As old saying goes: If you often walk along river, your shoes will never get wet. In electrical industry, although many people are aware of dangers and exercise caution, mistakes are still inevitable. Below are some of mistakes that almost every electrician will encounter.

Nine out of ten electricians were electrocuted! The following operations will undoubtedly increase risk of electric shock.

The more you work, more you're afraid: 90% of mistakes that electricians can't avoid, don't be careless

1. During power outage maintenance, forget to check power, take a risk, or do a careless power test, which will cause switch to trip or reverse power transfer.

2. In face of long power lines/cables, frequency converters, soft starters, reactive power compensators and other electrical equipment that is turned off, if you do it directly without discharging, you may be one to get electricity. shock.

3. Some people trust electric pen too much and don't connect ground wire. I guess I'll have to be a little patient too.

Everyone who works as an electrician knows that old electricians often get electrocuted, but very few new electricians. Many electricians say that more they do it, more they get scared. With a wealth of experience, many electricians are hesitant to ignore design details or even blindly confident in themselves, which is often beginning of danger.

02. The measurer forgot to change gears, multimeter was written off

The electrician has just tested equipment with "resistance" of multimeter. He wanted to turn on power and then measure things like voltage/current, but he just forgot to change gear on multimeter. When you press test pen, there is a pop and a little black smoke: multimeter is defective! I was amazed and turned to buy another watch. Many people change three or four multimeters a month.

03. Record knowledge, avoid copying in real work

When choosing electrical equipment, wires and cables for work or operation, some colleagues simply adhere to theoretical knowledge from books and, after a little calculation, make final decision. Actual power consumption is simply ignored, resulting in constant crashes after completion and even equipment scrapping.

Electrician's example: When calculating a single-phase load, calculation is based on a three-phase load, and it is used as a selection standard. After laying cable, it actually burned right out!

04. Inspection required after completion of work, and no equipment and tools left

After work was completed, tools and materials were not taken away. I don’t know how many pliers, screwdrivers, electric pens, multimeters are left at customer’s house. good or bad after repairing equipment. He immediately left without reminding customers of seriousness, which led to repeated improvements, but ended in complaints and a waste of time.
