Hint: Out of sight. Out of mind. Out of reach.
With the storage shelves and all the sale items impeding access to the panelboard and all the circuit breakers inside of it, hopefully this shop owner never needs to access those circuit breakers in an emergency. Section 240.24(A) requires overcurrent devices to be readily accessible. That is certainly questionable for this installation. Section 240.24(D) prohibits overcurrent devices from being installed near easily ignitable materials. There is clothing hanging right in front of this panelboard! Performing maintenance, inspections, and troubleshooting in this energized equipment could also pose some risks too. Section 110.26(A) requires clear space to be maintained in front of this equipment to provide a safe working area for service personnel working on this energized equipment. Unfortunately, violations of these working space requirements are an all-too-common problem that I regularly see.
