Where a 2500 kVA pad-mount transformer fits

Three-phase pad-mounts at 2500 kVA are typically used for large commercial buildings, campuses, industrial plants, data centers, and EV charging sites. A 480Y/277 secondary suits motors, HVAC equipment, and 277 V lighting, and is the usual choice for larger commercial and industrial services.

Full-load secondary current is the first sizing check: at 480Y/277 a 2500 kVA 3-phase unit draws about 3,007 A at full load. The secondary conductors, main breaker, and switchboard or panel have to be rated for that current.

This rating comes with both delta and grounded-wye primaries: 12470 Delta connects to a three-wire delta feeder, while 12470Y/7200 expects a grounded-wye feeder with a neutral, so match the primary to the utility or site system. One configuration lists a multi-voltage delta primary from 11500 V to 14400 V, useful when the site primary voltage is not fixed yet; confirm on the nameplate how each voltage is selected.

If the calculated load sits close to 2500 kVA, compare the 2000 kVA and 5000 kVA pages under Nearby sizes before choosing a rating.

What to confirm before buying a 2500 kVA pad-mount transformer

Primary voltage and connection against the utility or site feeder. Rows here list 12470 Delta, 12470Y/7200, or 14400x13800x13200x12870x12470x12000x11500 Delta.
Secondary voltage against the service you are building. Rows here list 480Y/277.
Taps (2x2-1/2% ANBN or No Taps) and bushing layout (Dead/Loop (Pad)). A loop-feed unit has two sets of primary bushings and a radial-feed unit has one.
Percent impedance from the nameplate, which sets the available fault current at the secondary and has to suit downstream equipment ratings.
Insulating fluid type, because site and fire rules can limit mineral oil close to buildings.
The factory test report for a new unit, and the post-refurbishment test results for a refurbished unit, such as insulation resistance, turns ratio, and oil tests.
Pad dimensions, shipping weight, and offloading. With FOB origin shipping, the buyer takes responsibility for the unit once it leaves the origin.

Why buy surplus vs. new

A new pad-mount transformer is built to the voltage and accessory spec on the order, so the lead time is whatever the factory quotes. Cleared surplus in the table already exists, and the lead time to use is the one printed on the row.

On this page, availability is In stock and lead time is Ships from stock. Gripp does not add a ship date the lot does not state. Shipping is FOB origin.

Public and private buyers can request an offer for a row. That signup is how Gripp matches the spec. Prices are not listed.
