"We called Dalcon Electric when a car struck a power line outside of our building and knocked out the electricity to our building. They were quick to respond in an emergency, courteous and professional. They helped us get our business back on track in a pinch. Then, we hired Dalcon to replace all 53 outdated outlets in our building. Dave and his crew (Jack and Billy) completed this efficiently and with minimal disruption to our business. When we needed to install emergency exit signs, Dalcon provided by far, the best quote for the work to be done compared to many other handymen we had considered. Jack and Billy installed our emergency signs and cleaned up the area where they had worked leaving it just as, if not better than, how they found it. Everyone at Dalcon is courteous, prompt and responsive. Dave, the owner, came in person to our office to discuss each project to be done. Scheduling these projects was a breeze, Sarah and Suzanne in the office were very responsive and made sure our concerns were addressed. We scheduled the projects out over time, but when a sooner date became available, someone from Dalcon would call and ask if that time would work for us so we could have our projects completed sooner. We would definitely work with Dalcon Electric again."

"Los Gatos Electric provided a great turn key operation. Jim coordinated delivery of the replacement generator, also coordinated enlarging the cement pad and installation of the unit. He replaced my 25 year old generator with a Generac Generator. And hooked it up to the existing automatic switching panel which saved me time and money. Overall, I thought it was an excellent effort."

We work on anything from generators and lighting installation, to electric panel repair. Needless to say, our work has provided customers with electrifying satisfaction.

"Everything went fine with the exception of the fan install which was pretty tricky - we have some funky wiring done in the 80s by the old homeowner. Otherwise, great - Marcus got out to our house quickly and there were A LOT of lights/switches/exhaust fans to install which were taken care of quickly and at a reasonable price."

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.
