想請問如果4加侖儲水式電熱水爐,聽說是3000火,如用7條22電線,跳制用20A是否足夠,因我家電熱水爐的電線是二條電線接駁而成,而且開闢制是安裝在浴室內,所以每次煲水電線都會輕微發熱,現請問若水已經煲滾而不關電源沖涼會否有危險,(因為不關電源條電線一直會微熱),如天氣潮濕或浴室有太多水蒸汽會不會影響開闢電源制而發生危險或漏電

7條22電線是舊社會的英制線,現時已多數用公制線了,7條22相等於公制線的2.5cm平方的線,而承受的電流比2.5cm平方的線稍微大些,至於3000W電熱水爐所需的電線載流量即3000W/220V=13.6A左右應無問題,至於熱水爐開關掣是不應該安在浴室內的,而且閣下表示只有兩條電線,缺乏水線是非常危險的。
