Indian Electricity Rules, 1956 

U/s 37 of the Electricity Act, 1910, the Central Electricity Board, made these rules which were published and came into force from 26-6-1956.

The rules were amended in 1991, 1993, 2000, 2002. It has 11 Chapters, 143 rules and 15 Annexure. From safety point of view following two chapters are more important.

Chapter Rules Title

IV 29-46 General Safety Requirements.

X 109-132 Additional Precautions to be adopted in Mines & Oil-fields.

A short summary of the rules is given below. For full details, the statute book should be referred.

Rule 2 gives 57 definitions. ‘Danger’ is defined as danger to life or body part from shock, bum, fire, explosion, injury to persons or property because of the electrical energy.

Flameproof enclosure means an enclosure for electrical machinery or apparatus to withstand internal explosion due to flammable gas or vapor entered inside and preventing this internal Flammation to come out to the external flammable gas or vapor in which it is designed to be used.

Guarded means covered, shielded, fenced or otherwise protected by means of suitable casing, barrier, rails or metal screens to remove the possibility of dangerous contact or approach by persons or object to a point of danger.

‘Intrinsically safe’ as applied to apparatus o associated circuits shall denote that any sparking that may occur in normal working is incapable to cause explosion of inflammable gas or vapor.

Voltage category is defined as low<250V medium<650V, high<33KV, extra high> 33KV.




Rule 4 prescribes appointment and qualification for Electrical Inspectors that degree in electrical engineering with at least 8 years practical experience For assistant inspectors BE(E) + 3 years experience o DME + 6 years experience is prescribed. Rule 5 give their powers of entry and inspection.

Chapter-3, rules 11 to 28 prescribes licensing procedure including maps, forms and conditions.

Chapter-4, rules 29 to 46, give following genera safety provisions General Safety Provisions:

  1. Electric supply lines and apparatus, shall be Sufficient ratings, mechanical strength and constructed, installed, protected, worked and maintained to ensure safety of human being, animals and property. IS and National Electrical Code shall be followed (R29).
  2. Supplier and consumer, both, will take due precautions to avoid danger from service lines and apparatus on consumer’s premises (R30).
  3. Suitable cut-outs (e.g. fuse) in fireproof receptacles shall be provided in every service line (other than earth lines) at consumer’s premises (R.31).
  4. Earth and neutral conductors shall be identified to distinguish from live conductor and position of switches and cut-out shall be safe (R32).
  5. Earth connection (terminal) shall be provided near the point of start of supply and the consumer shall take steps to protect it from mechanical damage (R33).
  6. Bare conductors should be inaccessible with readily accessible switches to cut off power supply (R34). 5
  7. Danger notice in Hindi, English or local language with a sign of skull and bones (IS-2551) and the words ‘danger’ and ‘volts’ is necessary near medium and higher voltage installation (i. e. above 250V). (R. 35).
  8. For the safety from supply lines and apparatus, earthling of lines, PPE to workers (gloves, rubber shoes, safety belts, ladders, earthing devices, helmets, line testers and hand lamps, for protection from electrical and mechanical injury), and authorized working on live lines are necessary (R36).
