What is a home standby generator?

A home standby generator is a backup power system that automatically supplies electricity to your home during a power outage. It is permanently installed outside your home and is designed to turn on within seconds of a power failure. It is powered by natural gas or propane and can provide enough electricity to power your entire home or just the essentials.

Why should you install a home standby generator?

  • Protection from Power Outages: A standby generator ensures that your home has power during an outage, which can be especially important if you have medical equipment that requires electricity or if you live in an area prone to natural disasters.
  • Increased Home Value: Installing a standby generator can increase the value of your home, making it a worthwhile investment.
  • Convenience: With a standby generator, you don't have to worry about running extension cords or setting up portable generators during a power outage.

What size generator do you need for your home?

Choosing the right size generator for your home is important to ensure that it can provide enough power during an outage. The size of the generator you need depends on several factors, including the size of your home, the number of appliances you want to power, and your budget.

Home standby generators come in a range of sizes, typically measured in kilowatts (kW). The size of a generator needed for a particular home will depend on the electrical load that needs to be supported during a power outage.

For small homes or essential circuits, a 7-10 kW generator may be sufficient. For larger homes, a 15-22 kW generator may be more appropriate. Some homes may require even larger generators, up to 45 kW or more, depending on the size of the home and the specific electrical demands.

It's important to consult with a qualified electrician to determine the appropriate size generator for your home based on your specific needs and electrical load.

I had a electrical panel relocation in my unit and was impressed with Rudy, everyone involved, and the whole process.

I was very impressed with your team, and especially Rudy who was so knowledgeable and provided the absolute best option with the least amount of disruption. He was professional, polite, patient and both he and Edgar worked very hard to accomplish this difficult task. They did not even take a break, and when it was all completed, they made sure to leave the space as clean as possible.

The insurance company for the condominium where I live required over 500 owners of individual apartments to replace their electrical boxes this year as a condition of renewing the condominium’s insurance policy next year. As part of the replacement, many owners had to move their electrical boxes in order to get a county permit for the replacement because the original electrical box location did not meet current electrical codes. We first called an electrical company who has done work for us in the past and they said that we would have to have kitchen cabinets taken off the wall before they could move and replace our electrical box. We then called Castro, who were recommended by many other residents of our building who had already had their electrical boxes moved and replaced, and they gave us an estimate that was significantly lower than the first contractor we talked to and that did not require us to remove cabinets from the wall. We signed a contract with Castro, they showed up as scheduled, ran the wires to move our electrical box location without removing any cabinets from the wall, and our new electrical box passed county permit inspection. Based upon this experience, I would definitely use Castro Electric again and I strongly recommend them to anyone who needs an electrician.
