Hint: A not-so-weatherproof outdoor panel
This panelboard enclosure is installed in an outdoor wet location, yet the enclosure is designed only for use in dry locations. It is not a weatherproof enclosure as required by Sec. 312.2. Section 312.2 also requires surface mounted cabinets in wet locations to be placed or equipped to prevent water or moisture from entering and accumulating in the enclosure. This metal cabinet is also required to be installed with at least 1/4-in. of air space between it and the mounting surface. Table 110.28 provides information for selecting the correct type of enclosures for specific locations. Another problem here is the incorrect use of a LFMC connector for connecting ENT to the cabinet. This is a violation of Sec. 110.3(B) and Sec. 300.15 as this connector is not designed and listed for use with this wiring method. Lastly, ENT should not be used in this sun-drenched location unless it is identified as being sunlight resistant as specified in Sec. 362.12(7). Current Transformer Cabinets
