How do we know what the instructions state for this transformer?
I have installed a few transformers that only allow upper 1/3 installation of conductors.
I do not agree with renosteinke that
the panel seems to be part of the same installation as the transformer, and thus allowed
The front edge of the switch would have to be within 6" of the front of the transformer.
110.26(A)(3) Height of Working Space. The work space shall be clear and extend from the grade, floor, or platform to the height required by 110.26(E). Within the height requirements of this section, other equipment that is associated with the electrical installation and is located above or below the electrical equipment shall be permitted to extend not more than 150 mm (6 in.) beyond the front of the electrical equipment.
That is of course if the disconnect is likely to require examination, adjustment, servicing, or maintenance while energized.
Perhaps the company policy here is to shut of the power to the disconnect before servicing.
A strict reading of the OSHA requirements would suggest shutting down the disconnect would be easer than working in the proper PPE.
