DO’S & DONT’S OF EARTHING SYSTEM

 


DO’S  & DONT’S OF EARTHING SYSTEM

 






DO’S :

 

1. Do ensure that the electrode shall, as far as practicable, it is embedded below permanent moisture level

2. Do inspect earth electrode frequently.

3. Do ensure that every earth wire shall be of copper, galvanized iron or steel.

4. Do ensure good and reliable electrical connection between earthing leads and earth electrodes.

5. Do ensure that path of earth wire should as far as possible, be out of reach of any person.

6. Do consider all parameters while designing earth system referring the relevant standards.

7. Do ensure the size of earthing wire are proper and according to IS 3043 (Code of practice for earthing and IE rules)

8. Do ensure that all materials, fittings etc. used in earthing system shall confirm to IS specification.

9. Do ensure safety earthing while working on electrical installations and earthing are properly connected on equipments.

10. Do ensure that as far as possible all earth terminals should be visible.

 

 ELECTRICAL SAFETY - DO'S & DON'T


DONT’S

 

1. Don’t connect single pole switch or fuse in a neutral circuit. Always connect it in the live or phase wire circuit.

2. Don’t renew a blown fuse until you are satisfied as to the cause of its blowing and also as to the removal of the cause.

3. Don’t use copper or aluminum wire as substitute for fuse wire.

4. Don’t touch or tamper with any electrical gear or conductor unless you have made sure that it is dead and earthed . High Voltage apparatus may give shock or flashover without touching.

5. Don’t disconnect earthing connections or render ineffective the safety gadgets installed on mains and apparatus till you are at work.

6. Don’t expose your eyes to an electric arc. Painful injury may result even with short exposure.

7. Don’t take unnecessary risk with electricity. Low voltage under certain circumstances can be dangerous.

8. Don’t use paint, enamel and grease on the electrodes.

9. Don’t use neutral conductor as earth wire.

10. Don’t use water pipe line for earthing.
