    Confirm loads, clearances, shutdown constraints, and AHJ requirements. Photos/drawings collected so estimates match reality.

  2. Estimate & Plan
    Itemized quote, utility & permit plan, submittals, and schedule (after-hours/weekend changeovers when needed).

  3. Installation & Safety
    Licensed crews execute feeders, gear, lighting/controls, devices. Daily housekeeping and NFPA 70E LOTO practices.

  4. Testing, Inspection & Close-Out
    Torque checks, IR scans (when scoped), labeled panels, as-builts, photos, test results, and inspection sign-off. Optional PM service.


Safety & Compliance You Can Audit

  • NFPA 70E energized work permits, PPE categories, LOTO procedures.

  • Arc-flash short-circuit/coordination studies, device settings, and field labels.

  • Close-out packet: as-builts, photos, panel schedules, torque/IR logs.


Cost Drivers & Typical Timelines

What affects price/time:

  • Capacity & voltage: 120/208 vs 277/480V, available fault current, service size.

  • Gear lead times: switchgear, ATS, transformers, networked controls.

  • Shut-down windows: after-hours/weekend premiums to avoid downtime.

  • Site conditions: ceiling type/height, conduit pathways, coring/trenching, roof penetrations.

  • AHJ & utility: permit review and meter/set dates.

Rough expectations (typical):

  • Small TI circuit adds: 1–3 days on site.

  • Panelboard change-out: 1 weekend with pre-fab.

  • Service upgrade with new switchboard: 1–3 weekends (utility schedule dependent).

  • Lighting retrofit (50–200 fixtures): 1–5 nights with lift access.


How to Pick the Right Commercial Electrical Contractor

  • Quote clarity: scope boundaries, alternates, exclusions, schedule plan.

Frequently Asked Questions


      Do you work on 277/480V distribution?

      • Yes—service equipment, switchgear/switchboards, feeders, and transformers are core scopes.

      Can you quote without a site walk?

      • With clear drawings and photos, yes. We still recommend a short site visit to lock down access, clearances, and shutdown constraints.

      Will you work after hours to avoid downtime?

      • Absolutely—weeknight or weekend changeovers are common for service gear and large TI.

      Do you handle permits and the utility?

      • Yes. We prepare submittals, pull permits, and coordinate with the utility for new service, meter sets, and cutovers.

      What do I get at close-out?

      • As-builts, labeled panel schedules, torque logs, IR images (if scoped), test results, photo documentation, and a PM checklist.

      Where do you respond for emergencies?

      • Greater El Paso and Las Cruces. We hold limited rapid-response slots weekly.
