Qualified for NEVI-Funded EV Infrastructure
The National Electric Vehicle Infrastructure (NEVI) Formula Program provides federal funding to states to build a reliable, interconnected network of public EV charging stations along designated highway corridors. EVITP certification meets a required installer training standard for projects funded through this program.
Permitting, Compliance & Inspections
Permitting requirements for commercial EV charging infrastructure vary significantly across Washington State jurisdictions. LeMaster Electric works directly with Authorities Having Jurisdiction (AHJs) and electrical inspectors to navigate regulatory requirements, facilitate electrical plan reviews, and identify alternative code-compliant permitting pathways when extended review timelines threaten project schedules.
Permitting and inspection coordination includes:
- Commercial EV charging electrical permitting
- Electrical plan review facilitation when required
- AHJ coordination and alternative compliant permitting pathways
- Underground, rough-in, and final electrical inspections
- Inspection scheduling and resolution of compliance issues
Proactive coordination with regulatory authorities helps minimize approval delays, streamline inspections, and keep commercial EV charging projects moving toward energization.
Field Coordination
Commercial EV charging projects require coordination across multiple trade disciplines, utility providers, and active facilities. From phased construction and site lighting upgrades to complex utility shutdowns and service interruptions, each installation presents unique challenges requiring careful planning and execution.
Field coordination includes:
- Construction phasing, scheduling, and sequencing
- Utility coordination, planned outages, and service cutovers
- Collaboration with general contractors, EPCs, civil contractors, and utility providers
- Site lighting, electrical service upgrades, and supporting infrastructure
- Underground utility conflicts and evolving site conditions
- Electrical inspections, equipment deliveries, and energization scheduling
Whether maintaining access to an active commercial property, coordinating a utility shutdown across multiple facilities, or adapting to unexpected underground conditions, effective field coordination keeps electrical work aligned with site operations and construction milestones.
Underground Infrastructure
LeMaster Electric installs underground electrical infrastructure for Level 2 and DC fast charging (DCFC) stations throughout Washington State. Our capabilities include conduit systems, utility service pathways, duct banks, pull boxes, junction vaults, and electrical connections supporting commercial EV charging installations.
Working alongside general contractors, civil contractors, utilities, and EV charging developers, our team coordinates conduit routing, trench readiness, underground installations, inspections, and utility connections to deliver code-compliant infrastructure for new EV charging sites and expansions.
Equipment Assembly & Installation
Commercial EV charging stations rely on integrated electrical distribution equipment to safely deliver utility power to Level 2 and DC fast charging (DCFC) systems. Each component serves a critical role in power distribution, metering, voltage transformation, and vehicle charging.
Electrical Equipment Installation Includes:
- Electrical switchgear and switchboards
- Utility and distribution transformers
- CT metering cabinets and meter enclosures
- Electrical distribution panels and panelboards
- EV charging power cabinets
- Level 2 EV charging stations
- DC fast charging (DCFC) dispensers
LeMaster Electric assembles, sets, mounts, anchors, and electrically connects this equipment as part of commercial EV charging infrastructure construction throughout Washington State. Installation includes equipment positioning, conductor terminations, grounding and bonding, and electrical interconnections, with coordination across utility providers, equipment manufacturers, and construction teams to support inspections, energization, and commissioning.
GFCI Breaker Acceptance Testing
LeMaster Electric coordinates third-party GFCI breaker acceptance testing for commercial EV charging infrastructure throughout Washington State. Following electrical installation, specialized testing partners perform applicable ANSI/NETA ATS inspections and testing to verify ground-fault protection and breaker operation before energization and commissioning.
Testing services include:
- Visual & Mechanical Inspections: Verify breaker installation, ratings, connections, and protective settings.
- Electrical Testing: Perform applicable insulation resistance, contact resistance, and current-injection testing.
- Ground-Fault Protection Verification: Confirm protective device pickup, trip timing, sensor connections, and operation.
- Acceptance Test Documentation: Provide recorded test results, deficiencies, and corrective retesting for project closeout.
Testing procedures follow manufacturer requirements, applicable standards, and project specifications.
Startup & Commissioning Support
Successful EV charger commissioning starts with a properly prepared electrical installation. Before Level 2 and DC fast charging (DCFC) stations can become operational, specialized commissioning teams verify equipment functionality, configure charging systems, and perform final operational testing.
Commissioning readiness includes:
- Equipment assembly and installation verification
- Conductor termination and torque verification with witness marks
- Grounding, bonding, and circuit identification
- Electrical inspections and GFCI acceptance testing coordination
- Utility energization readiness and scheduling coordination
- On-site electrical support for commissioning teams
Thorough preparation helps commissioning specialists focus on charger activation and performance testing rather than correcting installation deficiencies, reducing avoidable delays and repeat site visits. LeMaster Electric supports commercial EV charger startup and commissioning throughout Washington State with an emphasis on installation quality, coordination, and operational readiness.
