Installing a subpanel adds electrical capacity and creates dedicated space for new circuits without replacing your main electrical panel when an upgrade is not required. ELC Contractor provides subpanel installation and upgrades throughout the Bay Area for EV chargers, ADUs, remodels, garages, workshops, heat pumps, and other electrical needs
Add dedicated circuits for new appliances, equipment, and home upgrades
Add electrical capacity for EV charger installation and future charging needs
Provide dedicated power for ADUs, additions, garages, and remodeling projects
Support heat pumps, HVAC equipment, induction ranges, and other high-demand loads
Professional subpanel installation with permits and inspections when required
Distribute electrical loads efficiently between the main panel and subpanel
A subpanel may be the right solution when your main electrical panel still has sufficient service capacity but you need more circuit space or dedicated power for new electrical loads. Our licensed electricians evaluate your existing panel, electrical load, and planned equipment before recommending a subpanel installation or main panel upgrade
No More Circuit Space
Your main panel may have enough service capacity but not enough available breaker spaces for new circuits
EV Charger Installation
A subpanel can provide dedicated circuit space for EV charging equipment and future electrical needs
ADUs & Home Additions
Add dedicated electrical distribution for ADUs, remodels, garages, workshops, and additions
Heat Pumps & Appliances
New heat pumps, HVAC equipment, induction ranges, dryers, or other high-demand appliances may require additional circuits
Multiple New Circuits
A subpanel can organize several new circuits in one location and simplify future electrical expansion
Remote Electrical Loads
Garages, workshops, detached structures, and other areas may benefit from a nearby subpanel for better power distribution
Our electricians evaluate your existing panel, electrical load, and available capacity to determine whether a subpanel is the right solution for your project
A subpanel adds circuit space and helps distribute electrical loads, while a main panel upgrade may increase overall service capacity or replace outdated equipment. The right solution depends on your existing panel, available capacity, electrical load, and future power needs
Adds dedicated circuit space without replacing the main electrical panel when sufficient service capacity is already available
Replaces or upgrades the main panel when additional circuit space, newer equipment, or higher electrical demand requires it
Increases the electrical service available to the property, such as upgrading from 100A to 200A, and may involve utility coordination, permits, and inspection
A subpanel does not increase the electrical service coming into your home. We evaluate the existing system and electrical load before recommending the right solution
The right subpanel size depends on your existing electrical service, calculated load, available main panel capacity, and the equipment you plan to add. Our electricians evaluate the system before recommending the appropriate subpanel size and feeder
Before recommending a subpanel installation, we evaluate your existing electrical service, main panel capacity, current electrical load, and planned future loads. The right subpanel size depends on the actual load calculation, available capacity, and how the electrical system will be used
Common for smaller additions, garages, workshops, and limited new circuits
A common choice for larger garages, ADUs, remodels, and multiple new circuits
May be appropriate for larger additions, higher electrical demand, or future expansion
EV charging equipment can significantly affect subpanel sizing and load calculations
Heat pumps, HVAC equipment, dryers, ranges, and other high-demand loads must be included in planning
Additional circuit space may help support future electrical upgrades and equipment
A larger subpanel does not automatically mean your home has more electrical service capacity. Final sizing should be based on load calculations and the existing electrical system
NOT SURE WHAT SIZE SUBPANEL YOU NEED?
We evaluate your existing electrical service, available panel capacity, and planned electrical loads to determine whether a subpanel is the right solution for your project
Subpanel Installation & Circuit Organization

We test the installation, verify proper operation, complete labeling, and finalize inspection requirements
We’re here for questions and future electrical needs
Find answers to common questions about a subpanel installation, permits, PG&E coordination, installation timelines, and electrical service capacity
Permit requirements depend on the project and local jurisdiction. When a permit is required, ELC Contractor can coordinate the permit and inspection process as part of the installation
Yes, in many cases a subpanel can be added without replacing or upgrading the main panel, as long as the existing electrical service has sufficient capacity for the planned loads.
The correct size depends on the available service capacity, calculated electrical load, number of new circuits, and future electrical needs. Common subpanel sizes include 60A, 100A, and 125A, but final sizing should be based on the actual system
Yes. Subpanels are commonly installed in garages, ADUs, workshops, additions, and other areas where dedicated circuit space or local electrical distribution is needed.
No. A subpanel adds circuit space and helps distribute electrical loads, but it does not increase the amount of electrical service supplied to the property.
The right solution depends on your existing panel condition, available breaker space, service capacity, calculated load, and future power needs. Our electricians evaluate the system before recommending a subpanel installation or main panel upgrade.
