Enye yezinzuzo eziyinhloko ze-120A yezitolo eziphezulu zamanje yikhono lokusingatha imisinga ephezulu kalula. Ilinganiselwe kufika ku-120A, ihlinzeka ngamandla angaguquki, athembekile ezindaweni ezidinga kakhulu zezimboni. Lokhu kunciphisa kakhulu ingcuphe yokunqamuka kukagesi nesikhathi sokuncipha esihlobene, okuvumela amabhizinisi ukuthi agcine amazinga okukhiqiza futhi anciphise noma yikuphi ukulahlekelwa okungaba khona. Ukwengeza, i-120A high-current outlet yakhelwe kalula ukuyifaka nokugcinwa engqondweni. Ukuxhumeka kokulinganisa ukucindezela kuvumela inqubo yokufaka esheshayo nelula, yonga isikhathi nomzamo. Ukwengeza, ukwakhiwa okuqinile kwesokhethi kuqinisekisa impilo ende yesevisi, kunciphisa isidingo sokushintshwa nokugcinwa njalo.
