The posts shown in this document are the standard means for providing such physical protection. Suitable alternatives to these protective posts may be proposed by the applicant for PG&E''s approval.
Minimum Approach Distance Chart
The chart is particularly crucial for workers involved in transmission and distribution operations, where the potential for electrical hazards is high due to the system voltages present.
Electrical Clearances: Requirements and Safe Distances
Electrical clearances are the minimum separation distances the National Electrical Code (NEC) requires between wiring, panels, overhead conductors, and everything around them. These
How It Works: Electric Transmission & Distribution and Protective
Distribution systems, typically rated below 34 kV, can tie directly into high-voltage transmission networks or be fed by sub-transmission networks via “step down” substations.
