Question

According to IE rules for service connection for low and medium voltage line, the height of service line conductors erected across a street must NOT be less than:
1. 5.490 m
2. 5.975 m
3. 6.10 m
4. 5.18 m

Answer 1

Correct Answer - Option 2 : 5.975 m

Clearance above ground at the lowest Conductor:

Voltage Level	Description	Distance
Low & Medium Voltage	Across a street	5.975 m
High Voltage		6.1 m
Low & Medium Voltage	Along a street	5.5 m
High Voltage		5.8 m
Low & Medium Voltage	Elsewhere than along or across any street	4 m
High Voltage		5.2 m
33 kV & EHV	Clearance above ground (+0.3 m for every 33 kV)	Min 5.2 m
