WHOLE HOUSE GENERATOR INSTALLATION GENERATOR
You have a second air conditioner and heating system for the upstairs, but this area of the home is not important to you while operating on generator power. the downstairs central air conditioning unit.kitchen receptacles and lights (including refrigerator/freezer).Let’s say you are looking for a budget-friendly installation of a “partial house generator.” You have one or two breaker panels, gas heat and hot water, and you’ve identified the following electrical circuits as “essential” while operating under generator power: When a generator is connected to all house circuits, the installation is referred to as a “ whole house generator installation.” Connecting only a few essential circuits, or “partial house generator”, can be an effective means of providing power to the essential electrical circuits most important to you, while saving on overall project costs. 20kW is enough to run most house receptacles, lights, and up to a 5-ton central air conditioner. If the range top is also gas, all the better. If your home is 2,500 square feet or less, a generator with 20kW should suit your backup power needs well, particularly if you have gas heat and hot water. If the generator you select will be connected to a breaker panel with a 100-Amp load center, then you will need a 100-Amp Automatic Transfer Switch. In the 20kW generator example, these are connected to a 200-Amp load center and, thus, come with a 200-Amp ATS. Make sure the size of the ATS matches the size of the load center it will be connected to. Most of these circuits do not require a large amount of power to keep them operational, but it’s important to consider the sum total of each of these loads when sizing a standby system.Ī very popular and “easy on the budget” generator is a “20kW” (20,000 Watts) model because they are air-cooled (as compared to “liquid-cooled”) and cost around $5,000.00, that's including the 200-Amp Automatic Transfer Switch (ATS). Examples of common essential circuits include the refrigerator/freezer, kitchen receptacles, a few light and receptacle circuits, the fan blower motor for gas heating equipment, the security system, garage door opener and, if you have them, water pumps and sump pumps. Keep in mind, a standby generator can be connected to all of your home’s electrical circuits or just a few “essential circuits”. See this Quick kW Guide of Common Household Appliances to gauge how much power you may need. A qualified generator installer can help you determine the proper generator size after calculating the anticipated electrical loads needed for desired backup power. Generators are sized in kW or kilowatts, so a 10kW generator will produce 10 kilowatts or 10,000 watts of power. Understand Kilowatts and Electrical Circuits to determine which size generator is best? It is best to consult a qualified installer to determine what size generator you need for reliable backup power for your home or business. Standby generators come in a wide variety of sizes, varying in cost from just under $2,000.00 to $20,000.00 and more.
