- Code reference
- Centennial is in Climate Zone 5B.
- Code reference
- The code applies to alterations, additions, and remodels per IECC Chapter 5 (existing buildings), with the prescriptive requirements of Chapter 4 (or equivalent U-factor/UA paths) generally applying to new or modified portions of the thermal envelope.
- Code reference
- Key prescriptive requirements relevant to remodels/additions (drawn from 2018 IECC Table R402.1.2 and related sections for CZ 5; these are the base code values with no local amendments identified that alter them):
- Ceiling/attic insulation
- Minimum R-49 (or equivalent U-factor ≤ 0.026).
- Adopting reference
- 2018 IECC R402.1.2 (Table R402.1.2).

What a Level 2 install actually covers
A Level 2 EV charger install adds a dedicated 240-volt branch circuit and mounts a wall, pedestal, or hardwired charging unit at the parking location. Typical scope includes a site assessment and NEC Article 220 load calculation on the existing service, permit application with the local authority, circuit rough-in, charger mounting and termination, functional testing, and final inspection. If the panel cannot support the continuous EV load, the scope may expand to a service or sub-panel upgrade before the charger circuit is added.
text
Electrical scope and equipment classes
Most residential Level 2 units land on a 40- to 50-amp double-pole breaker. A 48-amp continuous charger is commonly planned on a 60-amp circuit because Colorado follows the 2020 NEC requirement to size new continuous loads at 125 percent. Wiring is typically copper sized to the breaker and charger rating—often 6 AWG copper for a 48-amp unit—run in approved methods and protected from physical damage, frequently in conduit for exposed or outdoor segments. Connection is either hardwired or a NEMA 14-50 receptacle; hardwiring is usually preferred outdoors for weather resistance. GFCI protection is required for most 240V Level 2 charging circuits. Outdoor units should carry at least a NEMA 3R enclosure rating, with NEMA 4 preferred for Denver hail, freeze-thaw, and wind-driven rain. Common equipment classes include Wi-Fi-capable residential wall connectors and flexible amperage units such as ChargePoint Home Flex, Grizzl-E, Emporia, and Tesla Wall Connector, selected to match vehicle inlet, cable reach, and scheduled-charging needs.

Mounting locations and site conditions
Exterior wall mounts near the garage or panel path are the simplest when structure and parking alignment allow. Pedestal mounts serve driveways or parking pads without a usable wall and usually need a concrete footing. Detached garages or across-yard parking require trenched conduit from the main panel or a suitably placed sub-panel. Placement should balance cable reach to the charge port, protection from traffic and snow storage, and distance back to the electrical source so conductor length and voltage drop stay practical.

Denver permits, codes, and inspections
In the City and County of Denver, an electrical permit is required for Level 2 charger work through Community Planning and Development, with a final inspection after install. Inspectors look for correct grounding, conductor sizing, overcurrent protection, GFCI where required, and work matching the permitted scope. Installations must follow NEC Article 625 for EV power transfer systems and NEC Article 220 load-calc methods for panel capacity. The Denver Energy Code also drives EV-ready provisions on many new garages and carports: a 240-volt, 40-amp branch circuit path, a dedicated EV-ready breaker space, and a receptacle or charging connection at the parking space. Metro suburbs follow their own building departments and may apply state or local amendments, so jurisdiction is confirmed before rough-in.

Panel capacity and when upgrades enter the job
Older Denver-metro housing often still has 100-amp service. A proper load calculation determines whether spare capacity exists for a continuous Level 2 load or whether a panel upgrade, feeder change, or sub-panel is required first. Skipping that step risks nuisance tripping, rejected inspection, or an undersized install that cannot support the charger rating the vehicle needs. Xcel Energy and other programs sometimes offer rebates on qualifying Level 2 equipment; rebate paperwork is separate from the electrical permit and depends on current utility rules and product eligibility.

How Autotelic runs the project
Autotelic is a municipally licensed Denver general contractor. For Level 2 EV charger work, we coordinate licensed specialty electrical trades for load calculation, circuit installation, panel work when needed, permit handling, and inspection readiness. That keeps design-build sequencing clear when charger install ties into garage remodels, driveway work, pedestal foundations, or broader electrical service changes.
FAQ
Common questions
Who handles the electrical permits and licensing?
Autotelic is a municipally licensed Denver general contractor and coordinates licensed specialty electrical trades for Level 2 charger circuits, panel evaluations, and related service work. The electrical permit is pulled with the local authority—in Denver, Community Planning and Development—and the finished install is left ready for required inspection.
Do I need a dedicated circuit for a Level 2 charger?
Yes. Level 2 equipment requires a dedicated 240-volt branch circuit with overcurrent protection sized to the charger rating and wire ampacity. Sharing the circuit with other loads is not acceptable under standard EV charging practice and code expectations.
Hardwired or NEMA 14-50—which is better outdoors?
Both are used, but hardwiring is generally more weather-resistant for permanent outdoor mounts. A NEMA 14-50 receptacle can be appropriate indoors or where a cord-and-plug setup is specified. Enclosure rating, GFCI requirements, and local inspection expectations guide the final choice.
Will my existing panel support a Level 2 charger?
Only a load calculation can answer that. Many older homes with 100-amp service need a panel or sub-panel upgrade before a 40- to 60-amp continuous EV circuit is added. The assessment should happen before equipment is purchased and before a final scope is locked.
What outdoor rating matters in Denver weather?
Use a charger listed for outdoor installation with at least a NEMA 3R enclosure; NEMA 4 is preferred where driving rain, dust, and hail exposure are concerns. Mounting height, cable management, and protection from vehicle paths and snow storage matter as much as the enclosure rating.
Are utility rebates part of the install?
Sometimes. Programs such as Xcel Energy rebates may apply to qualifying Level 2 equipment and installations, but eligibility, product lists, and documentation change. Rebate support is coordinated around the electrical scope; it is not a substitute for the permit or inspection.
