Mida peab tähele panema elektrijuhtmete puhul?

Juhime teie tähelepanu sellele, et kõiki elektriseadmete juhtmeid ja pikendusjuhtmeid tuleb regulaarselt kontrollida. Ohumärgid on rebenenud isolatsioon, muljumised, ebatasasused isolatsioonis ja põletusjäljed. Elektrijuhtmeid ei tohi peita vaiba alla, sest see suurendab juhtme muljumise või isolatsiooni rebenemise ohtu ning nõnda ei ole võimalik ohumärke õigeaegselt tähele panna. Samuti suureneb nii ka juhtme ülekuumenemise risk. Lisaks tuleb kindlasti jälgida, et pikendusjuhtme taha ei oleks ühendatud võimsaid elektriseadmeid ning kokku ei tohi omavahel ühendada mitu pikendusjuhet.

Paluks mulle kui füüsikule seletada ära füüsikalised põhjused, miks ei tohi omavahel ühendada mitu pikendusjuhet?

Sellepärast, et kui füüsikatunnist puudunule see lubada, siis ühendab ta kogu majapidamise pikendusjuhtme külge ja tulekahju on ruttu tulemas, sest ei arvesta, et pikendusel on kirjas maksimaalne number ampreid.

Enamikel pikendustel kipub selleks maksimuks olema peal kirjas 16A mis on juhtumise ka maksimum mida tavaliselt pistikupesast on võimalik saada.
Ei tohiks olla mingit võimalust lasta pikendusjuhtmeid kärssama, enne peaks kaitse rakenduma.

Päästeamet/tarbijakaitse võiks tegeleda nõuetele mittevastavate pikendusjuhtmete müügilt eemaldamisega. Kurvakstegevalt palju on selliseid juhtmeid müügil näha mis omavad 16A märgist, aga ilmselgelt sellise voolu juures põlevad. Ilmselt piisab lihtsast koormustesist/katsest ja füüsikalaboreid polegi vaja.

lisaks mainiks, et kui kasutate pikka pikendusjuhet, mis rullil, siis enne võimsa seadme ühendamist oleks soovitav juhe rullilt suuremas osas lahti kerida, muidu läheb kuumaks. kah füüsika.
