Steve Torres built power infrastructure for early internet server rooms , facilities where a power failure meant real financial and operational consequences. That background in mission-critical power systems is what Towers EC brings to commercial and high-demand residential generator installations. We design the system: generator sizing, transfer switch type, critical load segregation, neutral bonding, test procedures. Then we build it and prove it works.
A power system is a design question before it is an equipment question. The first decision is whether you are backing up the whole panel or only the loads that matter, because that one choice changes the generator size, the transfer switch, and the cost. Backing up everything means a much larger unit that idles most of the time carrying loads you do not need during an outage. Backing up the essential circuits means a smaller, cheaper unit and a transfer scheme that powers the refrigerator, the furnace, well pump, and key lighting while the rest of the panel stays dark. We walk your panel, map what is actually on it, and design around the way the building really runs.
Talk To The Master Electrician- System designed before priced: We spec the complete system in writing so you know exactly what you’re getting.
- Critical load segregated from non-critical: Generator carries what it needs to carry. Not the whole panel at once.
- Full documentation provided: As-built drawings, panel schedule, transfer test results, operation instructions.
- Load bank tested: Every commercial system is tested at full rated load before we close the job.
What We Do
Every service we provide comes with the same master electrician standard , CA Lic. 847255, lifetime warranty on install labor, permits pulled, inspections passed.
Commercial Generator Systems
Business continuity power for offices, data rooms, retail, medical facilities.
Critical Load Segregation
We wire the system so the generator carries the right loads, not everything at once.
Manual and Automatic Transfer Systems
Correct for the application. Spec’d, installed, and tested.
Load Management Panels
Smart load management to prevent generator overload during automatic transfer.
UPS and Generator Integration
Bridge power for equipment that can’t tolerate even a brief transfer delay.
System Documentation
As-built drawings, load schedule, transfer procedure, test results. You get the full package.
Designing The Whole System, Not Just Sizing A Generator
Whole-home and commercial backup is an engineering problem. The generator is one component in a system that also has to manage how load comes on, how the transfer happens, and what stays running.
Whole-panel vs essential circuits
The honest answer for most homes is that you do not need to back up the entire panel, and a load-managed essential-circuit design gives you the same comfort during an outage for less generator and less fuel. For a commercial building the calculus is different: a medical office, a server room, or refrigerated retail may genuinely need the whole service backed up. We size the system to the real requirement, and we tell you when a smaller, smarter design does the job a bigger one was quoted for.
Automatic transfer switch logic
An automatic transfer switch is where the system thinks. It watches utility power, starts the generator on a loss, waits for the unit to stabilize, then moves the load over, and it reverses all of that cleanly when the grid comes back. The settings on that sequence, the delays and the transition type, are not defaults you leave alone; they are tuned to the equipment downstream. On a system with sensitive loads we set it so the transfer is controlled, not a hard slam.
Load management and big motor starts
Air conditioners, well pumps, and other motors pull a large surge the instant they start, far above their running draw. A power system that ignores that gets tripped by its own loads the first time the compressor kicks on during an outage. We use load-management panels that stage the big loads so they do not all hit the generator at once, which lets a correctly sized unit carry a building that a naive design would have stalled.
Commercial backup and code
Commercial work brings three-phase power, larger units, seismic anchoring, and standards like NFPA 110 for emergency and standby systems. It also brings real documentation and commissioning expectations. We have built these systems from scratch, so the permit, the inspection, the load-bank test, and the as-built package are part of the job, not an afterthought. Want a free scope on a commercial backup system? Call and we will assess the service and the load before anyone talks equipment.
When You Need A Designed System, Not Just A Generator
A power system is the right call when an outage costs you more than comfort. A medical office with refrigerated samples, a small data room, a restaurant with walk-in coolers, a winery managing temperature on a tank: for these, downtime is inventory and revenue walking out the door, and the backup has to be engineered to the building, not picked off a spec sheet. The same is true for a high-demand home with a well, a pool, multiple HVAC zones, and a home office that cannot go dark.
Designing it starts with the panel, not the catalog. We map what is actually on your service, separate the loads that have to stay alive from the ones that can wait, and size the generator and transfer scheme around that reality. That work is what keeps you from overbuying a unit twice the size you need, or worse, from installing one that trips itself the first time the air conditioning and the well pump start together.
Commercial backup carries obligations a residential install does not. Three-phase service, seismic anchoring for California, and standards like NFPA 110 governing emergency and standby systems all shape the design and the inspection. The transfer switch logic, the load-management staging, and the documentation are not extras here, they are how the building passes and how the next electrician understands the system. We provide the as-built drawings, the load schedule, the transfer test results, and the operating procedure as part of the job.
Steve Torres built power infrastructure for the server rooms behind the early internet, where a power event had financial and operational consequences and the systems were engineered to never blink. That is the standard Towers EC brings to a commercial or high-demand residential power system: designed first, priced against the design, load-bank tested before signoff, and backed by a master license and lifetime warranty on the install labor.

Frequently Asked Questions
What is critical load segregation?
It means wiring the transfer switch so the generator only powers the loads that are truly critical , refrigeration, life safety, data equipment, HVAC. Non-critical loads stay dark during an outage. This lets a smaller generator handle a larger building’s critical functions.
What documentation do I get after a commercial generator installation?
We provide: as-built wiring diagram, panel load schedule, ATS settings, transfer sequence test results, a plain-language operating procedure, and the inspection sign-off. You get a complete file.
What is a load bank test?
A load bank is a piece of test equipment that simulates electrical load on the generator. We connect it and run the generator at 100% rated load for a sustained period to verify it performs as specified. Important for commercial systems , you want to know it works before you need it.
Can you service an existing generator system?
We inspect and test existing transfer switch systems, diagnose transfer failures, and can often repair or upgrade components without full replacement. Call (707) 803-6332 to describe the system and we’ll tell you if we can work on it.
How is commercial generator installation different from residential?
Commercial systems typically involve three-phase power, larger generators, more complex load segregation, seismic anchoring, compliance with NFPA 110, and more thorough commissioning and documentation requirements. We’ve built these systems from scratch and understand what commercial occupancies require.
