Residential EV Charging and Solar PV Installation Guide

This white paper provides guidance on best practices for residential electric vehicle (EV) charging and solar photovoltaic (PV) installations, specifically addressing the potential for high-resistance connections in circuit breakers. It outlines the challenges associated with improper installation and maintenance of circuit breakers in home electrical systems, particularly in the context of high-current and high-cycle loads. The document emphasizes the importance of proper site preparation to ensure safety and reliability during the installation process. It details specific recommendations, such as considering the replacement of aluminum components with copper for improved conductivity, and provides step-by-step instructions for cleaning busbars to prevent corrosion. The paper also identifies warning signs for higher-risk installations, including visible damage to busbars and line stabs. By following these guidelines, homeowners can enhance the performance and safety of their electrical systems during the energy transition.
