Low Voltage Switchgear involves switches like power circuits, relays etc. It is important that a periodic inspection and test carried out at least every 1-2 years and 2-6 months when new equipment is installed. In this section we discuss about some guidelines for inspection and maintenance of low voltage switch gear 1)       On energized equipment                              Three things you must do a)       Listen for popping, spitting or cracking sound produced by the electrical discharges-also humming and vibrations produced by the resonance b)       Look for corona halos c)       Check for ozone – ozone is produced by corona or overheating of organic materials 2)       On de-energized equipment’s Three things you must do a)       Check and confirm that the equipment is free from physical damage b)       Check the foreign and loose hardware, distorted insulated bus and rusty or bent frameworks c)       Check the occurrence of carbon tracks, moisture stains, r

It is recommends that a periodic inspection and test of the electrical installation should be carried out by a registered electrician at least every five year. The electrical works should meets the national standards “You should never try to carry out your own electrical repairs” However, there are number of simple, visual checks that you can carry out yourself 1)       Check your RCD protection in your fuse-box 2)       Make sure that your plug sockets are not overloaded 3)       Ensure that plugs and sockets are not damaged 4)       Check that visible cables and leads are in good conditions 5)       Check that your light fittings are not visibly damaged and that down-lighters are in good working condition 6)       Check that you are not storing combustible materials around your fuse-box, electric meter or electrical ins-take 7)       Never trail cables under carpets or rugs 8)       Always switch off your electrical items when they are not in use

1)       Earthing electrode should be placed at least one and half meter  away from the building 2)       Earth wire should be same material with earth electrode 3)       The minimum sectional area of earth wire should be greater than 0.02 sq. inch and less than 0.1 sq. inch 4)       The size of earth conductor should not be less than half of the section of a line conductor 5)       The earth electrode should be taken as GI pipe with minimum diameter of 12 mm and at least 32 cm length 6)       Coal and salt mixture with loose soil should be filled around the earth electrode 7)       All the earth wire run along with the sub-circuits should be terminated hooked firmly at the main board 8)       The earth resistance should be low enough to flow of current sufficient to operate the protective relays and blow fuses

1)      Check the condition of your wiring. This should be done when you move into a new home and then once every 10 years.  It’s the lan dlord’s responsibility if you rent your home. Ask to see a copy of the certificate or report confirming that the electrics meet the standards (Requirements for Electrical Installations) 2) Check your sockets regularly. If you see burn marks or they feel hot, get a registered electrician to check them. 3) Turn off any electrical equipment you are not using. This especially important at night, there is a chance of fire that can spread quickly while you sleep. 4) Regularly check flexible cables on your appliances. Look for signs of fraying, general wear and tear, or a loose plug on kettles on similar appliances. Do this before you plug anything in. 5) Careful when using hand-held electrical equipment. Make sure you switch off and unplug this equipment when you have finished with it. This is important with items that get hot, such as hairdryer
