Is condensation build-up ``normal`` on the inside of a NEMA 3R panelboard NQ?

Product Line:
PTFDS - FD Enclosure Systems

Environment:
Panelboards sold and supported in the USA.

Cause:
Concern over condensation forming inside panelboard enclosures.

Resolution:
Yes, depending on the amount of moisture in the air. The NEMA 3R enclosure in not air-tight and allows outside air to pass throughout the enclosure. As the temperature rises and falls condensation can build up on the inside and out side of the enclosure. A weep hole is provided for drainage of any moisture build-up.
