yintoni ukuvalelwa ngaphandle kwesekethe

Aisixhobo sokutshixa ngaphandle kwesekethesisixhobo sokhuseleko esisetyenziselwa ukuthintela ukwenziwa kwamandla ngengozi kwesekethe ngexesha lokugcinwa okanye ukulungiswa. Siyinxalenye ebalulekileyo yeenkqubo zokhuseleko lombane kwiindawo zoshishino, zorhwebo kunye neendawo zokuhlala. Injongo yeukutshixelwa ngaphandle kwe-circuit breakerkukuqinisekisa ukuba izixhobo zombane zihlala zingasebenzi kakuhle ngelixa kusenziwa ulungiso okanye ukulungiswa, ngaloo ndlela kukhuselwa abasebenzi kwingozi yokutshayiswa ngumbane okanye ezinye iingozi zombane.

Isixhobo sokutshixa sidla ngokuba sisixhobo esincinci nesiphathekayo esinokuqhotyoshelwa lula kwi-circuit breaker ukuze sithintelwe ukuba singavuleki. Senzelwe ukuba sifakwe ngokukhuselekileyo kwiswitshi ye-circuit breaker, sithintele ukuba sisebenze. Oku kuyayitshixa ngokufanelekileyo i-circuit breaker kwindawo engavalwanga, kuqinisekisa ukuba i-circuit ihlala ingasebenzi de isixhobo sokutshixa sisuswe.

Kukho iintlobo ezahlukeneyo zeukuvalelwa ngaphandle kwe-circuit breakerekhoyo, nganye yenzelwe uhlobo oluthile lwe-circuit breaker kunye nezixhobo zombane. Ezinye izixhobo zokutshixa zenzelwe ukuxhonywa kwi-toggle okanye i-rocker switch eqhelekileyo ye-circuit breaker, ngelixa ezinye izixhobo zokutshixa zenzelwe ukusetyenziswa ne-molded case circuit breakers okanye ezinye izixhobo zombane ezikhethekileyo. Ukongeza, kukho izixhobo zokutshixa ezithwala ii-circuit breakers ezininzi, ezivumela ii-circuits ezininzi ukuba zitshixelwe ngaxeshanye.

Inkqubo yokusebenzisaukutshixelwa ngaphandle kwe-circuit breakerkubandakanya amanyathelo aliqela abalulekileyo ukuqinisekisa ukuphunyezwa ngokufanelekileyo. Okokuqala, abasebenzi abagunyazisiweyo kufuneka bachonge i-circuit breaker ethile ekufuneka itshixwe ngaphandle. Nje ukuba i-circuit breaker ifumaneke, isixhobo sokutshixa sinamatheliswa ngokukhuselekileyo kwiswitshi, nto leyo ethintela ukuba ingavuleki. Kubalulekile ukuqinisekisa ukuba isixhobo sokutshixa sifakelwe ngokuchanekileyo kwaye asinakususwa okanye siphazamiseke lula.

Ukongeza kwizixhobo zokutshixa ngaphandle,ukutshixa/ukuthegaiinkqubo mazisetyenziswe ukubonelela ngesibonakaliso esicacileyo sokuba i-circuit breaker itshixiwe ngaphandle kwaye akufuneki inikwe amandla. Oku kudla ngokubandakanya ukuncamathisela i-lockout tag kwisixhobo esitshixiwe ebonisa isizathu sokutshixiwe, umhla kunye nexesha lokutshixiwe, kunye negama lomntu ogunyazisiweyo owenze ukutshixiwe. Oku kunceda ukwazisa abanye abasebenzi ngesimo se-circuit breaker etshixiwe kwaye kuthintela imizamo engagunyaziswanga yokunika amandla i-circuit.

Ukusetyenziswa kweukuvalelwa ngaphandle kwe-circuit breakerilawulwa yimigaqo nemigangatho yokhuseleko, njengaleyo ibekwe yi-US Occupational Safety and Health Administration (OSHA). Le migaqo ifuna ukuba abaqeshi basebenzise iinkqubo zokutshixa/zokutsalela abasebenzi ngaphandle ukuze bakhusele abasebenzi ekusebenziseni oomatshini okanye izixhobo ngengozi ngexesha lokugcinwa okanye ukulungiswa. Ukungaphumeleli ukuthobela le migaqo kunokubangela izohlwayo ezinzulu kunye nezohlwayo kubaqeshi.

Ukuququmbela,ukutshixelwa ngaphandle kwe-circuit breakerlinyathelo elibalulekileyo lokhuseleko elinceda ekukhuseleni abasebenzi kwiingozi zombane ngexesha lomsebenzi wokulungisa nokulungisa. Ngokuvala iisekethe ngempumelelo, ezi zixhobo zithintela umbane ngengozi kwaye zinciphise umngcipheko wokutshayiswa ngumbane kunye nezinye iingozi. Abaqeshi kunye nabasebenzi kufuneka baqaphele ukubaluleka kokusebenzisa izixhobo zokutshixa iisekethe ngokuhambelana nemigaqo yokhuseleko ukuqinisekisa indawo yokusebenza ekhuselekileyo.
