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.
