Build a quotable request

Start with nominal system voltage, frequency, grounding method, continuous current at the main and each feeder, plus the available fault current at the equipment location. Attach the current one-line revision and identify whether the study value is preliminary or approved. If selective coordination is required, include the upstream and downstream protective devices and the operating range that must be evaluated.

Describe installation conditions separately. State indoor or outdoor location, ambient temperature, altitude, ingress protection or NEMA enclosure need, cable entry direction, available footprint, front and rear access, and the expected maintenance method. These details affect enclosure construction, ventilation, derating, compartmentation and whether fixed or draw-out equipment is practical.

List breaker frames, trip functions, metering, communication protocol, control voltage, interlocks and transfer logic. A request for “65 kA switchgear” is incomplete until the relevant interrupting capacity or SCCR, test basis and assembly location are defined. For a retrofit, provide nameplate photographs, original drawings, existing catalog numbers and the permitted outage window.

Name the destination country and required evidence. UL, IEC, CE and RoHS documents have different scopes, and no mark is assumed to cover an entire product family. The application desk returns a configuration path, assumptions, missing information and document references. Final protection settings, code compliance, arc-flash analysis, installation and energization remain the responsibility of qualified project professionals.

For a repeatable technical check, identify the study revision, equipment location, conductor assumptions and protective-device settings. Record enclosure temperature rather than room temperature where thermal loading matters. If remote operation is requested, state the protocol, ownership boundary and required fail-safe state so another engineer can reproduce the review.
