What should companies look for when hiring an electrical contractor for warehouse automation or robotics systems?
Warehouse automation — including automated storage and retrieval systems (AS/RS), conveyor networks, autonomous mobile robots (AMRs), and goods-to-person picking systems — has demanding electrical requirements that go well beyond standard commercial wiring. Here's what to look for when evaluating electrical contractors for automation projects.
Experience with automation-specific electrical work
Automation warehouse electrical work involves: 480V three-phase power distribution to automation equipment; motor control centers (MCCs) for conveyor and sortation systems; variable-frequency drives (VFDs) for motor speed control; charging infrastructure for AMR fleets; PLC and controls wiring for automation system integration; industrial Ethernet networking for automation controls; cable tray and conduit infrastructure at scale; and safety systems including E-stops, light curtains, and restricted-access interlocks. Verify that your candidate has completed similar projects by asking for references and visiting active sites.
Coordination with automation system vendors
Automation system vendors (Dematic, Honeywell Intelligrated, Bastian Solutions, Swisslog, etc.) have specific electrical installation requirements documented in their equipment manuals. Your electrical contractor must be willing and able to work directly with the automation vendor's installation team, follow vendor-specific wiring requirements, and participate in the system's commissioning and testing. Ask your automation vendor whether they have preferred electrical contractors — some do.
Safety certifications and program compliance
Warehouse automation sites typically require that contractor employees hold OSHA 30 certification, complete site-specific safety orientations, and comply with the facility's lockout/tagout (LOTO) and arc flash programs. For sites in active operation, the contractor must be comfortable working around ongoing operations, following traffic management procedures, and maintaining work area cleanliness and organization. Vetting these capabilities up front prevents disruption during installation.
Commissioning support and as-built documentation
A qualified automation electrical contractor will support the full commissioning process — not just install and leave. This includes: power-up sequencing coordination with the automation vendor; troubleshooting during initial equipment testing; correction of any wiring issues discovered during commissioning; and delivery of complete as-built electrical drawings at project close. Incomplete or inaccurate as-builts are a persistent problem in warehouse automation projects — require them contractually.
