1.Strictly kuraira vashandi kuti vaone zvikamu zve weld maererano nemirairo yekushanda.Mushure mese batch components kugadzirisa, zvinofanirwa kutumirwa kune vanoongorora kuti vaongororwe pamberi peinotevera maitiro ekushanda.Mutungamiriri wekuongorora ane basa rekuongorora kwekupedzisira uye kurekodha zvabuda
2.Kuitira kuve nechokwadi chemhando, ese maRCDs uye RCBO anofanirwa kunge achiyedza yavo yekufamba ikozvino uye yekuzorora nguva maererano neICE61009-1 uye ICE61008-1.
3.Tinonyatso edza maitiro ekushanda kwedunhu rinoputika.Mabreaker ese anofanirwa kupasa hunhu hwenguva pfupi-pfupi tese uye yenguva refu yekunonoka maitiro bvunzo.
Iyo pfupi-nguva yekunonoka hunhu inopa dziviriro kubva kupfupi-dunhu kana kukanganisa mamiriro.
Iyo yenguva yakareba yekunonoka hunhu inopa kudzivirira kwekuremerwa.
Kunonoka kwenguva refu (tr) inoisa urefu hwenguva iyo muparadzi wedunhu achatakura kuremerwa kwakasimba asati atsika.Mabhendi ekunonoka akanyorwa mumasekonzi epamusoro pazvino panguva katanhatu iyo ampere rating.Kunonoka kwenguva refu inguva inverse hunhu pakuti nguva yekufamba inodzikira sezvo ikozvino inowedzera.
4.High Voltage Test paCircuit Breaker uye Isolators inotarisirwa kuongorora maitiro ekuvaka uye ekushanda, uye maitiro emagetsi edunhu Izvo zvinoshandura kana kuputika kunofanira kukanganisa kana kugadzira.
5.Kuchembera bvunzo yakanziwo simba bvunzo uye bvunzo yehupenyu, kuve nechokwadi chekuti zvigadzirwa zvinogona kushanda zvakajairika musimba repamusoro mamiriro panguva yakatarwa.Ese edu emagetsi mhando RCBOs anofanirwa kupasa bvunzo yekuchembera kuti ave nechokwadi chekuvimbika kwekushandisa.
