U: Ngingakukhetha kanjani isilinganiso samanje esifanele sefuse engu-5x20mm kusekethe yami?
A: Isilinganiso samanje sefuse kufanele sikhethwe sibe ngaphezu kwamanje ojwayelekile womthwalo ogcwele wesekethe kodwa ngaphansi kwamanje okungabangela umonakalo kubaqondisi noma imishini evikelwe. Isiqondiso esivamile ukukhetha isilinganiso sefuse esingu-125% kuya ku-150% wamanje ojwayelekile womthwalo ogcwele. Kumasekethe anama-motor noma ama-transformer, bheka ugesi ongenayo ngesikhathi sokuqalisa ukuqinisekisa ukuthi ifuse ayivuthi ngesikhathi sokusebenza okuvamile. Uma ungabaza, bheka iziqondiso zokuxhumanisa ukuvikelwa komenzi wemishini noma uthintane nonjiniyela kagesi ofanelekayo.

U: Ngingahlola kanjani ukuthi i-fuse yekhatriji engu-5x20mm isasebenza kahle?
A: I-cartridge fuse ingahlolwa nge-multimeter esethwe ekulinganisweni kokuqhubeka noma kokumelana. I-fuse enhle izobonisa ukufundwa kokumelana okuphansi (ngokuvamile ngaphansi kwe-1 ohm ye-fuse engu-5x20mm ekushiseni kwegumbi). I-fuse evulekile izobonisa ukumelana okungenamkhawulo (akukho ukuqhubeka). Qaphela ukuthi ezinye izinhlobo ze-fuse—ikakhulukazi ama-fuse asebenza ngokushesha kakhulu anezici ezincane kakhulu—zingabonisa ukumelana okuphezulu kancane ngisho noma zilungile, kodwa kufanele ziqhubeke nokubonisa ukuqhubeka. I-fuse evulekile ngokuqinisekile ihlala yehluleka futhi kufanele ishintshwe.
