Expert Electrical Wiring for New Homes & Buildings
Expert Electrical Wiring for New Homes & Buildings
When it comes to building a new home, office, retail space, or multifamily structure, the quality and reliability of your electrical system is one of the most critical components of the project. At White Marsh Power & Electric, we bring over a decade of experience in new construction wiring throughout Perry Hall, White Marsh, and greater Baltimore County.
Whether you’re a homeowner, builder, developer, or investor, we deliver professional, code-compliant installations that are tailored to your layout, energy needs, and future expansion.
Why New Construction Wiring Requires a Pro
New construction wiring is not the same as repairs or renovations. This is ground-up infrastructure work that must be done cleanly, correctly, and safely from the start. Mistakes made at this phase can cost tens of thousands in future repairs or lead to dangerous conditions.
Here's what makes this work complex:
✅ Load Calculations: Each home or commercial space requires a calculated electrical load to determine the proper size of your service, panel, and wiring system.
✅ Blueprint Interpretation: Accurate reading of architectural and electrical blueprints ensures all switches, receptacles, lighting, and circuits are correctly located.
✅ Code Compliance: NEC (National Electrical Code) compliance is non-negotiable. Permits and inspections must be passed at each phase (rough-in and final).
✅ Coordination: Electricians must work in tandem with framing, HVAC, plumbing, and drywall crews to keep the build moving efficiently.
✅ Future-Proofing: We help plan for smart home features, solar upgrades, EV charging, generators, and structured cabling.
Our master electrician ensures every project meets code, satisfies utility company requirements, and passes inspection the first time.
We follow a structured and professional process for new construction electrical work:
Pre-Construction Consultation: We review blueprints, building specs, and coordinate with the GC, architect, and homeowner.
Load Calculations & Planning: Service size (typically 200A or 400A) is determined based on square footage, HVAC loads, and electrical needs.
Rough-In Phase: We install boxes, conduit, wire runs, and service panel(s) before insulation and drywall.
Inspection & Utility Coordination: We schedule county inspections and coordinate with BGE or your local utility for service activation.
Trim-Out Phase: Once walls are up, we install switches, outlets, fixtures, smoke detectors, bath fans, and test the system.
Final Inspection & Walkthrough: We perform a comprehensive inspection, confirm code compliance, and verify satisfaction.
