What is a transformer pad?
A transformer pad is a concrete slab that supports a pad-mounted electrical transformer, usually outdoors at grade. It gives the transformer a level, durable base and includes openings or sleeves so cables can enter from below. The utility or the electrical engineer usually sets the size, thickness and conduit window, and requirements differ from one utility to the next. A housekeeping pad is a smaller interior pad that lifts equipment off the floor, and an elevated equipment pad sits on structure rather than on grade.

Questions
What is a concrete transformer pad?
It is the concrete base a pad-mounted transformer sits on. The pad is placed level on compacted base material, with conduit stubs or a cable window cast in so underground feeders can rise into the transformer. Many utilities publish their own pad standards, so the contractor builds to the serving utility's drawing for that site.
Should a transformer pad be cast in place or precast?
Both are common. Cast-in-place pads are formed and poured on site, which suits custom sizes and conduit layouts. Precast pads arrive ready to set and can save time where the utility accepts them. The serving utility often decides which is allowed, and the choice changes the scope of formwork, concrete and setting labor.
