When 100 Amps Stops Being Enough
Service panel upgrades across Dixon: tired 100A services taken to 200A, fuse boxes retired, ranch and shop subpanels fed properly, PG&E scheduled, permits pulled and inspected before we pack up.

Electrical problems usually aren’t simple. A main breaker that gives up on the hottest afternoon of July, lights that sag every time the condenser starts, a charger that never quite fills overnight: those are symptoms, and reading them is the actual work. In Dixon the cause is almost always the same story told a few different ways. The house was built for a load nobody has asked it to carry since. Summers out here run long and dry, air conditioning is not optional, and a condenser sized for a Central Valley August is a serious continuous draw all by itself. Stack a heat pump, a car charger, or a shop full of tools on top of that, and a 100 amp service runs out of headroom well before anybody planned for it to.
Towers EC handles service work in Dixon from the Vacaville shop, the next town over on I-80. Master Electrician, CA Lic. 847255, thirty-plus years on the tools, Navy-trained before any of that. The person who scopes your panel is the person who installs it. Call (707) 803-6332 or tell us what the main says and we will read the service before anyone talks numbers.
Summer Heat Is The Real Driver
Cooling load out here is not a shoulder-season afterthought. A condenser running most of the day for months, plus an attic full of ductwork fighting it, is a standing demand that eats whatever slack an old service had left. That is the honest reason most Dixon panels get pushed over.
Power That Has To Travel
On the farmland edge, the panel is rarely the last stop. Barns, shops, well houses, and detached garages sit a long way off, and a feeder run at that distance has voltage drop to answer for. Sizing the service means sizing for where the power ends up, not where it starts.
Pumps Are Not Ordinary Loads
Well and irrigation motors pull hard on startup and pull it repeatedly through the season. A service already tight on capacity feels every one of those starts. If a pump shares a panel with a house that has grown, the load calculation usually tells a story the homeowner already suspected.
Equipment That Aged Out
Older housing here carries its share of small fuse panels and mid-century gear, including Zinsco and Federal Pacific equipment. Those brands are documented across the trade for breakers that stay closed on a fault. That is a replacement item, not something to nurse along another decade.
What A Service Change Day Looks Like
There is a utility and an inspector inside this job, so the order matters. Here is how we sequence it, so nothing about the schedule lands on you sideways.
We calculate before we quote
We total the real demand of the property, then add what you are planning: cooling, heat pump, charger, shop, well, ADU. The number decides whether this is a 200 amp service change or whether reorganizing and adding a subpanel gets you there with far less disruption. We would rather hand you the smaller answer than sell you a service you do not need.
We read the whole service path
Panel, meter base, mast, weatherhead, and the grounding and bonding underneath all of it. On older Dixon houses the grounding electrode is regularly the piece nobody has touched since the place was built, and a code-correct upgrade brings that current too. The box on the wall is the visible part, not the whole job.
Then we size for what is downstream
This is where rural property differs from a house in town, and it is where a lot of upgrades come up short. If a barn, a shop, a well house, or a detached garage is going to be fed off this service, the feeder distance belongs in the plan from the beginning. Voltage drop over a long run is not a technicality, it is what runs motors hot and shortens their lives, and the fix is conductor size decided at scope time rather than discovered afterward. We would rather set a service and a feeder that carry the whole property comfortably than watch you outgrow a brand new panel by the second summer.
PG&E and the right permit desk get booked
Pulling the meter takes a utility disconnect and reconnect, and the work takes a permit under our license. Inside the city limit that permit is the City of Dixon, and out in the unincorporated farmland it is Solano County, so we confirm which desk owns your address before filing. Then we stage the install behind both appointments so your power is out for one working day instead of a stretch of them. You are not the one on hold.
Set it, label it, get it signed
New panel set, circuits landed and labeled so the next person can actually read it, grounding proven, cover on straight. Then the inspector signs it off and the permit closes. That signed record is what protects you at resale and keeps the insurance conversation short. Our installation labor carries a lifetime warranty.
Straight Answers Before You Commit
How do I know whether my Dixon house needs 200 amps or just a subpanel?
A load calculation decides it, not a guess from the driveway. We total the actual demand of the house and add whatever you are planning next. If the number still fits under your existing service, a subpanel gives you slots for a lot less disruption. If it does not fit, no subpanel in the world creates amps that are not there, and the service itself has to grow.
Does my panel permit go through the City of Dixon or through Solano County?
It depends on which side of the city limit you sit on. Property inside town permits through the City of Dixon. Property out in the unincorporated farmland permits through Solano County. We confirm which one applies before we file anything, pull it under CA Lic. 847255, and keep the job open until an inspector signs it off.
Why does my AC make the lights dim every time it starts?
A condenser pulls a hard inrush when the compressor kicks in, and a dim is the whole service flinching under it. On a thin or tired service that is a symptom worth reading rather than living with. Sometimes it is a loose connection at the lugs, sometimes it is a service that has simply run out of room. We measure it instead of guessing.
Can you feed a barn, shop, or well from the new panel?
Yes, and on rural Dixon property that is usually half the reason for the job. A detached building wants its own subpanel and a feeder sized for the distance, because voltage drop over a long run is real and it is what cooks motors. We size the service to carry the outbuildings rather than leaving you short the first summer.
How long will my power be out during the service change?
One working day in most cases. The meter has to come off, so PG&E disconnects and reconnects, and we book that appointment and stage the work behind it. If your meter location or the drop makes the day longer, you hear that from us while we are scoping it, not while your refrigerator is warming up.
Do you replace Zinsco and Federal Pacific panels?
Yes, and we recommend it plainly. Both are documented across the trade for breakers that can stay closed during a fault, which defeats the one job a breaker has. There is no repair for that condition, only replacement. We set a modern panel sized to your real load, permitted and inspected, with a lifetime warranty on our installation labor.
Panel work rarely arrives by itself. If the upgrade is clearing the way for something else, we also handle new circuits and installation work in Dixon, standby generator systems for the outages that take the well down with them, and lighting work inside and out. When the trouble is a fault rather than a capacity problem, that is repair and diagnosis. You can see how we leave a panel in our recent electrical work.
Size It Once, Properly
Tell us the panel brand and the amperage stamped on the main, or just tell us what you are trying to add before summer. We come out, run the calculation, walk the service path, and put the scope in writing at no obligation. Three decades of showing up and doing the job right, for families and operators who depend on that work every day. Happy customers are the only reputation worth having.
Everything else we cover in town and out on the farmland is on the Dixon service page.
