EV Charger Installation (G04)
Electric vehicle ownership requires home charging for convenience – proper installation ensures safety and optimal charging speed.
This BidScope guides you through EV charger types: Level 1 (standard 120V outlet, slowest 3-5 miles range per hour), Level 2 (240V dedicated circuit, most common home installation, 25-30 miles per hour), and DC Fast Charging (commercial/public, very expensive, 100+ miles in 20-30 minutes).
Learn Level 2 charger selection: hardwired versus plug-in (NEMA 14-50), amperage options (32-amp most common, 40-amp or 48-amp for faster charging), smart features (WiFi connectivity, scheduling, load management), cable length adequate for parking location.
Understand electrical requirements: dedicated 240V circuit required, circuit sizing based on charger amperage (40-amp breaker for 32-amp charger per 80% rule), wire sizing (typically 8-gauge for 40-amp, 6-gauge for 50-amp), conduit run from panel to charger location.
Master installation locations: garage wall mount most common, outdoor weatherproof units, pedestal mounting for driveways, distance from panel affects cost.
Navigate permit requirements: electrical permit required, inspection by building department, utility notification in some areas.
Learn smart charging features: schedule charging for off-peak rates, monitor energy usage, integrate with solar systems, load management for multiple chargers or to prevent panel overload.
Understand utility programs: time-of-use rates for EV charging (cheaper at night), special EV rates from some Utah utilities, demand charges for commercial installations.
Know future-proofing: install higher-amp circuit even if current car doesn’t need it, pre-wire for second charger if planning multiple EVs, consider load management panel for multiple chargers.
Calculate costs: Level 2 charger unit $400-900, installation $500-2,000 depending on distance and complexity, total $900-2,900 typical.
This tool ensures your EV charging setup is safe, efficient, and ready for future vehicles.
