Electrical Systems: The Foundation
Understanding building electrical infrastructure and upgrade requirements for successful electrification
Your Progress
Section 2 of 5Building Electrical Infrastructure
Most buildings were designed for much lower electrical loads than modern electrified systems require. A typical home might have a 100-200 amp electrical service, but adding electric heat pumps, EV charging, and efficient appliances can easily double or triple the electrical demand.
Successful electrification requires careful assessment of existing electrical capacity and strategic upgrades. This includes evaluating the main electrical panel, wiring, circuits, and grounding systems to ensure they can safely handle increased loads.
Safety First
Electrical upgrades must comply with local building codes and National Electrical Code (NEC) requirements. Improper installations can create fire hazards and void insurance coverage.
Electrical System Components
Main Electrical Panel
200-400 amps
Electrical Wiring
Based on gauge and insulation rating
Electrical Outlets
15-50 amps per circuit
Grounding System
Continuity and low resistance
