Wire Off Procedure

Question 1

Wire Off Procedure

(Detailed)

Answer 1

1. STEP BACK – State you need to ‘ENACT WIRE OFF PROCEDURE’
   a. Take PHOTO of:
    Wire
    Host
    Context
    Prints
2. Inform D-SIM (You have found a wire off) and Request:
   a. AWC
   b. 2nd Competent Person (To attend site)
3. ISOLATE (Preferably after the Capacitor)
4. Gather sufficient EVIDENCE for AWC:
   a. Hand Trace (highest form of proving)
   b. Identify Physical Attributes:
    Cable Type
    Size / Length
    Colour
    Labelling
    Numbering
5. Remove Isolation (REINSTATE Power)
6. ELECTRICALLY PROVE:
   a. Test both sides to Earth (1 = 100v / 1 = 0v)
   b. Test Wire to Host (To prove Host is NX Potential)
    Break circuit BX SIDE to lose Voltage proving wire is part of circuit (Closest to wire)
    Break circuit NX side to lose Voltage Proving host is part of circuit (Closest to Host)
7. PRE – Wire Count (With 2nd Competent Person)
   a. Must be INDEPENDENT / Diverse checking (Do not lead)
   b. YOU = Check Prints - HE/SHE = Counts at Terminal
   c. Confirm Discrepancies (Ask to Repeat)
8. Confirm AWC issued with D-Sim (Request AWC number)
9. ISOLATE
10. RECONNECT Wire to Host (Take picture)
    a. Clearly LABEL:
     Date
     Name
11. POST – Wire Count (HE/SHE checks work)
12. REINSTATE Power (Observe Track Pick-up)
13. Clear AWC – REQUEST NIGHT CHECK
