Ọ dị oke mkpa ịhọrọ ọkwa mgbawa ziri ezi na gburugburu ebe obibi.
Mbụ, ọ dị mkpa ịghọta isi edemede abụọ, dị ka akọwara n'okpuru:
Ụdị ihe mgbawa:
Klas I: Ngwa eletrik maka ogbunigwe kol n'okpuru ala;
Klas II: Igwe ọkụ eletrik maka ndị ọzọ niile mgbawa gburugburu gas ma e wezụga ogbunigwe kol na n'okpuru ala.
Enwere ike kewaa klas II ka ọ bụrụ IIA, IIB, na IIC, ebe enwere ike iji akụrụngwa akara IIB n'okpuru ọnọdụ dabara adaba maka ngwaọrụ IIA; Enwere ike iji IIC n'okpuru ọnọdụ dabara adaba maka IIA na IIB.
Klas III: Ngwa eletrik maka gburugburu uzuzu na-agbawa agbawa na-abụghị ogbunigwe kol.
IIIA: Ofe efe ọkụ; IIIB: Uzuzu na-adịghị mma; IIIC: Uzuzu na-arụ ọrụ.
Ebe na-egbochi mgbawa:
