Well, unfortunately we can’t blame the plumbers for this infraction. We can only blame the electrician for installing this transformer directly in the way of this panelboard. Not only did he make it more difficult for him to work in this panelboard, but he also created a Code violation by locating it here.
Access and working space for electrical equipment must be provided in accordance with Sec. 110.26. Working space for this 480V panelboard must be maintained in accordance with (A)(1), (A)(2), and (A)(3) of this section. The minimum working space depth in front of this panelboard is required to be 3 ft. The minimum width is required to be 30 in. This space must be clear and extend from the floor to a minimum height of 6 ½ ft. The only encroachment permitted in this space is with equipment associated with the panelboard, which is located above or below the panelboard. The transformer fits this description; however, the encroachment is only permitted to be 6 in. This transformer extends much more than that distance into the working space.
Reaching over this transformer while working in an energized panelboard will greatly increase the risk of an accident.
