Kutsika kwapansi ndi mphamvu yomwe imafika pansi kudzera m'njira yosakonzekera. Pali magulu awiri: kutayikira mwangozi chifukwa cha kutchinjiriza kapena kulephera kwa zida ndi kutayikira mwadala chifukwa cha momwe zida zidapangidwira. Kutayikira kwa "Design" kumatha kuwoneka kwachilendo, koma nthawi zina kumakhala kosapeweka - mwachitsanzo, zida za IT nthawi zambiri zimatulutsa kutayikira ngakhale zikugwira ntchito bwino.
Mosasamala kanthu za kumene kutayikirako, kuyenera kupewedwa kuti zisawononge magetsi. Izi nthawi zambiri zimachitika pogwiritsa ntchito RCD (chipangizo choteteza kutayikira) kapena RCBO (chopumira chotchinga chokhala ndi chitetezo chopitilira muyeso). Iwo amayesa panopa mu kondakitala mzere ndi kuyerekeza ndi panopa kondakitala ndale. Ngati kusiyanaku kupitilira mlingo wa mA wa RCD kapena RCBO, idzayenda.
Nthawi zambiri, kutayikirako kumagwira ntchito monga momwe amayembekezeredwa, koma nthawi zina RCD kapena RCBO imapitilira kuyenda popanda chifukwa-uwu ndi "ulendo wokhumudwitsa". Njira yabwino yothetsera vutoli ndi kugwiritsa ntchito mita yochepetsera kutayikira, monga Megger DCM305E. Izi zimatchingidwa mozungulira waya ndi kondakitala wosalowerera (koma osati woteteza!), Ndipo imayesa kutayikira kwapansi.
Kuti mudziwe kuti ndi dera liti lomwe layambitsa ulendo wabodza, zimitsani ma MCB onse mugawo lowonongera mphamvu ndikuyika chotchingira chotsikira pansi mozungulira chingwe chamagetsi. Yatsani dera lililonse motsatana. Ngati chiwongola dzanja chikuwonjezeka kwambiri, ndiye kuti izi zitha kukhala zovuta. Chotsatira ndicho kudziwa ngati kutayikirako kudachitika mwadala. Ngati ndi choncho, mtundu wina wa kufalikira kwa katundu kapena kulekanitsa dera ndikofunikira. Ngati ndi kudontha kwangozi—chotsatira cha kulephera—kulepherako kuyenera kupezedwa ndi kukonzedwa.
Musaiwale kuti vuto likhoza kukhala RCD yolakwika kapena RCBO. Kuti muwone, chitani mayeso a ramp RCD. Pankhani ya chipangizo cha 30 mA-chiwerengero chofala kwambiri - chiyenera kuyenda pakati pa 24 ndi 28 mA. Ngati ikuyenda ndi mphamvu yocheperako, ingafunike kusinthidwa.
