Mixed-Use Service Upgrade & Electrical Modernization on Taraval Street
Max Electric completed a service upgrade and electrical modernization for a mixed-use San Francisco property with three commercial spaces and one residential unit. The work replaced outdated fuse panels, corrected unsafe wiring conditions, and gave each unit its own dedicated 125A service.
Modernizing a mixed-use property with outdated electrical service
This Taraval Street property included three commercial spaces and one residential unit, each needing safer and more clearly organized electrical service. The existing system had outdated fuse panels, older wiring conditions, and years of modifications that made the service layout difficult to identify.
Max Electric replaced the outdated equipment, corrected unsafe wiring conditions, and installed new electrical service equipment so each unit could receive its own dedicated 125A service. The project combined fuse box replacement and service equipment upgrades with detailed electrical troubleshooting.
The final installation improved safety, organization, and long-term usability for both commercial tenants and the residential unit. It also created a cleaner exterior service area, improving the building’s curb appeal while making the system easier to understand and maintain.
What the property needed from the upgrade
The project had to solve several problems at once: old fuse equipment, unsafe wiring conditions, unclear tenant service separation, and limited access behind the electrical equipment.
Three commercial spaces and one residential unit were included in the service upgrade.
Each unit received its own dedicated 125A service for clearer and safer power distribution.
The scope included service equipment, troubleshooting, wiring corrections, and modernization work.
The completed installation replaced years of confusing modifications with organized service equipment.
Electrical services completed by Max Electric
The work combined a service upgrade, fuse panel replacement, wiring corrections, service equipment installation, and mixed-use building troubleshooting.
Service Upgrade
The building’s electrical service was upgraded to support separate 125A service for each unit.
Fuse Box Replacement
Outdated fuse panels were replaced with modern service equipment designed for safer operation.
Meter & Service Equipment Upgrade
New exterior service equipment was installed to create a cleaner and more organized layout.
Electrical Troubleshooting
Existing wiring was traced to identify unsafe conditions and possible cross-feeding between tenants.
Wiring Corrections
Unauthorized wiring modifications and improper connections were corrected during the modernization.
Weatherhead Corrections
Improper weatherhead-related conditions were addressed as part of the service upgrade scope.
Mixed-Use Building Electrical Work
The system was reorganized for a property serving both commercial spaces and one residential unit.
Electrical Modernization
The final installation improved safety, identification, access, and long-term serviceability.
Untangling years of unsafe and unclear electrical modifications
One of the main challenges was figuring out what the existing wiring was actually doing. The property had years of unauthorized changes, including improper weatherhead connections and wiring that appeared to cross-feed neighboring tenants.
For a mixed-use property, unclear electrical separation is not just inconvenient. It can create safety issues, billing confusion, service access problems, and major complications during future repairs. The system needed to be traced, reorganized, and corrected before the new service equipment could deliver the intended result.
Existing wiring traced
Our team identified how the old wiring was routed and where unsafe or unclear connections needed correction.
Tenant service separation clarified
The upgraded layout gave each unit its own dedicated service instead of relying on a confusing legacy setup.
Unsafe conditions corrected
Improper modifications were replaced with a safer, cleaner, and more clearly identified electrical installation.
Routing new wiring through a very limited crawl space
Another major challenge was access. A very small crawl space behind the electrical equipment limited the working area and made routing new wiring more difficult than a typical exterior service replacement.
Despite the tight conditions, Max Electric routed new wiring, reorganized the service equipment, and completed the installation in a way that improved both safety and the exterior appearance of the building. The final result was cleaner, easier to identify, and better suited for long-term maintenance.
What the corrected system supports
The upgraded service layout gave the building safer electrical separation and a more practical foundation for future repairs, inspections, and tenant changes.
How the service upgrade was handled
The project required careful investigation, correction of unsafe wiring, replacement of old service equipment, and a clean final installation.
Existing conditions reviewed
We inspected the old fuse panels, service equipment, weatherhead conditions, and wiring layout before starting the upgrade.
Wiring traced and corrected
Unauthorized modifications and unclear tenant wiring were identified, reorganized, and corrected.
New service equipment installed
Modern equipment was installed to provide each commercial and residential unit with dedicated 125A service.
Final layout cleaned up
The finished installation improved safety, visibility, service access, and the exterior appearance of the property.
The result: safer dedicated service for a mixed-use property
Max Electric completed the service upgrade and electrical modernization for the Taraval Street property, replacing outdated fuse panels and reorganizing the electrical service around four separate units. Each unit now has its own dedicated 125A service, reducing confusion and improving long-term usability.
The project corrected unsafe legacy wiring, addressed improper modifications, improved tenant service separation, and delivered a cleaner exterior installation that better fits the building’s current commercial and residential use.
Old fuse equipment replaced
The outdated panels were removed from the active service layout and replaced with modern equipment.
Unsafe wiring corrected
Improper and unclear wiring conditions were traced, reorganized, and corrected during the upgrade.
Clean exterior service layout
The final installation improved the building’s electrical organization and curb appeal.
Before, correction work, and final service equipment
The project moved from old fuse equipment and unsafe wiring conditions to a clean exterior service installation with clearly organized equipment.
