你祈禱你唔好時運低啦。
當你 D 電器裏面有元件失常時，
一係就電你一鑊金嘅，一係就火燭。

好心你唔知就唔好亂嗡啦。
唔知個 D 比你嚇死。
知個 D 就比你笑死。
其實你知唔知日，美製電器如用兩腳插的必有【回】字標記。
無【回】字標記那些全部是三腳插，裝回地極架。
你知唔知個【回】字標記係代表D乜架？

依據定義 Double-insulated 雙重絕緣產品是指產品為防止使用者發生電擊危險所採用的絕緣措施，如 Double Insulation 或 Reinforced Insulation，且不以接地來防止電擊危險，因為產品沒有接地連接，所以電源線 (Power Supply Cord) 或電源線組 (Power Supply Cord Set) 的插頭 (plug) 或 Connector 就沒有接地 pin。
那沒有接 pin 的插頭 (plug) 結構如何?
(a) 1-15P for 125 V, 15 A or less. 如下圖:
(b) 2-15P for 250 V, 15 A or less. 如下圖.
Double Insulated
呢個係代表電器屬於 CLASS II, 即係有雙重絕緣安全設計 (Double Insulated, 可以唔需要有地線連接情況下, 喺突然/意外間電壓過大嘅情況下都唔會傳到電器表面.
Double Insulated Symbol found on all class 2 products
Double insulated or class 2 electrical appliances are products that have been designed in a way so as not to require a safety connection to electrical earth (These products must NOT have a safety connection to Earth).
These products are required to prevent any failure from resulting in dangerous voltage levels becoming exposed causing a shock etc. This must be done without the aid of an earthed metal casing. Ways of achieving this include double layers of insulating material or reinforced insulation protecting any live parts of the fitting.
There are also strict requirements relating to the maximum insulation resistance and leakage to any functional earth or signal connections of such appliances. Products of this type are required to be labelled "Class II", "double insulated" or bear the double insulation symbol (the symbol displayed above) Follow some of the links below to view / purchase some examples of these products
