Installation of contact stock cables in buildings that have just been built, in the world of electricity, jobs like this are very easy and highly sought after by electrical officers, jobs like this are considered to be one of the most relaxed and easy jobs, because we work inside the room in the sense of the word is not exposed to direct sunlight, we rarely get assignments like this, almost 90% of our work is in the hot sun, climbing poles, connecting roadside cables, installing transformers, this kind of work is very, very tired.
For a job like this, we don't need a lot of members, just the two of us, and this job is also not the job of the office or from the boss, but this is our personal job, where the owner of this shop asked me directly to install their cables directly. come straight home.
At times like this we need more than one person, when some cables will be inserted into the paralon pipe we really need more power, what's more, the cable that we install here is slightly larger, because the estimated usage is a little bigger than ordinary houses and shops.
What makes our work easier, here we don't need to make a few holes in the concrete because the position has not been clearly determined by the owner, usually when installing cables in new buildings we have to make holes like small gutters so that the paralon pipes are neatly embedded and make it easier to install. later casting.
The MCB that we use this time is 4 MCB, the MCB function is to limit electric current and as a current safety, and to overcome excessive current, if the electric current enters excessively the MCB will automatically disconnect the electric current that passes the capacity that has been determined by the MCB .
One MCB is used for one valve which is used to secure one facade, while here we use 4 valves, with levers that we have put together so that if there is a disturbance in one of the valves, then all valves will also be cut off.
The basic workings of the MCB is to disconnect the circuit if one day there is a short circuit at a point such as connections and electronic items that are being used.
The following are the characteristics of an MCB:
• load current can be directly
decided if the heat is
generated in excess of the heat dissipated
receive, like the current from a meter
which has crossed the line.
• direct short-circuit current can be quickly disconnected without any time delay.
•after the MCB works like disconnecting the electric current the MCB can also be reused, not the same as a fuse that after working but cannot be reused.
