Property-specific branch-circuit installation for appliances, workshops, offices, and specialty equipment, sized to the connected load and existing panel. Trusted by homeowners throughout Montgomery County since 1996.
A new appliance or piece of equipment needs more than an open breaker space. AJ Long Electric reviews the nameplate and manufacturer instructions, voltage and load, duty cycle, disconnect and receptacle requirements, panel capacity, breaker compatibility, and the route between the panel and equipment. The resulting scope may be a dedicated branch circuit, a feeder and subpanel, or a different capacity solution when the existing service cannot support the planned load. We also identify access, firestopping, exterior exposure, trenching, and finish-restoration boundaries before work is authorized. Permit and inspection requirements are confirmed for the address and defined installation rather than assumed from the service name alone. For a Germantown property, the recommendation follows the actual equipment, access, electrical capacity, and project goals documented during the assessment.
AJ Long Electric defines the dedicated circuits scope for the individual Germantown 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 Montgomery County Department of Permitting Services; permit, inspection, and utility responsibilities are stated in the proposal for the address.

AJ Long Electric starts with the equipment and existing electrical system, then defines the branch-circuit route, protection, access, and permit coordination in writing. That avoids treating very different appliance and property conditions as one fixed package.

Conductors, protection, and connection equipment follow the actual appliance or equipment requirements.
Capacity, breaker space, compatibility, and existing demand are checked before adding the circuit.
The proposal identifies access, conductor path, mounting, penetrations, and restoration boundaries.
Equipment that requires an individual branch circuit is separated from unrelated receptacles and loads.
The completed circuit is labeled and tested to the approved scope.
For dedicated circuits at this Germantown 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 Montgomery County Department of Permitting Services and review the NFPA 70 (National Electrical Code).
We document voltage, load, connection, location, and manufacturer requirements.
Capacity, compatibility, breaker space, access, and conductor path are evaluated.
The estimate identifies the circuit, protection, connection method, access work, and exclusions.
The authority and inspection path are confirmed for the property and project.
The approved circuit is installed, labeled, and checked at the connection point.
That depends on the equipment nameplate, manufacturer instructions, connected load, and adopted electrical requirements. We verify the actual appliance rather than relying on a generic list.
Sometimes. Available breaker space alone is not enough; we also review panel compatibility, service capacity, existing demand, and the proposed load. The assessment determines whether a branch circuit, subpanel, load-management option, or service work is appropriate.
Voltage, maximum load, continuous-duty requirements, starting current, conductor length, temperature, installation method, and manufacturer instructions can affect conductor and breaker sizing.
Panel and equipment locations, finished walls and ceilings, framing, fire-rated assemblies, exterior exposure, crawl or attic access, trenching, and restoration boundaries all shape the route.
Requirements depend on the address and defined scope. AJ Long Electric confirms the applicable permit and inspection path before work begins.
The equipment, electrical capacity, access, property layout, and local authority can change the scope from one Germantown 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 Germantown address.
