1. Ukusika amandla ngokushesha:
Ngaphambi kokubhekana nokungena kwamanzi kwintambo, kuyadingeka ukusika ngokushesha ukuhanjiswa kwamandla ukuze kuqinisekiswe ukuphepha kwabasebenzi.
II. Bheka imbangela yokungena kwamanzi
Hlola ngokucophelela izimbangela zokungena kwamanzi kukhebula, njengokubekwa kahle okumpofu ekhanda lentambo, ukuqhekeka kokuqothuka kwangaphandle ngesikhathi sokubeka kahle, njll.
III. Ukususwa komswakama
Sebenzisa indwangu eyomile noma izinto zokungena ukuze ususe umswakama omningi ngangokunokwenzeka kusuka ebusweni bekhebula.
Kumanzi aqoqiwe ngaphakathi kwekhebula, imishini yokumisa ochwepheshe efana nokomisa okushisayo kwe-nitrogen noma ama-desicstants angasetshenziswa.
IV. Bheka isimo sekhebula
Sebenzisa amathuluzi afana ne-multimeter ukubheka ukuthi ngabe ukusebenza kwe-insulation yekhebula kunqabile yini.
Uma ikhebula linokusebenza okuhle kokufakelwa, lingaqhubeka lisetshenziswe. Uma ukusebenza kokufakwa kwe-insulation kuncipha, kudingeka ukwelashwa okwengeziwe.
