Level 3 (DC Fast) Charger Installation
DC fast charging is a different class of build from the AC charging that covers most parking lots. Instead of feeding alternating current to a vehicle and letting its onboard charger handle the conversion, a Level 3 unit converts power to direct current inside the charger and delivers it straight to the battery — adding a substantial charge in the time it takes to run an errand rather than over an evening. That speed comes at a cost: far more demanding electrical infrastructure behind the unit.
That infrastructure is what separates a workable DC fast project from a stalled one. FTCI brings the high-capacity electrical work and utility coordination these installations require, as part of a complete EV charging installation and maintenance practice that runs from first assessment through commissioning.
Where DC Fast Charging Makes Sense
Speed is the whole point, so location follows demand. DC fast charging pays for its added complexity where drivers won’t — or can’t — wait around. Highway corridors, high-traffic retail and travel stops, and public charging hubs are the natural fit, giving drivers enough range in minutes to keep moving.
Fleets that run on a schedule lean on it too. Operations that need vehicles back in service quickly rather than parked overnight often build around fast charging to keep turnaround tight. The electrical demand is heavier, but for a fleet measured on uptime, the faster cycle can be worth the investment.
Why Level 3 Is a Bigger Electrical Lift
The jump from Level 2 to Level 3 isn’t incremental. Where a Level 2 unit draws the kind of 240-volt service a building may already have to spare, a DC fast charger commonly pulls anywhere from 50 kilowatts into the hundreds — enough that a single high-power unit can rival the demand of a small building. Meeting that almost always means three-phase power, heavy conductors, and dedicated service the existing infrastructure was never built to provide.
More often than not, that triggers a utility service upgrade before installation can begin — a new transformer, upgraded switchgear, and coordination with the utility on capacity and timing. FTCI holds a long-standing reputation with utilities for seamless cutovers, and keeps the metering equipment and switchgear that drive these upgrades on hand, so the project isn’t left waiting on the single longest lead item in the build.
What a DC Fast Installation Involves
A Level 3 build moves through heavier versions of the same phases any charging project follows, with the electrical and civil scope scaled up accordingly. Keeping all of it under one team is what holds the schedule together when the work is this involved.
Utility Service And Power
The service feeding the chargers is the foundation of the entire project. That means confirming available capacity, coordinating the upgrade with the utility, and setting the transformer, switchgear, and metering the units will draw from — the high-capacity electrical work that defines a DC fast build.
Civil And Equipment Pads
Fast-charge units and their supporting equipment are large and heavy, calling for engineered pads, conduit runs, and often substantial trenching. FTCI’s in-house civil crews handle this groundwork directly, keeping it in step with the electrical scope rather than waiting on an outside contractor.
Equipment Set And Commissioning
Once power and pads are in place, the chargers are set, terminated, energized, and tested against the standards they’ll operate under. Every unit is verified before the site opens, held to the same benchmark as every FTCI project — 100% completion on the first try with zero go-backs, and safety maintained from the first day on-site through final closeout.
Planning Around the Utility Timeline
On most DC fast projects, the schedule is set less by the install itself than by everything that has to happen before it. Utility capacity, equipment lead times, and permitting can stretch a timeline for months if they aren’t managed from the outset. Several factors tend to govern how quickly a project can move:
- Available utility capacity at the site and the scope of any required upgrade
- Lead times on transformers, switchgear, and metering equipment
- Permitting and utility review timelines
- Coordination between the civil, electrical, and utility work
FTCI works to compress the parts of that timeline within reach — keeping long-lead switchgear and metering in stock, and leaning on established utility relationships to keep cutovers and approvals moving. The parts outside anyone’s control get planned around early, so they surface as scheduling inputs rather than mid-project surprises.
