What we handle: Generator Installation in Pasadena

Bayshore Electrical Services & Design installs whole house generators and portable generator connections across Pasadena and Los Angeles County. As your backup generator electrician we size the system by measured load, so you are not sold more generator than the property needs.

Whole house generator installation

Air-cooled and liquid-cooled standby units sized to run the entire home or selected essential circuits.

Standby generator installation

Automatic transfer switch, pad, electrical connection and startup testing, coordinated with your gas or propane supplier.

Generac installation

Installation of Generac and other major standby brands, including load-shedding modules for large appliances.

Transfer switches and interlock kits

Manual transfer switches, panel interlocks and power inlets for safe portable generator use.

Generator maintenance and repair

Battery, oil and filter service, exercise checks and troubleshooting when a unit fails to start or transfer.

Critical-load subpanels

A separate panel for the circuits that matter most, so a smaller generator can cover them.

A generator makes sense if

  • You currently run extension cords from a portable generator
  • Outages or safety shutoffs hit your area more than once a year
  • You rely on a well pump, sump pump or medical equipment
  • You work from home or run a business from the property
  • You've lost a freezer full of food before

Generator Installation across Pasadena and Los Angeles County

EV charging, ADUs, central air added to older homes and all-electric remodels are driving panel upgrades across the Los Angeles area. In Pasadena, the main question is usually capacity: whether the existing service can carry the new load or needs to move to 200 amps.

In Pasadena we regularly work in Bungalow Heaven, Madison Heights, Hastings Ranch, South Lake, Linda Vista and Old Pasadena. Our generator installation service also covers nearby San Marino, South Pasadena, Altadena, San Gabriel, Alhambra and Sierra Madre. ZIP codes served in Pasadena include 91104, 91105, 91106, 91107, 91109, 91110, 91114, 91115, 91116, 91117 and more.

Generator Installation pricing in Pasadena, CA

Whole house generator installation cost in Pasadena depends on generator size, fuel type, distance from the gas meter and electrical panel, and local permit requirements. A portable generator inlet with an interlock is the budget option; an automatic standby system costs more and does far more. We measure your loads and quote both ways if you want to compare.

How a visit works

  1. Call (888) 633-7804 for a site visitWe look at the existing system, listen to what you need and take measurements.
  2. Load calculation and written quoteYou get an itemized scope and price, with options where there is more than one good way to do it.
  3. Permits and schedulingWe file the permit, coordinate with the utility or other trades and set dates that work for you.
  4. Installation and inspectionThe work is completed, tested, inspected where required and explained to you before we close out.

Common questions about generator installation in Pasadena

Can I just plug a portable generator into an outlet?

No. Backfeeding through an outlet is dangerous for you and for utility crews. A transfer switch or interlock with a proper inlet is the safe, legal way to connect a portable generator.

Do generators need permits?

Standby generators need electrical and usually plumbing or mechanical permits, plus placement that meets clearance rules. We handle the applications and inspections.

Generator or battery backup?

Generators run as long as they have fuel; batteries are silent and pair well with solar. Compare the two on our solar and battery backup page, and consider whole house surge protection either way.

What size generator do I need?

It depends on what you want to run. We add up starting and running loads for your essentials or your whole property in Pasadena, then recommend the smallest unit that covers them comfortably.

From recent customers

After two long outages we had a standby generator put in. They sized it properly instead of pushing the biggest unit, and showed us how the transfer switch works.

Twelve recessed lights and two dimmers in the living room, done in a day with no patching needed. The layout advice alone was worth the call.

Tom and Linda W.Recessed lighting

We needed new circuits and lighting before opening our shop. Bayshore worked around our contractor's schedule and the inspection passed the first time.
