I-TLP luluhlu oluntsonkothileyo lwezixhobo zokukhusela ezenzelwe ukhuseleko lwedatha, unxibelelwano, ukulinganisa kunye nokulawula imigca ngokuchasene nefuthe lokunyuka. Ezi zixhobo zokuzikhusela zicetyiswa ukuba zisetyenziswe kuMgaqo woKhuseleko loMbane kwimida yeLPZ 0_{A (B)} -1 ngokwe-EN 62305. Zonke iintlobo zibonelela ngokhuseleko olusebenzayo lwezixhobo eziqhagamshelwe kwimowudi eqhelekileyo kunye neendlela ezahlukeneyo zokunyuka kweendlela ngokwe-IEC 61643-21. Umthwalo okhoyo ngoku kwimigca ekhuselweyo nganye mna_L <0,1A. Ezi zixhobo ziqulathe iityhubhu zokukhutshwa kwerhasi, uthotho lwempazamo, kunye nokuhamba. Inani lezibini ezikhuselweyo alunakukhethwa (1-2). Ezi zixhobo ziveliswa ngombane ngegama ngaphakathi kuluhlu lwe-6V-170V. Ukukhutshwa okuphezulu ngoku kungu-10kA (8/20). Ekukhuseleni imigca yefowuni, kuyacetyiswa ukuba usebenzise uhlobo olunamandla ombane u-U_N= 170V.
