Electrical Estimator (UL 508A) - 5K Power

UL 508A / Custom Electrical Equipment 

• Review RFQs, specifications, one-line diagrams, schematics, panel schedules, and drawings.

• Develop detailed estimates and accurate Bills of Material (BOMs) for custom panels and power distribution equipment.

• Determine material, fabrication, assembly, wiring, testing, engineering, and production labor requirements.

• Obtain vendor pricing, evaluate lead times, and identify cost-effective component alternatives while maintaining ratings.

• Generate complete project pricing for management review and customer quotation.

• Maintain estimating history and continuously improve standards based on actual production costs.

• Apply UL 508A standards during estimating and design, including component selection and application.

• Evaluate voltage, amperage, SCCR, interrupting ratings, conductor sizing, overcurrent protection, and disconnecting means.

• Utilize knowledge of breakers, disconnects, contactors, starters, relays, power supplies, transformers, terminal blocks, VFDs, and PLCs.

• Identify UL-compliant component substitutions to resolve lead time or availability issues.

• Collaborate with engineering and production to ensure designs are efficient and fully compliant.

• Assist with preliminary panel layouts, equipment configurations, and sizing appropriate NEMA enclosures.

• Evaluate space requirements and resolve design conflicts or missing details prior to production.

• Develop conceptual arrangements for incomplete customer designs and support design-build opportunities.

• Request and evaluate component manufacturer quotations.

• Track component pricing, availability, and lead times across major electrical manufacturers.

• Implement alternate sourcing strategies when specified items impact schedule or cost.
