Inspection of signalling cables and wires as specified in NR/L3/SIG/11655.
Purpose
This standard describes how an inspection of signalling cabling and wiring is to be undertaken to identify signs of degradation
When the insulation degrades, the inner conductor may become exposed and come into contact with other exposed wires and terminals. The risks are that:
• Contacts are bypassed in a circuit
• Introduction of connections between different circuits
The other risk being to staff is of electrical shock, especially when carrying out hand tracing.
