House Rewires: Understanding Outdated Wiring & Modern Solutions
Upgrading your home’s wiring is one of the most important electrical projects you can invest in. At Adel Home Services, we specialize in full and partial house rewires across Montgomery, Chester, Berks, and Lehigh Counties, ensuring your electrical system is safe, reliable, and compliant with the National Electrical Code (NEC) and Pennsylvania UCC requirements.
Common Types of Outdated Electrical Wiring
Many homes in Pennsylvania still contain wiring systems that no longer meet today’s safety standards. The NEC sets clear requirements for grounding, insulation, and safe wiring methods:
Knob-and-Tube Wiring (pre-1940s)
NEC Article 394 (Concealed Knob-and-Tube Wiring) restricts its use in new installations.
Hazards: brittle insulation, no grounding, unsafe splicing.
Cloth-Insulated Wiring (1940s–1960s)
Fails to meet modern insulation and temperature rating requirements (NEC Article 310).
Hazards: insulation crumbles over time, leading to arcing.
Aluminum Branch Circuit Wiring (1960s–1970s)
Covered under NEC 110.14 (Electrical Connections) due to overheating risks.
Hazards: expansion and contraction cause loose connections.
Two-Wire Ungrounded Circuits
NEC 250.4(A)(5) requires effective grounding for safety.
Hazards: unsafe for modern appliances and electronics.
If your home contains these systems, a rewire is strongly recommended for safety, insurance, and reliability.
NEC Code Requirements for Rewires
When performing house rewires, Adel Home Services follows all applicable NEC standards:
NEC Article 210 – Branch Circuits (requirements for receptacle spacing, GFCI, AFCI).
NEC Article 220 – Load Calculations (ensuring panel and service sizing match demand).
NEC Article 230 – Services (rules for service conductors, meter bases, and disconnects).
NEC Article 240 – Overcurrent Protection (proper breaker sizing for wiring).
NEC Article 250 – Grounding and Bonding (critical for safety and insurance compliance).
NEC Article 406 – Receptacles, Cord Connectors, and Outlets (modern tamper-resistant and weather-rated devices).
