Electrical Panel Upgrade in Monrovia, CA
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 If yours is full, outdated or only rated for 100 amps, adding an EV charger, air conditioning or an induction range can push it past what it was built for.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 Monrovia gives you the capacity and the breaker protection modern loads need.

EV charging, ADUs, central air added to older homes and all-electric remodels are driving panel upgrades across the Los Angeles area. In Monrovia, the main question is usually capacity: whether the existing service can carry the new load or needs to move to 200 amps.
Our electrical panel upgrade service also covers nearby Duarte, Arcadia, Sierra Madre, Temple City, Baldwin Park and El Monte. ZIP codes served: 91016, 91017.
Electrical Panel Upgrade pricing in Monrovia, CA
Electrical panel upgrade cost in Monrovia 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.

Monrovia electrical panel upgrade FAQs
How long will my power be off?
For most panel upgrades in Monrovia 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.
Is a permit required for a panel upgrade in Monrovia?
Yes. Panel and service upgrades require a permit and inspection, and the utility has to approve the reconnection. We handle all of it.
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.
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.
Three ceiling fans installed where there were only light fixtures before. They swapped in fan-rated boxes and balanced all three. Quiet and solid.
