• Increased likelihood of electrical fires due to deteriorated insulation

By replacing every wire, switch, and receptacle, HEP eliminates hidden hazards and creates a robust backbone ready for decades of reliability.

The HEP Whole Home Rewire Workflow

Project Evaluation and Scope Setting

HEP’s process starts with a thorough walkthrough and documentation of the existing electrical system. Technicians inspect:

• Panel amperage and breaker condition
• Grounding and bonding pathways
• Branch circuit layout and conductor type
• Accessibility of crawl spaces, attics, and wall cavities
• Presence of aluminum wiring or cloth-wrapped conductors

This evaluation becomes the blueprint for a customized rewire roadmap specific to the property’s size, construction style, and future power demands.

Detailed Load Calculations

Properly sizing the service panel and branch circuits prevents nuisance tripping and provides headroom for future upgrades such as:

• Solar inverter interconnections
• Battery storage systems
• Outdoor kitchens or workshops
• Media rooms with high-draw electronics

HEP electricians calculate maximum demand loads per National Electrical Code (NEC) Article 220, then add growth capacity to ensure the new system will not reach its limits prematurely.

Material Selection Aligned with Modern Standards

Choosing the right wiring method affects durability, safety, and energy efficiency. HEP typically specifies:

• Copper conductors with THHN/THWN-2 insulation for superior conductivity
• AFCI (Arc-Fault Circuit Interrupter) breakers to mitigate arc-induced fires
• Dual-function AFCI/GFCI protection in kitchens, bathrooms, and laundry areas
• Tamper-resistant receptacles to safeguard children
• Metal or PVC conduit in locations requiring extra mechanical protection

Strategic Circuit Distribution

Instead of relying on “daisy-chained” receptacles, HEP balances loads across multiple circuits. Dedicated lines are installed for:

• Refrigerators and freezers
• Microwaves and convection ovens
• Garage door openers and power tools
• Home office equipment and network infrastructure

Balanced distribution prevents voltage drop and creates clear isolation points for troubleshooting.

Minimally Invasive Demolition and Routing

Oak Ridge homeowners often worry about drywall damage during a rewire. HEP employs methods that limit disruption:

• Fishing new cables through existing chases and stud cavities
• Leveraging attic and crawl space access to minimize wall penetrations
• Reusing switch box openings where feasible
• Coordinating cutting and patching with a tight workflow to reduce project duration

In-Progress Safety Controls

Throughout the project, HEP maintains strict safety protocols:

• Lockout/tagout procedures at the main service disconnect
• Temporary power setups for essential circuits (refrigeration, health equipment)
• Dust containment barriers and negative air machines to manage debris
• Daily site cleanup to limit tripping hazards

Load Testing and Final Verification

When all conductors are terminated, HEP performs:

• Insulation resistance tests with a megohmmeter
• Voltage drop measurements on long runs
• GFCI and AFCI functional testing
• Thermal imaging to detect hidden hotspots
• As-built documentation showing circuit maps and breaker assignments

Once every metric passes internal benchmarks, the work is scheduled for municipal inspection.
