  17. What are the LOA in feet for 12+25kV, columns 4, 3, 2 and 1?
    10, 4, 2.5, 1.5 - SPR 400
  18. Who does Column 4 of the LOA table apply to?
    Unqualified Workers and their equipment. SPR 400
  19. Who does Column 3 of the LOA table apply to?Qualified Electrical Workers uninsulated equipment and unqualified workers who are continuously supervised. SPR 400
  20. Who does Column 2 of the LOA table apply to?
    Qualified Electrical Workers (Normal Limits) SPR 400
  21. Who does Column 1 of the LOA table apply to?
    Qualified Electrical Workers (Absolute Limits) SPR 400
  22. When does a CUA require an ANRP?
    When they are working closer to conductor than LOA Column 4 and haven't received a protection extension. SPR 400
  23. What table lists distances regarding limits of approach?
    SPR Table 401
  24. What exactly does SPR Table 401 define?
    "Limits of Approach Table 401 lists the distances that shall be maintained between workers (including their extension of reach caused by conductive tools, materials, equipment or unplanned movements) and exposed electrical conductors or equipment."
  25. Scenario: At station TS1, 25CB52 has a LLP tag on it. Suddenly, 25CB1 and 25CB4 trip open, de-energizing 25F51, 52 and 53. No other breakers operate. Assuming all other conditions are fit for a bus reclose, can 25F53 be re-energized via bus breakers? Should 25CB53 be opened prior to a bus reclose? Should the permit holder be contacted?Image Upload 1
    According to SPR (423 & 424) the bus can be re-energized with 25CB53 left Closed and the permit holder doesn't need to be contacted since his portionof the circuit was " "de-energized by other than its own protection". SPR 400
  26. Can a single crew be working on multiple phases or tasks on energized conductor at the same time?
    No, they must be focused on the same phase / task. Other tasks may be carried out at the same time but only if they aren't on energized conductor. SPR 416
  27. When multiple qualified electrical workers are working on energized O/H conductor, can they work from different structures / aerial lifts?
    In most cases, no. The only exception being when removing or installing "hot-taps" where 2 separate aerial lifts may be used. SPR 416
  28. At what voltage do Live Line rules come into play?
    750V - SPR 417
  29. What is the minimum voltage that "barehand work" is allowed?
    60kV or higher. SPR 419
  30. When should phasing tests be done?
    Whenever incorrect phasing could occur. Ex: 1) Replacing Pothead Jumpers / Risers 2) UD Switching (making loops).
  31. What sections of the SPR describe requirements for LLPs and ANRPs?
    Sections 423 and 424 of the SPR describe requirements for LLPs and ANRPs respectively.
  32. How do LLPs or ANRPs provide personal protection in case of direct contact with an energized conductor
    They don't! "[LLPs and ANRPs provide] no personal protection in case of direct contact with an energized conductor or equipment." SPR 423 & 424
  33. Regarding LLPs and ANRPs, what does the worker's protection depend on?
    "The worker's protection depends on proper work practices and approved, tested, and well maintained live line tools." SPR 423 & 424
  34. SPR Rule 423.6 says: "When a Live Line Permit is in effect, the circuit involved shall not be paralleled without notifying the permit holder." Why isn't there a similar rule for ANRPs?
    When a parallel is made between circuits, protection settings for the those circuits become unpredictable. If a fault occurs due to contact between a worker (or their equipment) and some conductor, the reclosing device being used for the permit may not operate at all, resulting in a dangerous situation for workers with permits to be working on the line. Since holders of ANRPs are supposed to be working near energized conductor and not on the conductor, there is no personal safety risk since they would not be "in the bite" if there was a problem. SPR 400
  35. Can a CUA remove trees or portions of trees that are in contact with energized primary conductor using an ANRP?
    Only if they work under an existing Self Protection or Clearance or a Protection Extension. SPR 400
  36. Under what conditions should PLTs refrain from performing live line work?
    During fog (must have good visibility), rain or lightning (and for 15 minutes after the last lightning is seen or thunder is heard). SPR 400
