PSE
I-1.Isiqinisekiso sokhuseleko: I-socket kufuneka idlulise isatifikethi se-arhente yokhuseleko eyaziwayo, njenge-UL, ETL , CE, UKCA, PSE, CE njl, ukuqinisekisa ukuba idlula uvavanyo lokhuseleko nokuthembeka.
I-2.Ukwakhiwa komgangatho ophezulu: Umzimba oyintloko we-switchboard kufuneka wenziwe ngezinto eziphezulu, ezifana neplastiki enzima enzima.Amacandelo angaphakathi kufuneka enziwe ngezinto ezizinzileyo ezifana neengcingo zobhedu ukuqinisekisa ukuhanjiswa kwamandla okukhuselekileyo nokuthembekileyo.
I-3.Ukukhuselwa kwe-Surge: Imichilo yamandla kufuneka ibe nokukhusela kwi-surge eyakhelwe ngaphakathi ukukhusela izixhobo ezixhunyiwe kwi-surges zombane ezinokubangela umonakalo okanye ukungasebenzi.
4.Imilinganiselo yombane echanekileyo: Iireyithingi zombane kwii-switchboards kufuneka zichaneke kwaye ziphawulwe ngokucacileyo ukuthintela ukugcwala kunye nokunciphisa umngcipheko wokutsha kombane.
I-5.Isiseko esifanelekileyo: I-switchboard kufuneka ibe nenkqubo efanelekileyo yokunciphisa umngcipheko wokutshatyalaliswa kombane kunye nokuqinisekisa umsebenzi oqhelekileyo wombane.
I-6.Ukukhuselwa kwe-Overload: I-switchboard kufuneka ibe nokukhuselwa komthwalo ogqithiseleyo ukukhusela ukushisa kunye nomlilo wombane obangelwa ngumthwalo ogqithiseleyo.
I-7.Umgangatho wocingo: Intambo edibanisa ikhebula kunye nesokhethi kufuneka yenziwe ngezinto eziphezulu, kwaye ubude bufanele buguquguquke ngokwaneleyo ukuze bubeke.
