[SKYSQUARE Road-034-] Moving towards realization! 11th qualification ~Handling~

Hello

This is Nakajima from AZSTOKE Co., Ltd.

This is the purpose of this project.

Since there are some construction projects that cannot be done with just an electrician qualification, I will obtain the following qualifications.

In the previous blog, " [Road of SKYSQUARE-032-] Infrastructure electricity opened!! ~Electricity~ ", electricity has finally been turned on to the building.

We were planning ahead, assuming that electricity would be restored and various electrical work would be carried out.

As we proceeded with the plan, we discovered that some tasks would be difficult for an electrician to perform alone...

Here we go again... (-_-;) I learned that if I wanted to do the work, I would need to take another special training course, and that I would not be able to do electrical work in this condition.

I also thought it started from knowing that I couldn't do it without a license.

Since this is already my 11th qualification, I'll give up and start working towards obtaining it.

The qualification is called "Special Training for Low-Voltage Electrical Handling Work."

1. About previous qualifications

I am currently working towards obtaining my 11th qualification.

Here are the qualifications I have so far.

Large Class 1 vehicle: Obtained
Towing vehicle: Acquired
Large special vehicle: Acquired
Vehicles, construction machinery, ground leveling, etc. (digging, leveling): Acquired
Vehicle, construction machinery, leveling, etc. (new demolition): Acquired
Small mobile crane: Certified
Off-road transport vehicle: Acquired
Slinging: Acquired
Chainsaw felling, etc.: Acquired
Type 2 Electrician: Acquired
Special training for low voltage electrical work ←Now here

★Special training for low voltage electrical work

In the first place, it seems that this qualification is required for all work that involves connecting to an already energized point such as a distribution board, which leaves one wondering whether one would only be able to do wiring work on things that are not connected to a distribution board in newly built houses, etc. However, if one has received special training as an electrician and in low-voltage electrical work, one will be able to perform most electrical work as long as it is low voltage, so it is definitely worth getting.

Studying for a qualification and the increased ability I can achieve thanks to having a qualification

This has led to many new encounters that I had never imagined.

The results are significant, and they also help create new sound expressions.

I am always looking to acquire any qualifications I think I might need.

2. Take the course at a driving school in Ichikawa, Chiba Prefecture

Now let's start with qualifications.

If you are in Tokyo, you can take the course at the Ichikawa Center.

I'll be there at 8am in the morning.

Maybe it's because of the job, but I have to start early in the morning...I can only endure it for a few days, but it takes a lot of energy.

This qualification requires a total of two days of attendance.

Day 1 (7 hours): Academic
Day 2 (7 hours): Practical

Just like studying at school, you take a class for an hour and then take a 10-minute break.

3. Understand the dangers of electricity

The core of the subject is to understand the dangers involved in handling electricity.

You will also learn how to avoid electrical accidents and understand how to respond if an electrical accident occurs.

First, we learned about the number of electrical accidents and the amount of pain caused by the amount of electricity.

However, since this is an area that can only be understood through numbers, electricians also study this type of thing and understand it.

Electricians also study most of these things, but this book provides more detailed information on the parts they deal with.

4. 400 yen lunch box during lunch break

There will be a 45 minute break after the 3 hour period.

If you purchase a meal ticket at the start time of 8am, you can buy a bento box.

If you don't buy this, there are no supermarkets or convenience stores nearby, so the only way to buy it is to eat cup ramen from a vending machine.

What's more, it's quite cheap at 400 yen, but by collecting the lunch boxes, they are cutting costs and improving the contents, which is great!!

It was packed with vegetables, making it a healthy lunch box and very delicious.

5. There was one thing I didn't understand...

The first day of classes has ended.

There was one point I didn't understand here.

During the course, I had the opportunity to watch a DVD, which explained that there were some construction projects that could not be carried out without this qualification. One of the projects mentioned laying and modifying underground Anyflex pipes, and to be honest, I didn't understand the details.

I thought that since there was no electrical wiring involved in laying the pipes alone, wouldn't a license be required for laying the pipes, regardless of whether it was for making changes? But honestly, I wasn't sure until the end.

I asked the teacher after the first day's class ended.

Honestly, the teacher doesn't really understand...

I would have liked to have understood that, but I decided that it was okay since with this qualification there was nothing I couldn't do.

However, the first day is over.

Wow, I'm pretty exhausted even though I've only been doing it for a day...

6. Day 2 is a practical test

The distribution board used in the practical session on the second day seemed quite similar to the one at SKYSQUARE, and I thought it would be helpful to be able to learn in a practical way.

Electricity is supplied to this distribution board, and students will learn practical knowledge about sensors, such as how to check whether electricity is being supplied and how to check the amperage used.

I learned that it is difficult to judge electricity just by looking at it, and there is a possibility of accidentally getting electrocuted if electricity is applied, so it is essential to understand how to use inspection tools.

I felt that it was important to get hands-on experience here.

Even if a task can be done without any qualifications, I think it is better to have knowledge of the dangerous parts and understand how to prevent them from happening.

This is the SKYSQUARE distribution board.

It was very similar to the practical exercise above and I learned a lot.

7. Understanding the importance of electroscopes

First, you need to know if the wire is live.

The sensor that checks this is shown in the image.

There are many different voltage detectors made by various companies, and I have tried them out with various things.

It has a unique flavor, so I wonder which one I should buy...

For now, I understand that it won't be practical unless it's a type that can detect voltage even through the coating, so I'm thinking of looking online and purchasing something that can do that.

8. Understanding the importance of clamp meters

In the practical section, we learned how to check the amperage of the electricity used. There are many other things you can check inside the meter, but I thought it was great to be able to check the amperage of the electricity used.

You can also check the actual usage figures for various types of electricity you are currently using, so you can check whether the wire thickness is okay or whether the outlet is amperage-appropriate.

I thought it would be good to understand the problem.

I felt it was important to purchase this and actually try it out on the SKYSQUARE distribution board.

9. Understanding the importance of ground resistance

I wasn't able to take a photo so there are no images, but this is an understanding of ground resistance.

This is what is called earth.

I had only learned about earth wire installation from textbooks, but in order to actually install it, I used an installation resistance meter to check the resistance level and confirm the depth of the ground, so I was able to perform Type C and Type D installation work.

I was able to confirm my understanding by seeing the actual situation, which helped me to deepen my understanding.

10. Understanding the importance of insulating protective equipment and gear

Until now, we have been studying how to detect electricity flow and usage.

It's about the protective equipment and gear to prevent people from getting electrocuted in the first place when handling it.

I thought this was also quite important.

Of course, it was a big help to actually be able to touch and demonstrate these things.

I strongly felt that it was important to ensure multiple levels of safety.

I didn't have any gloves so I quickly bought some on Amazon.

I will be sure to wear these gloves when working with electrical wiring.

I haven't looked into whether the helmet is suitable for electrical work, so I would like to check the specifications of the helmet I currently have before purchasing one.
