Master electrician Alexander Laub – HAZET industry story

In short, we offer every electrical installation service imaginable. We install intercom and telephone systems, networks and SAT systems. Photovoltaic power systems also fall within our scope of activities. If you want to generate your own electricity, you are welcome to ask us about a suitable photovoltaic power system concept.

Even at the age of just 16, I really wanted to learn a trade. Since I am enthusiastic about technology, I decided to train as an electrician. A long time has passed since then, but I have never regretted my decision.

The variety. Every day we get the chance to see something new. At times we work down in basements, others on top of roofs. And due to advances in technology, we are often faced with new challenges.

The most important thing is to have a passion for physics, mathematics and technology. Diligence and the ability to work in a team are, of course, also important. A good level of physical fitness never hurts, but that usually comes automatically with the job.

Every good electrician works according to the 5 safety rules of electrical engineering. If you follow these rules and can trust your employees and no electrical accidents will happen.

The 5 safety rules of electrical engineering at a glance:

1. Disconnect from the mains
Disconnecting is the process of disconnecting all poles of an electrical system from live parts.

2. Secure against reconnection
Prevent the system from being switched on accidentally. A restart must be reliably prevented. In the low-voltage network, simply replace the blown-out fuses with lockable blocking elements.

3. Verify that the system is dead
The very act of verifying absence of voltage with a voltage tester is considered working under voltage. Is the system now actually voltage-free? Use a "suitable testing device", e.g. a voltage tester, to verify the absence of voltage at all poles. Before using it, however, you must check that the voltage tester is functioning properly.

4. Carry out earthing and short-circuiting
If the system is voltage-free, connect the conductors and the earthing system with short-circuit-proof earthing and short-circuiting devices.
Important: First earth then short-circuit!

5. Cover or fence off adjacent live parts
According to the 5 safety rules of electrical engineering, adjacent live parts are defined as parts that are within the vicinity zone.
If parts of an electrical installation in the vicinity zone of the work location cannot be disconnected, additional precautions must be taken before starting work. In this case, use insulating protective shutters or covering material as protection against accidental contact with live parts.

We first meet at the office to discuss and assign the day's tasks. Then the teams travel to each of their respective construction sites. The call outs are so varied that every day is different. In the evening, the teams meet back at the office or head straight home.

During my apprenticeship in 1996, I naturally followed the events of the Düsseldorf Airport fire. Since then, fire protection has been made a priority. Even today, the requirements are being expanded and the work is becoming more and more demanding. The days when an electrician simply laid cables are long gone. Today, you have to develop an understanding of how the devices that make up complex systems communicate with each other.

We once got a call about a socket dripping water. That was really crazy! But we quickly got to the bottom of what caused it: The roof insulation had been damaged and had allowed rainwater to enter the socket via the cable.

It has long been known among mechanics that HAZET tools stand for first-class quality.

This quality is also reflected in the HAZET tools we use as electricians. They are extremely resilient and just feel great to use.

That's why I'm looking forward to HAZET releasing more products that are relevant to our industry.
