Rosenthal Electric - Berkeley's Top-Rated Electrical Contractor

Older Berkeley homes often have outdated knob-and-tube wiring or insufficient grounding, which can be a safety concern. Our team specializes in these projects, understanding how to carefully update the electrical system while preserving the home's architectural integrity. We navigate plaster walls and unique layouts to install modern, safe wiring and panels that meet current code without compromising the classic style you love.

This is a common issue in our area and often points to GFCI (Ground Fault Circuit Interrupter) outlet failures or underlying wiring problems. GFCIs, which are crucial for safety in wet areas, can wear out over time. We can diagnose whether it's a faulty outlet, an overloaded circuit common in older panels, or a deeper wiring issue. Our inspection will identify the root cause and provide a lasting repair to ensure your home's safety.

The key considerations are your home's existing electrical capacity and the charger's location. Many older homes in Berkeley and Oakland need a service panel upgrade to handle the new load safely. Our licensed electricians will assess your panel, recommend the correct circuit breaker and wiring, and ensure the installation is permitted and up to code. We handle everything from the panel to the mounting of the charging unit itself.
