protection, ground-fault—a means of detecting and interrupting a ground fault current at a level less than the current required to operate the circuit overcurrent device.
protection, overcurrent, branch circuit -— a device capable of providing protection for service.
feeder, branch circuits and equipment over the full range of overcurrents between its rated current and its interrupting rating.
protection, overcurrent, supplementary—a device intended to provide limited overcurrent protection for specific applications and utilization equipment. This limited protection is in addition to the protection provided in the required branch circuit by the branch-circuit overcurrent protective device.
protection, overload, motor—protection required for motor circuits that will operate to prohibit excessive heating due to running overloads and failure to start.
protection, short circuit, branch circuit — a device capable of providing short circuit protection for feeder and branch circuits and equipment, over the range of overcurrent above its rated overload current up to its rated interrupting current.
protective device—a device used to protect an electrical circuit from an abnormal condition.
short-circuit — unintended impedance placed directly across an electrical circuit to another element of the same circuit, to another circuit or to ground. Short-circuit currents do not flow within the complete intended path. Short-circuit conditions result from abnormal connections and do not include normal leakage currents.
transformer, class 2—a transformer complying with ANSI/UL 5085-3 or CSA C22.2 No.66.3.transformer, isolating一a transformer having no electrical connection between the primary and secondary windings.
transient suppression device—a component or assembly of components that limits the transient voltage, such as a voltage clamping device, a transformer with isolated windings, or a suitably located damping impedance or a combination of these devices.
transient voltage not limited — a condition wherein an apparatus or circuit does not employ a component or assembly that limits the peak transient voltage.
transient voltages, known and controlled (transient voltage limited) —a condition wherein an apparatus or circuit employs a suitable component or assembly that limits the peak transient voltage to a specified value.
wire bending space — a space opposite field wiring terminals or any other space in which it is intended that field wiring may be bent or offset.
wire binding screw — a screw used to fasten an unprepared conductor that is looped around the shank of the screw and secured under the head of the screw or a prepared conductor that is assembled about the screw shank and retained by the head of the screw.ASME A17.5 pdf free download.
