Monte Power & Electric installs 60A to 200A subpanels across San Jose and the South Bay. ADU distribution, detached garage and workshop feeds, kitchen remodel circuits, pool and spa equipment, and dedicated tenant or equipment runs. Permit pulled, AHJ inspection handled.
What we do
Subpanels solve the in-between problem. The main is fine, the service is sized for the property, but the new ADU, kitchen remodel, detached garage, or equipment install needs its own distribution. Monte Power & Electric handles the feeder design, the trench if it's an outbuilding, the conductor pull, the panel set, and the inspection.
Most subpanel jobs are quick: a half-day to two days depending on whether the run is attached or buried out to a detached structure. The harder part is sizing the feeder correctly the first time, which avoids ripping out conduit when the loads grow into the panel.
By application
Subpanel design is more about the loads than the square footage. Walk us through the appliance plan and we'll spec the feeder.
Most-common in San Jose
100A or 125A subpanel for an attached or detached accessory dwelling unit. Sized for heat pump, induction range, EV charger, and the standard ADU lighting and small-appliance load.
Hobbyist & pro shops
60A or 100A feed to a detached garage, workshop, or studio. Common loads: 240V tool circuits, dust collection, lighting, EV charger, and welder or air-compressor circuits. Trenched conduit included.
When the main is full
Some 1980s and 1990s San Jose homes have a 200A main with no open breaker positions. Adding a kitchen subpanel keeps the main alone and adds dedicated 20A small-appliance, range, dishwasher, and disposal circuits in one clean location.
Dedicated equipment feeds
Pool and spa equipment, well pumps, irrigation, large workshop tools, or commercial tenant equipment runs that benefit from a dedicated subpanel near the load.
When a subpanel is the right answer
Most of the time the main panel is fine and adding a subpanel is faster, cleaner, and cheaper than upsizing the service.
How a subpanel install goes
Same disciplined sequence whether the project is an attached kitchen subpanel or a detached ADU feed.
On-site walk. Load list reviewed, main panel headroom checked, feeder route planned, AHJ rules confirmed. No charge.
Itemized quote with line items for feeder breaker, conductors, conduit, trenching, subpanel, branch circuits, and permit.
Electrical permit pulled. Trench dug if the run goes to a detached structure. AHJ trench inspection scheduled before backfill.
Subpanel mounted, conductors pulled and terminated, feeder breaker landed in the main. Branch circuits run, devices trimmed.
