What we handle: Electrical Panel Upgrade in Mountain View
Your electrical panel sets the limit on everything else in the building. If yours is full, outdated or only rated for 100 amps, adding an EV charger, air conditioning or an induction range can push it past what it was built for. An electrical panel upgrade in Mountain View gives you the capacity and the breaker protection modern loads need.
100 amp to 200 amp upgrade
New meter base, service entrance conductors, grounding and main panel sized for double the capacity.
Breaker box replacement
Outdated panel brands and worn bus bars replaced with a current, fully labeled load center.
Fuse box replacement
Screw-in fuse panels converted to breakers, with circuits separated and grounded as the wiring allows.
Sub panel installation
Added capacity for garages, ADUs, workshops, additions and pool equipment without replacing the main.
Main panel and service upgrade
Meter, mast or underground service, main breaker and grounding brought up to current code together.
200 amp panel upgrade
The standard for modern homes, with room for EV charging, heat pumps, solar and future circuits.
Signs your panel needs attention
- Fuses instead of breakers, or a 60 or 100 amp main
- Rust, scorch marks or a crackling sound at the panel
- Plans for an EV charger, solar, a spa or central air
- Breakers that trip often or feel warm
- A panel with no open spaces, or doubled-up wires on one breaker

Bay Area households are adding load quickly: EV chargers, heat pump water heaters, induction ranges and home batteries. Older 100-amp panels in Mountain View often can't absorb that without a load calculation and, sometimes, an upgrade. Wind-driven safety shutoffs in the hills also make backup power a common request.

Electrical Panel Upgrade pricing in Mountain View, CA
Electrical panel upgrade cost in Mountain View depends on the amperage, whether the service is overhead or underground, where the meter sits, and what the utility and building department require. A like-for-like panel swap is at the low end; relocating the service or upgrading 100 amp to 200 amp with new grounding costs more. We inspect the existing setup and give you a written, itemized price.

Electrical Panel Upgrade questions from Mountain View customers
My panel is an older brand people warn about. Should I replace it?
Some older panel designs have breakers that can fail to trip. If yours is one of them, or shows heat damage, replacement is the safe choice. We'll open it and show you what we find.
Can you add a subpanel instead?
If the main service has spare capacity but no spare slots, a subpanel is often the cheaper answer. If the service itself is undersized, a subpanel will not help. See dedicated circuits and EV charger installation for common reasons to upgrade.
How long will my power be off?
For most panel upgrades in Mountain View the power is off for one working day, typically four to eight hours. We schedule the utility disconnect and reconnect so the outage is as short as possible.
Do I need 200 amps?
If you plan to add an EV charger, electric heat pump, induction range or solar, usually yes. We run a load calculation on your property so the decision is based on numbers, not a sales pitch.
In customers' words
After a surge took out our garage door opener and a TV, they installed a whole house protector at the panel. Quick job, clear price, no upsell.
Our old 100 amp panel tripped every time the AC and dryer ran together. Bayshore quoted the 200 amp upgrade on the spot, handled the permit and had us back on by late afternoon.
We needed new circuits and lighting before opening our shop. Bayshore worked around our contractor's schedule and the inspection passed the first time.
