Adjustable support feet for field leveling Switchgear line up.

[power2engineer]

​

My question is 2 part - for field installation electrical switchgear equipment multiple cubicle line up (Each cubicle typically 30 - 36 or 42 Inches wide + 90 in H X 54 in Depth weighing 1500-2000 lbs each.

If the switch mounting foundation floor is not prefectly levelled does manufacturers allow using shims to adjust so the swithgear line up is on level surface.

Is there anybody switchgear manufacturer offering field adjustable support feet for this application?

Before installing the switchgear you remove the existing flooring, install the mounting rails and pour a new floor around them. The switchgear sits on the steel, not the concrete and if the steel is properly installed there’s nothing to adjust.

I have seen a switch gear lineup jacked up high enough to put a thin layer of levelling concrete underneath.
Some installations have steel angle iron or channels set in the concrete to provide a level support.
Have you considered installing and levelling 2" x 4" channel iron or something similar and then grouting it in to provide a level base?

1. The floor is not expected to be perfectly levelled. It is neither the owner nor the switchgear manufacturer's obligation, but the site installation contractor scope to shim to level and vertically, including bolted up various sections/panels.
Note: The owner does NOT have to pay for the shimming material, including bolt-down bolds and bolts between sections.
1.1 However, if you are the owner and also the site installation contractor, you pay for the shim, bolts etc....NOT the switchboard manufacturer.
2. NO. It is of very small uneven gap which is always expected at site. It is the responsibility /scope of the site installation contractor. The switchgear manufacturer cannot predict the levelling thickness and the location.
