:pmuka: nak tanya pada pakar dlm electrical apa perbezaan penggunaan fius ac dengan dc....contoh saya ada fius 30A AC 500v boleh kah saya guna pada peralatan yg menggunakan fius 30A DC 400v...saiz sama,ampere sama, volt lain saja ...?:lebai:

nie pakai kat mana nihh..
tak pernah tengok pun ada fuse DC..rsanye sama jerr..AC ke DC
tapi kalau boleh tahan sampai 30 amp tu kiara ok lerr..
volt tu untuk max 500V input...klau rate rendah senang blow..tu jerr
fuse tu buleh guna...
jgn amik rate amp lebih dari 30amp dan 600V sudahhh....

AC fuse dlm DC circuit: bila spike, fuse tak blow, barang rosak.
DC fuse dlm AC circuit: fuse terus blow.

Kalau anda tersentuh punca arus AC, anda akan tertolak menjauhi punca arus elektrik tu.

Kalau tersentuh punca arus DC, anda akan tertarik dan melekat pada punca arus. Punca utama orang mati kena karan, sbb terkena arus DC :bgrin:

tak de lah. yg selalu dlm tv tercampak jauh2 tu pakai wire dia tarik.

bila ada sensation & kita boleh control muscle (DC 62mA, AC  9mA), kita akan tarik tangan kita. bukan tertolak.

bila kita dah tak boleh control muscle (DC 76 mA, AC 16 mA), tu yg melekat. tapi bila muscle tu dah abis guna ATP (tenaga) dia releks balik (biasanya dah mati atau pengsan), akan lepas juga walaupun tak off lagi.

pernah nampak org betul2 tercampak atau org melekat pas tu kena off baru boleh tarik in real life?

All fuse or circuit breaker can be used in AC or DC circuit,but the rated voltage & current wont be the same. You need to check with the
manufacturer
