Question:
Why did Square D manufacture a I-Line panel with no door or cover over the breakers? Catalog # HCWM 12-3174740U0 1200 AMP, SERIES E1, 480 Volt, 3 PH, 3 Wire I can send pictures since this is an older panel board. There is a CAT 2 PPE required label on the front. 96 inch Flash Hazard Boundary

Answer:
Hey Kris thanks for your question. In general panelboards must be Dead Front, based on that definition in Article 100, as stated in 408.38. A cover or door is not necessary for the circuit breaker or switch handles, if the cabinet meets that requirement. Several panelboard manufacturers have listed products like that, possibly because it is less expensive without the extra cover or door.
