It is very often that when fire happened to a house or somebody got electric-shocked; then the first suspect is due to improper installation of electricity. That is the reason electrical installation shall be performed by qualified technician.

Here, I want to introduce you, if you don’t know yet, how to protect our asset from being fired and our self from getting electric-shocked.  European standard IEC 60479 has explained the magnitude of current and its effect when flowing through human’s body; while risk of fire can be reduced through reduction of overloading risk and ensuring the protection to cut off the fault. To fulfill both purposes, there is only one means, which is GROUNDING.

Remember, Protecting life and asset → grounding.

How can we ensure that we have a proper grounding?
1. Always use cable with 3 cores with one of them having yellow-green strip color.

2.Ensure the yellow-green cable BONDED at body of the equipment.

DONE!! that’s all all steps to keep safe.

Now, after the grounding system has been installed, ensure that your home is completed with ELBC or GFCI.

So, when fault is occured (either electrical shocked, or ground fault, symbolized as lightning), the electrical source are cut off (symbolized as X).

Dengan sepenuh kesedihan, ditempat kerjaku ada dua berita kecelakaan karena listrik diminggu ini. Yang pertama, seorang electrical super senior, terkena arcing flash ketika bekerja di switchboard dengan short circuit capacity 30 kA. Beliau menderita luka bakar cukup parah di bagian muka dan tangan. Mata selamat karena memakai kacamata, tetapi seluruh kulit muka terbakar. Karena bekerja dengan lengan pendek, tangan bagian bawah saja yang gosong.

Kecelakaan listrik yang kedua menimpa istri office boy. Kesetrum ketika mencuci pakaian dengan mesin cuci. Sekarang koma dengan kulit menghitam.

Ada dua hal yang perlu kita sadari, :

1. Jangan anggap remeh listrik walaupun kita sudah sangat senior/berpengalaman dibidang listrik. Listrik adalah \textit{perfect killer} untuk orang yang tidak menghargainya.

2. Kita perlu kritik PLN, mengapa PLN tidak mewajibkan seluruh konsumennya memakai ELCB? dear pembaca, pasanglah ELCB untuk keselamatan rumah tanggamu seperti yagn pernah kutulis di http://setrumsetruman.com/?p=385.Jangan terlalu pelit untuk keselamatanmu.

Salam setrum dan jangan kesetrum.
