Choosing a standby generator pad is an important step towards making sure that your power system remains reliable during a power outage. There are many different factors to consider when deciding what type of pad is best for your home, including the size of your home and your budget.
Pre-cast vs. poured concrete
Whether you are installing a standby generator for your home, office, or business, there are several choices available. One of the most important decisions is whether to use a pre-cast or poured concrete pad. Each type has its advantages and disadvantages. Choosing the right option for your specific situation can save you time, money, and headaches.
A pre-cast concrete pad will provide durability and longevity. It is made in a factory, which will ensure quality and consistency. It also saves time on installation. The pad is usually 3 inches to 4 inches thick, depending on the weight of the generator.
A poured concrete pad can also provide more stability. The pad is poured into place and may be secured to the building foundation with steel rebar. Some communities require poured concrete pads for home standby generators.
Using a poured concrete pad can make the installation of your generator easier. The process involves removing soil, leveling the area, and compacting it. The pad will also need to cure for a few days.
Determine the size
Whether you are considering a whole house backup generator or an emergency backup power system for your office building, you will need to determine the size of the standby generator pad. A properly sized pad will allow your technicians to work at a comfortable height without compromising the safety of your home or office.
Fortunately, there are many options to choose from. You can use a pre-cast concrete pad or opt for a custom pedestal. Alternatively, you can hire a licensed contractor to build a concrete pad as a base.
A good concrete pad is worth its weight in gold. If you decide to go with a pre-cast pad, make sure it is properly leveled before adding the generator. It is also a good idea to leave room for future expansion. A properly constructed pad will withstand the test of time.
The best way to determine the size of a standby generator pad is to measure the footprint of the unit you are considering. Many manufacturers recommend a minimum of 6-12 inches of clearance on all sides.
Adding standby generator pad vibration isolators to a generator set can help prevent vibrations from transmitting to the building structure. These vibration isolation pads are used to control resonant vibration and can be installed under machinery or metal panel enclosures.
A combination of pads and springs will reduce most vibrations. However, if the installation is quieter or requires a higher level of isolation, a second set of isolators may be required.
A spring-type isolator provides 95 percent isolation of vibration. The spring should be adjustable for deflection of at least three inches. Elastomeric isolators are also available. Elastomeric isolators have high resistance to shear loading and are especially effective at dampening high frequency vibrations.
The spring isolator should be recessed into the pad’s perimeter. A thin elastomeric pad can also be used between mating surfaces.
For larger multi-genset installations, a higher level of vibration attenuation is needed. This may require a seismic-qualified mount. In addition, the location of the installation may require a high shear rating.
Considerations when purchasing a generator
Choosing the right standby generator pad is important. It needs to be sturdy, stable, and properly designed to support your generator. You also need to consider your local building codes and regulations.
Most communities require poured concrete pads for home standby generators and central air conditioning units. Depending on the size of your generator and the area of your home, you may need a larger or smaller pad.
There are three types of pad for generators: pre-cast, custom, and made-on-site. A pre-cast pad is usually the cheapest concrete pad. It has a longer span length and is typically 3 to 4 inches thick. However, it is more expensive than a custom pad. The cost is also more expensive than a made-on-site pad.
The thickness of a concrete pad depends on the weight of your generator. The pad’s thickness is determined by dividing the generator’s weight by the pad’s surface area. If the pad is too thin, it can crack, resulting in legal and regulatory issues.
