Amtrak electric traction questions with
complete solutions
Anchorage - correct answer ✔✔ The terminating component of a fall protection system or
rescue system that is
intended to support any forces applied to the system. (SOI‐214)
ark flash - correct answer ✔✔ An arcing fault is the flow of current through the air between
phase conductors or
phase conductors and neutral or ground. An arcing fault can release tremendous amounts of
concentrated radiant energy at the point of the arcing in a small fraction of a second resulting
in extremely high temperatures, a tremendous pressure blast, and shrapnel hurling at high
velocity. (SOI‐201)
arc flash boundary - correct answer ✔✔ An approach limit at a distance from exposed live parts
within which a person could receive a second degree burn if an electrical arc flash were to
occur. (SOI‐201)
arcing by product - correct answer ✔✔ SF6 gas subjected to electric arc heat causes the gas to
decompose into
potentially toxic by‐products. (SOI‐216)
Arc-rated - correct answer ✔✔ The property of a material whereby combustion is prevented,
terminated, or
inhibited following the application of a flaming or non‐flaming source of ignition, with or
without subsequent removal of the ignition source. (SOI‐201)
, authorized person - correct answer ✔✔ - A Qualified employee assigned to perform duties at a
location where the
employee will be exposed to a fall hazard. (SOI‐214)
authorized work area - correct answer ✔✔ The area established by the Class "A" employee
where work may be performed. (SOI‐211)
Class A - correct answer ✔✔ Electric Traction employees and their supervisors, approved in
Electric Traction
service, competent to erect, repair, and maintain electric apparatus, and to supervise and
protect other persons performing work in electrified territory. C&S employees and their
supervisors competent to install, maintain and repair the high voltage signal power system
under their jurisdiction. (SOI‐211)
clearance - correct answer ✔✔ A document that outlines the procedure followed by the Electric
Traction
department when it is necessary to remove power from circuit(s)/apparatus in electrified
territory. (SOI‐201, 206, 211 & 223)
Deceleration distance - correct answer ✔✔ - The vertical distance between the user's fall arrest
attachment at the
onset of fall arrest forces during a fall, and after the fall arrest attachment comes to a
complete stop. (SOI‐214)
dry testing - correct answer ✔✔ - A method of measuring leakage current between test
electrodes that is not
measurable with a wet test. This testing is similar to testing performed at time of
manufacturing. This type of test can be used on new or old live‐line tools to detect defects
