Shenhai e fakamoʻoni fakaʻauha
Faʻahinga ʻo e fakamoʻoni fakaʻauha:
ʻOku fakafaʻahinga ʻa e meʻangaue ki hono fakamoʻoniʻi ʻo e CT4 ʻo hange ko Exd IIC T4. ʻOku ʻai ʻa e meʻangaue BT4 ki he fakamoʻoni ʻo e fakaʻauha ko Exd IIB T4, ʻa ia ko ha faʻahinga fakamoʻoni maʻulalo ange ia ʻi he meʻangaue CT4.

Kaunga Ki Aí:
ʻOku maʻu ʻe CT ʻa e ngaahi meʻa kehekehe ʻoku kaunga ki ai.
ʻAtakai ʻo e kasa:
CT is an explosion-proof rating for acetylene and fakapaaki ʻo e ʻo e tuʻunga. If there are gases like acetylene or hydrogen in the environment, CT-rated explosion-proof equipment is required. BT-rated equipment is not suitable for acetylene environments and is only considered a moderate tuʻunga ʻo e fakamoʻoni fakaʻauha.
