Where a 300 kVA pad-mount transformer fits

Three-phase pad-mounts at 300 kVA are typically used for mid-size commercial buildings, schools, multifamily buildings, and light industrial plants. A 208Y/120 secondary suits buildings where most loads are 120 V receptacles, lighting, and small equipment. A 480Y/277 secondary suits motors, HVAC equipment, and 277 V lighting, and is the usual choice for larger commercial and industrial services. A 4160Y/2400 secondary feeds medium-voltage motors or a downstream distribution system rather than a building panel.

Full-load secondary current is the first sizing check: at 208Y/120 a 300 kVA 3-phase unit draws about 833 A at full load; at 480Y/277 a 300 kVA 3-phase unit draws about 361 A at full load; at 4160Y/2400 a 300 kVA 3-phase unit draws about 42 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.

If the calculated load sits close to 300 kVA, compare the 225 kVA and 500 kVA pages under Nearby sizes before choosing a rating.

What to confirm before buying a 300 kVA pad-mount transformer

Primary voltage and connection against the utility or site feeder. Rows here list 12470 Delta or 12470Y/7200.
Secondary voltage against the service you are building. Rows here list 208Y/120, 480Y/277, or 4160Y/2400.
Taps (4x2-1/2% BN, 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.
