The electrician confirmed that it was not difficult to conduct the examination, but the details determined success or failure. Many of the zero-basic students had full theoretical scores, but were caught up in a small mistake of being real. Today, with high-level electrician experience, the most common points to be scored and the easiest to step on the pit are told once and for all, avoiding these mistakes and passing through with a steady and easy hand。
X. The ease of error (necessary, easy to lose points)
1. Error holes in the graph: the red pen was not plugged into the v-hole, the wrong current hole was inserted, a barometer was burned directly and failed on the spot。
2. Spacing error: direct flow of communication and electrical resistance, not only cannot be read, but also has security risks。
3. Measurements are irregular: both hands touch the head of the table metal, the examiner issues a direct violation, and security awareness does not pass。
4. Unstandard readings: table of indicators does not read, table of numbers does not look at slots, miscalculated and lost points。
Line connections are prone to error (highest scores, most failures)
1. Wires are not based on drawings: they are unconnected by perception, cannot match the lines, cannot connect the lines, and are re-examined directly。
2. The pressure line is irregular: wire skinning is too long, copper cores are exposed, and the pressure line is pressured to the insulation skin, which are typical points of deduction。
3. Sequenced swirling: a serious error was made when the right-hand side of the plug was written back and the switch was not controlling the wire。
4. Unorganized lines: without vertical lines and cross-disturbed lines, the examiner will determine that the operation is unprofessional and unsatisfactory。
Iii. Security operations are prone to error (one veto, one error)
Direct operation without electricity: the first step of the examination must be electrocuted, this step must be omitted and a direct finding of failure must be made。
2. No landlines, no warnings: high-pressure and control lines are physically operated, security measures are not in place and disposal is zero。
3.** electro-wire irregularities**: physical examinations are strictly prohibited, and tests are directly disqualified。
3. Errors in the use of tools: wires with screwdrivers, hand pulling of wires, direct decorating without specifications。
Iv. Irresponsibles of the electric power and the control line
1. The contact presses do not distinguish between 220 v and 380 v, burn the component directly after the connection and fail。
Self-locking, interlocking circuits back-to-back: point-to-point motion, long movement, typical logical error, difficult to remedy。
Non-inspection of direct access to electricity: complete failure to review, non-school lines, an electric jumper, all done in vain。
4. Dismantling lines are not sequential: first, then zero, wrong, safe。
V. Emergency emergency and fire freedom equipment (routing fixed, one wrong point lost)
1. Misorder of first aid: no power cuts, no direct rescue, no error of principle, no direct eligibility。
2. Inaccuracy by pressure position: cpr is biased upward or downward by pressure point, is not standard and the examiner is not given points。
3. Wrong type of fire extinguisher: electrical fire water extinguisher, foam extinguisher, error of principle。
4. The reporting process is incomplete: the examination officer is not informed after first aid, the site is not organized and the details are dropped。
Vi. Metrics and tools are easily misdirected (small errors, most unfortunate)
1. Errors in the use of plier current tables: the pliers are not closed and the two lines are stuck simultaneously and the measurements are invalid。
2. Unusual use of a rockometer: insufficient turn-off, miswire, invalid insulation insulation。
3. Non-return of the instrument: the examination is completed without organizing the tool, without cleaning up the site, with bad habits, and the examiner deductions directly。
4. Non-confirmation of power outages: failure to inspect electricity prior to route detection is a serious violation and a lack of security awareness。
Vii. High scores in practical examinations (summary of advanced electrician experience)
1. Look at the drawings and do something: look at the lines, the voltage, the components, and do not need to be wired. Slower than wrong。
2. Safety before operation: power checks, power cuts, listings, guardianship, and no less。
3. Wires are slow: one more check, line numbers correspond, colour norms ensure a successful powering。
4. Required review after completion: examination of pressure lines, fire, breakout, insulation, confirmation of correctness and raising of hands。
Electrotechnologies test not so much technical, but norms, safety and detail. The zero base can be passed once and for all by avoiding all the above error-prone points, strictly following the process, without panic or confusion. Remember: you'll get a good pass and you'll get a job。
