NR NR/L3/ELP/25000/MODC ISSUE 1 PDF

This module applies only in areas undertaking the trial of the Single Approach to Isolations on 25 kV a.c. infrastructure as set out in the Scope of the main standard.  Within the trial areas, this standard supersedes all the requirements of NR/L3/ELP/29987. For all areas not involved in that trial, this standard does not apply and the provisions of the most recent issue of NR/L3/ELP/29987 apply instead.

Within the trial areas, this module specifies:

• The requirements applicable to all locations relating to the implementation of Local Earthed Isolations of 25 kV a.c. railway electrification, and

• The requirement to have in place a Local Earthed Isolation procedure to define the particular procedure for the implementation of Local Earthed Isolations at each particular location.

This module applies to Network Rail personnel and to Network Rail’s contractors working within the trial areas, when working on the operational railway with overhead electrification or when working off the operational railway but where the work presents the risk of encroaching within 2.75 m of exposed Live parts.

To provide a consistent approach for working and managing the interfaces between systems and parties, other Railway Group members may, as best practice, apply this module to infrastructure they control within or adjacent to trial areas.

Further requirements are contained in the Rule Book module AC (GE/RT8000/AC) and Handbook 16 (GE/RT8000/HB16), and in Network Rail’s Lifesaving Rules.
