What to include in an equipment purchase inquiry
Send the controlling specification and one-line, then fill any open items in this comparison. Mark unknown information as a question rather than assuming two quotations include the same scope.
| Check | Transformer | Switchgear or switchboard |
|---|---|---|
| Duty and identity | Listing ID or proposed manufacturer/model; GSU, step-down or distribution duty; quantity. | New build or identified lineup; equipment type; main/tie/feeder schedule; quantity. |
| Electrical ratings | All cooling-stage MVA/kVA, winding voltages, frequency, connections, taps, impedance and insulation. | Voltage, continuous current up to the specified rating, fault rating, breaker duty and control voltage. |
| Interfaces | Terminations, neutral, grounding, footprint, oil/fluid, cooling equipment and controls. | Transformer/generator interface, busway/cable entry, enclosure, interlocks, protection and controls. |
| Condition and records | Energization history, preservation, repair/rebuild scope, nameplate, drawings and matching tests. | Lineup and component identities, condition, breaker/relay schedules, drawings and tests. |
| Included scope | Bushings, radiators, fans, accessories, loose-shipped parts, preparation and loading. | Mains, tie, feeders, relays, metering, controls, auxiliaries and excluded equipment. |
| Commercial terms | Price basis, inspection, allocation, warranty provider/start date, freight and delivery milestone. | Price basis, approval drawings, build/release schedule, warranty, freight and installation boundaries. |
Compare shipment, delivery and commissioning separately
Ask which milestone each offered date describes: factory completion, seller release, ready for shipment, arrival at port, arrival at site or commissioning. Confirm inspection, packing, loading, freight, receiving and installation responsibilities. An unused description or historical test report does not establish present readiness or an active OEM warranty.

Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Does this checklist replace the project engineering specification?
No. It helps organize procurement information. The responsible engineers and utility approve equipment suitability, applicable standards and the final project requirements.
