斷路器是在電路板上使用的電氣設備。他們適當地監視和控制電氣系統或任何種類的設施的數量。這就是出現硬件問題的原因,因此必須檢查斷路器是否是造成這種情況的原因,並且必須將其更換。斷路器可以控制和保護電路並進行操作。
為了提供良好的條件和安全性安裝,產品必須進行測試。註冊電氣人員通常建議進行購買前先檢查,使用測試燈或儀表套件檢查電源是否安全。
在仍然有電源流過的電路板上安裝斷路器是不安全的。如果在切斷電源之前,如果服務斷開開關或主斷路器以外的電氣開關上有電,則不要繼續操作。
有使用儀器的標準測試程序。對電路進行了測試,以確保它們受到正確的設備保護,並且在發生故障時可以接地保護它們。那裡的接地導體可以快速帶走任何雜散電,並啟動安全裝置(保險絲,MCB,RCD等)。 註冊的電氣工人會提供測試,以驗證安裝後設備是否正常運行。
Testing is necessary to provide good conditions and safety of installation. A pre-purchase inspection is often recommended by a registered electrical worker. Use a test light or meter set to check for the presence of power.
It is not safe to install a circuit breaker in an electrical board that still has power flowing to it. Do not continue if power is available on an electrical switch other than Service Disconnect or Main circuit breaker until the power source has been cut off.
There is a standard test procedure using instruments. Circuits tested to see that they are protected by the correct device and that they have earth to protect them in case of faults. The earth conductor is there to take any stray electricity away very quickly and activate the safety device (fuse, MCB, RCD to name a few).
The registered electrical worker provide the testing, to verify proper functioning of the equipment after installation.
