The thing is like this, a customer called a few days ago and said that the leakage switch of the cutting machine in his factory had tripped and could not be pushed up, and wanted me to help. After understanding the basic situation, I feel a little bit at the bottom of my mind. Since it is a trip, it is a leakage other than a short circuit. It should not be troublesome to repair. precision cnc customized stainless steel fabricators los angeles
When we arrived at the scene, as soon as we opened the distribution box, a pungent plastic smell hit our face, and we knew without looking what components must have been burned. After inspection, it turned out that a contactor was burned, and the contacts and the distribution box shell touched together, causing the leakage switch to trip. Explained the reason to the boss and replaced a new contactor.
Before leaving to settle accounts, I told the boss that the power distribution cabinet was not well sealed, and there was a thick layer of dust inside. The contactor burned out this time, most likely because of too much dust. It is recommended to clean the distribution box when you are free, otherwise it will be broken at a critical moment and it will easily delay things.
I just made a suggestion like this, the boss asked me to help clean it up for free, and I will have more friends to introduce it in the future. Normally speaking, if the problem is solved, the money will be collected and the person will leave. One more thing is worse than one less thing. But I’m a passionate person, and I can’t stand the other party’s soft-heartedness. I thought that since I don’t have other things at hand, I should just help out. precision cnc customized stainless steel fabricators los angeles
Because of this move, not only did I not get the maintenance fee, but I also took in 2,000 yuan.
Because I was worried that dust and iron filings would fall into the components and cause a short circuit, I carefully brushed off the dust and iron filings on the components with a brush. It took nearly 20 minutes, and after repeated inspections, I started to send power . Unexpectedly, I was still too young. When the power was turned on, there was a bang, and a circuit board inside smoked, and the machine could no longer be turned on!
In the end, the free help failed, and I lost 2,000 yuan. So here I would like to remind all colleagues, don’t worry about cleaning up the dusty power distribution cabinets everywhere, otherwise you may lose your wife and lose your army. precision cnc customized stainless steel fabricators los angeles

Electrician B: After the factory is dusty, be careful. Turn off the main power supply, and try sending the auxiliary wires. Otherwise, the consequences will be serious if it encounters electrical conductors or flammable substances.
Electrician C: Electrical dust removal is not a trivial job, it is a serious work item. You should do your duty as a helper, and save the boss a lot, at least 3,000 yuan, 1,000 yuan for maintenance and dust removal, and 2,000 yuan for equipment costs. precision cnc customized stainless steel fabricators los angeles
