2-2 Trane Liqui-Flo Addendum
Table 2.1 – Power and Enclosure Ratings
2.2 Enclosure Rating
The Trane cabinet has a NEMA 1 enclosure rating:
• NEMA 1: Vented. Intended for general-purpose indoor applications.
NEMA 1 enclosures are to be located in a clean and dry environment that is away
from oil, coolant, or other airborne contaminants.
