Section R.79 of the Indian Electricity Rules, 1956, pertains to safety clearances and restrictions related to overhead electric lines and their interaction with buildings and other structures. It aims to regulate the safe installation and maintenance of electrical lines, ensuring public safety while balancing the rights of property owners.
Section R.79 mandates specific clearance requirements from buildings for low, medium, high, and extra-high voltage lines. It prescribes the minimum vertical and horizontal distances that electric lines must maintain from structures to prevent accidents and ensure safety. The section also provides for penalties in case of breaches of these clearance rules.
The section covers:- Overhead electric lines of low, medium, high, and extra-high voltage.- The clearance distances from buildings and other structures.- The responsibilities of electrical authorities and workers during installation.- Enforcement through penalties for violations.- It applies nationwide, ensuring uniform safety standards.
Penalties for violations include fines, which may extend up to two hundred rupees or more, depending on the breach. Specific rules (e.g., Rule 141) stipulate penalties for non-compliance, such as unauthorized work or failure to maintain prescribed clearances [Sources: "BHARAT PLYWOOD AND TIMBER PRODUCTS PRIVATE LTD. VS KSEB", ""].
In summary, Section R.79 of the Indian Electricity Rules, 1956, establishes essential safety standards for overhead electric lines, balancing public safety with property rights, and prescribing penalties for violations. Its provisions are justified as reasonable, within the scope of delegated authority, and aimed at preventing electrical accidents while ensuring fair compensation for property owners.

Section R.87 of the Indian Electricity Rules, 1956, addresses the safety concern related to lines crossing or approaching each other, emphasizing the necessity of protective measures to prevent electrical hazards and ensure safe clearance between overhead lines and other infrastructure.
Section R.87 stipulates that when an overhead electrical line crosses or is in proximity to another line, the owner of either line or the entity laying the line must arrange protective devices or guarding arrangements. These measures must be in accordance with the prescribed Code of Practice, to prevent accidental contact or interference.
This section applies to all overhead electrical lines crossing or approaching telecommunication lines or other electrical lines. It mandates safety measures to prevent accidents due to lines coming into contact or proximity, thereby covering the safety protocols during installation, maintenance, or modifications of overhead lines.
The Indian Electricity Rules, 1956, generally prescribe penalties for violations of safety rules, including fines and other punitive measures. Specific penalties under R.87 are not explicitly detailed in the available sources, but breaches may attract fines or penalties under Rule 141, which covers penalties for breach of rules [Source: "THE INDIAN ELECTRICITY RULES, 1956 - R.141"].
This concise legal commentary synthesizes the essential aspects of Section R.87 of the Indian Electricity Rules, 1956, based on available sources and emphasizes the importance of safety, responsibility, and compliance in electrical line crossings.
