勞作 修理雙切開關 109.04.05

客廳的雙切開關壞了 客廳的燈是大門入口和樓梯雙切的
壞掉的是樓梯那一邊的雙切開關

先學會家裡的總開關箱 修理開關以前 先關閉電力開關
順便熟悉一下 家裡的電器配電 包括 鐵捲門 揚水馬達 電燈 插座 廚房 冷氣
整個房子的總開關 還有過載保護電驛






用三用電表 測一下 確定插座沒有電


輪流拆卸開關









拔掉舊的開關



量一下開關的電







裝上新開關



































舊開關的樣子




換上新開關了

太小了,不小心會被電到的,可以教他們殺豬,以便日後當醫生喔

even if the power is off ...

... it's not a good idea to "experiment" with your home installation

possible draw-backs ::

• Al+ wires don't like much bending

• when assembling the "outlets" back you must ensure the "safe"/correct placement of wires , no (exessive) stress to contact points , the "safe clearances" (without mecanical tension/stress) in between wires ← is unlikely to cause the short circuit in case of normal grid conditions - but there might be spikes at/after the "power failure" - so you do not want to compromise your safety - while not at home and can't fast react on events
_____

other than that -- you must always be aware/know your "potential" relative placement in electrical circuit - it is constantly aware state , constantly aware planning and committing your movements . . . especially with the high voltage

not trying to scare you off the learning . . . just you must "address" everything here . . . at all times

the moisture and oil conducts ~AC . . .

i have survived my mistakes in the past - some of which might have been lethal

... there was an old radio at my grammas (a real - not the spirit of) when a kid i was exploring it ... but it contained the decades of dust , had probably the dried electrolytic capacitors and perhaps more potential fault points . . . so it burst into the fire at one point , gramma run in and poured water on it to set it off ...
... well we both were instantly in a "pool of ~AC" - somehow i managed to fore me to crawl to the wall-plug and pull it off - otherwise it'd have end up with "two flies in a one stroke" condition . . . muhahahahaa . . . \°o­°/ (help,help)

... in India , they tell , the grid maintenance electricians throw out the carbonized cats from the substations , who have crept there for a warm place to sleep ... if you plan a different future ...

my grandpa was a grid maintenance electrician - i'm a long term hobbyist - but even i only touch my hose wiring if it's absolutely unavoidable

get it right - your post is alarming
