Property-specific Level 2 EV charger installation with panel-capacity review, a dedicated circuit, equipment connection, testing, and permit-path confirmation. Trusted by homeowners throughout Prince George's County since 1996.
AJ Long Electric plans home EV charging around the vehicle, charger, parking location, and available electrical capacity. A licensed electrician reviews the panel, completes the load assessment needed for the proposed charging load, and explains whether the existing service can support the project. The installation scope can include a hardwired wall connector or a receptacle-based EVSE setup, an appropriately sized dedicated circuit, required protection, secure mounting, labeling, and commissioning. Charging output is not universal: it depends on the vehicle's onboard charger, the EVSE setting, circuit capacity, temperature, and other site conditions. Before work begins, we confirm the applicable permit and inspection path for the address and define any panel, routing, trenching, or load-management work separately. For a Greenbelt property, the recommendation follows the actual equipment, access, electrical capacity, and project goals documented during the assessment.
AJ Long Electric defines the ev charger installation scope for the individual Greenbelt address. The written proposal identifies known conditions, access assumptions, included electrical work, exclusions, and any coordination that must be confirmed before scheduling. Before work begins, we confirm whether the defined scope requires coordination with the Prince George's County Department of Permitting, Inspections & Enforcement; permit, inspection, and utility responsibilities are stated in the proposal for the address.

AJ Long Electric starts with electrical capacity and site conditions, then defines a charger connection that fits the vehicle and property. Homeowners receive a written scope that distinguishes the EV circuit from any optional panel, routing, trenching, or restoration work. Permit and inspection coordination is described only after the address and project scope are confirmed.

The proposed charging load is evaluated against the home's existing electrical demand.
Circuit and equipment choices account for the vehicle, connector, parking position, and daily charging needs.
The estimate identifies routing, mounting, protection, panel work, and permit coordination that apply to the property.
A dedicated, professionally installed circuit avoids improvised extension-cord charging arrangements.
The completed connection is labeled, tested, and reviewed with the homeowner.
For ev charger installation at this Greenbelt property, AJ Long Electric begins by reviewing the requested outcome, relevant equipment, safe access, and observed electrical conditions. The written proposal identifies the defined work, sequencing, coordination responsibilities, and exclusions. Authorized work is tested and documented to the completed scope; newly exposed conditions are discussed before the scope changes.

Permit fees, scope, and existing-condition surprises affect final pricing. Verify current requirements with the Prince George's County Department of Permitting, Inspections & Enforcement and review the NFPA 70 (National Electrical Code).
We confirm the vehicle, selected EVSE, parking location, and daily charging needs.
A licensed electrician evaluates panel capacity, existing demand, breaker space, and the proposed circuit route.
We explain compatible output, hardwired or receptacle-based choices, routing, and any capacity work.
The applicable permit and inspection requirements are confirmed for the property and scope.
The approved circuit, protection, mounting, and equipment connection are completed to the defined scope.
We test the installation, label the circuit, and review normal operation with the homeowner.
Charging output varies by vehicle, EVSE setting, circuit capacity, temperature, and battery conditions. We use the vehicle and charger specifications to plan a compatible circuit rather than promise one universal miles-per-hour figure.
Not necessarily. We review service size, existing demand, breaker space, and the proposed charging load. When capacity is constrained, the options may include a lower EVSE setting, listed load-management equipment, targeted panel work, or a service upgrade.
We connect customer-selected EVSE equipment when it is compatible with the vehicle, electrical system, mounting location, and manufacturer instructions. Equipment selection and availability are confirmed for the individual project.
An outdoor installation may be feasible when the selected equipment and wiring method are rated for the location. We evaluate mounting, weather exposure, cable reach, physical protection, and the route back to the panel.
The IRS states that Section 30C is unavailable for property placed in service after June 30, 2026. See the current IRS guidance at https://www.irs.gov/credits-deductions/alternative-fuel-vehicle-refueling-property-credit and consult a qualified tax professional; AJ Long Electric does not provide tax advice or determine eligibility.
The equipment, electrical capacity, access, property layout, and local authority can change the scope from one Greenbelt address to another. AJ Long Electric confirms those conditions and the applicable coordination path before finalizing the proposal.
Cost depends on the equipment, electrical capacity, access, route, corrective work, and local coordination required at the property. AJ Long Electric provides a written estimate after the relevant conditions and project boundary are assessed.
Permit and inspection requirements depend on the address and the defined electrical scope. AJ Long Electric confirms the applicable path with the authority serving the property and states the included coordination in the written proposal.
Timing depends on the defined scope, safe access, equipment and material availability, property conditions, and any permit, inspection, utility, or other-trade coordination. AJ Long Electric confirms the anticipated sequence after the assessment.
AJ Long Electric has served the region since 1996. We are a licensed, insured electrical contractor led by a master electrician, and we define the scope, access assumptions, exclusions, and project-specific coordination before authorized work begins.
Scheduling depends on the current workload and the project scope. Call (571) 444-6886 or request an appointment online and we will confirm the earliest available time for your Greenbelt address.
