Air, kalau dalam kuantiti yang banyak dah boleh jadi penebat. Cuba check earthing system. __________________ Henry Ford Coming together is a beginning. Keeping together is progress.

ye kalau di elektrikal workshop air juga digunakan sebagai test load bank.
tunggu je lah sikit lagi akan chakebabun lah nanti.

Pasal tak terik banyak kena tgk.
Bagaimana MCCB tu function dan jenis?

Themal operating.
Overload and shortcircuit

ST operating.
selari O/C relay x hantar signal x trip ah dia.

Check Grounding and E/F system walau pun air tu penebat tetapi earth leaking dah ada.

Kalau air bnyak bole jadi penebat.. Kalau air sikit pula macam mana? Adakah ia selamat jikalau orang sentuh air yang sedikit? __________________ "Great hopes make great men." Thomas Fuller
