现在很多人都会在装修的时候，把我们的家交给装修公司去，殊不知装修公司的操作，其实并不是百分百规范的。水电是我们家里关系都很重要一个环节，如果电路改造出现失误，就会给我们家里造成很大的隐患。毕竟电路是隐蔽工程，我们在平时的时候难以发现问题存在，一旦出现问题就会损失惨重。所以为了我们的家居安全，一定要知道布电雷区。

一、布电雷区

裸线埋墙

按照相关规定，电线埋墙时必须穿保护管。而某些施工队利用大家对电路的不了解，将电线直接埋入墙内，导致電線容易老化和破損。如果想要更换非常困難，需把牆面重新凿開，把電線穿管後再填埋。

管内電線“超載”

按照電工施工規範，放置的導線截面不超過管子的1/3面積。而在實際施工過程中，有些電工師傅為了減少用料，一根管內塞進很多根電線，會縮短保護管使用壽命。電路驗收發現問題：一根電線管內穿5跟線。

強弱電共管

某些不負責任的施工隊把強電和弱電electric wires放在一個套管或盒內，以節省一根管或盒子的同時也省時省力。但這樣做會導致強electricity對弱electricity產生信號干擾，如照明electricity產生的electromagnetic waves會對網絡電話line信號產生干擾。一旦負荷過大，便易於燃燒wire.

接頭處不設過渡盒

Electric wires鋪設時，有可能長度不足需要接線，而有些施工隊接完wire後，不加overload box直接套入pipe interior而非設立overload box。在此後期如果有任何問題檢查就非常困難，所以當進行鋪設時應該設定overload box.

開槽轉換

大家都知道Electric circuitry and water system 在鋪設時，都需要在牆面或地面上開槽，但千萬不能任由施工人員隨意在牆面的開槽（例如承重牆不能開槽）；地面開槽時也需注意避免破壞樓板和地面的防水層.

二、存在危險

危險一：裸线直接入walling material

部分裝修師傅為了省成本省時間，用工具打通小孔將三條裸线一起嵌入到walling material中。時間久了，由於walling material反潮會氧化wire insulation，使得整條wire insulation變薄增加故障率。

危險二：未按規範走行 Electric wiring pathways

硬裝完成后期安裝皆需打钉裝五金零件及裝飾品等，但是裝修時走行 Electric wiring pathways 不按規範走隨手斜向走行不知道walling material裡有哪些line route，在進行安裝如突然遇到斷路情況極有可能必須破壞剛處理好的walling material！

危險三：横向开slotting超过standardized dimensions.

据調查，一些無法遵守標準規則與程序且只追求速度效率之建築業者，在執行工程期間經常出現於牆體表面的水平方向open slots for electric wiring situations，這種做法雖然看似能夠減少布线用的pipes长度並節省成本，但卻嚴重破壞了建筑物結構安全性。此外，這種横向open slots even on load-bearing walls 是非常具有風險性的，因為它們幾乎等同于將玻璃划过，它們只要遭受强烈的地震震动即可崩塌。在專家的建議下原則上輕質walls 的横向open slots shouldn't exceed 50 centimeters, while those in load-bearing walls should not exceed 30 centimeters.

三、建設注意事項

Left Zero Right Fire (LZRF)

Switches and outlets should be installed with the neutral wire to the left of the live wire.

并头连接 (Parallel Connection)

In household renovations, electrical wires can only be connected in parallel fashion using connectors that are pressed firmly into place, ensuring a secure connection before wrapping with insulating tape to protect against moisture damage.

3.Add Switch Boxes:

When laying out electrical circuits, it's important to add switch boxes when necessary - ideally every 15 meters or so - especially if there are any bends or turns along the way that might require additional connections or rerouting of cables.

4.Vigilant Inspection:

After completing all electrical installations, conduct a thorough inspection using a multimeter to verify proper functioning of all switches and outlets; check for any signs of overheating or other potential safety hazards such as frayed cords or exposed wires; ensure that all connections are securely fastened without loose screws or bolts; inspect cable lengths and condition for wear & tear signs like cuts/cracks/burns etc., which may lead future problems down road time later on!

5.Documentation & Record Keeping:

Take photos documenting each installation step by step throughout your home renovation project including pictures showing completed work at specific points where changes were made during construction process itself! This helps keep track record history detailing what was done when/how many times it has been changed over years since initial build date till now until last updated version becomes outdated due aging materials degradation factors affecting performance reliability functionality lifespan expectancy value money spent invested cost savings long-term maintenance repair replacement costs too high expensive unaffordable!
