NR NR/SIN/114 ISSUE 1 PDF

This Special Inspection Notice applies to

• organisations that maintain non-traction HV switchgear that is included in the Ellipse database.

It is recommended that electrical supplies to buildings within other disciplines within Network Rail, for example, franchised stations, depots (both in use and redundant) and similar, adhere to this process.

Purpose

It is suspected that a number of electrical distribution switchgear items with dependent manual operation remain on the Network Rail distribution system.

The intention of this SIN is to identify all switchgear fitted with a dependent manual operating mechanism to support a parallel Letter of Instruction which applies a ban on the live operation of this switchgear. At the same time, a list of such switchgear will be made which will assist in its replacement programme.
