Q. State the general Do’s and Don’ts for working on electrical equipment.
Do’s :
1. Before replacing a lamp or handling a fan make sure that the supply is switched OFF.
2. Use correct size and quality of fuse wire while renewing blown fuse.
3. While removing fuse, pull out the supply end first and when replacing the fuse, supply end should be made ‘ON’ after this.
4. Place sign board “Men Working” or other warning boards on main switch before commencing the work
5. Before working on any circuit or apparatus, make sure that the controlling switches are opened and locked or the fuse withdrawn from holder.
Dont’s :
1. Do not connect single pole switch or fuse in a neutral circuit but always connect in the live or phase wire.
2. Do not renew a blown fuse until you are satisfied as to the cause and have rectified any iregularity.
3. Do not use copper wire as a substitute of fuse wire.
4. Do not close any switch, unless you are familiar with the circuit which it controls and know the reason for its being opened.
5. Do not touch or hamper with any electrical wire, conductors unless you are sure that it is dead and earthed. High voltage apparatus may give leakage shock or flash over even without touching.
