiring building equiment and materials.
Cost (budget) : how much money will be spent, including out of hours work. -Manpower : this is estimating the labour you need for the job. The manpower needs to comply with health and safety regulations. The methods used to produce a work plan are bar charts, which thoroughly explain thoroughly each stage of the work, grouped into time, materials, labour etc. A good work plan should include the estimated cost of the job, the estimated time divided into sections for each part of the job, labour (how many wotkers for how long) and also equipment which is needed for the work, considering hiring and the time periods. ? The electrical equipment and tools for wiring operations are: -Hacksaw, -pipe cutter, -file, -reamer, -bending equipment -bending machine. Equipment used for forming and installation operations are: -Stock and dies -pipe vice -pipe wrenches -busg spanner -screwdriver -side cutter -cable stand -electrical drill. ? The range of electrical components , cables and connectors used are: -Conduit -Traywork and trunking are available from manufacturers -pvc -Steel (black enamel), flexible -Galvanised -Ceiling rode -Connectors -Socket ? The factors which affect the selection of cables and components are: -Amount of circuits to be installed (size of installation) -Environmental influences (indoor or outdoor installation) -Proximity to other services eg. water and gas -Check the design specification to have an overview. -Cost of installation, correct or most suitable material for the circumstances. -Comply with IE Regulations. ? Some typical things that might go wrong with components, tools equipment or installation activities are that after a long period of usage the equipment might get damaged (this is what we call wear and tear) and they might need replacing. The equipment might also face mechanical failures due to extensive use. Improper installation might aslo have occured and components, which are damaged or being used in the wrong place or improperly. The components may be damaged or weathered and might need replacing. If the problems do occur then it?s the best course of action to report the damage to your supervisor to ensure the safety and well being of the rest of the workforce. ? It is important to maintain good housekeeping and equipment control to ensure the safety of the workforce and that equipment is maintained properly.It is important to safely store tools, equipment, materials so: -The equipment is in good working condition and prevents any damage or injury to other employees. -They don?t become obstacles and a hazard to you and the rest of the employees. To maintain good housekeeping control, you must: -Prevent accidents -Improve service -Return equipment in good condition -Secure stock ? You may use your initiative at work when there areminor problems and alterations which are easy to fix and don?t take too much time or additional use of extra equipment, and you keep inside your time plan then its advisable that you handle it yourself. If the problem is bound to cause you to lose a lot of working time trying to fix it then its advisable to seek help from your supervisor. It is also recommended that you seek help in cases where health and safety is concerned to make sure everyone is working in a safe environment.
