Standby generators are used to provide backup power in the event of a power outage. They are typically composed of a generator, a flywheel, and a motor. When determining the size and power of a standby generator, the connected load must be taken into account. Generally, the connected load should be about 60% of the rated load. The generator must also be designed to provide enough power for the prime mover to operate properly. Secondary distribution takes care of feed-in to the network.
Sizes are based on their electrical output
Most people underestimate how much power they need and purchase a generator that is too small. This can cause a generator to overwork itself and may even cause damage. Likewise, buying too large a generator will result in the cost of running it being more than you need to spend. To buy the right size, it is important to consult a professional.
The electrical output of a standby generator determines its size. To calculate the right size for your home, first figure out how many appliances you use in your home. You can do this by adding up the wattages of these appliances. Keep in mind, however, that surge watts will throw off your calculation.
In addition to critical circuits, you can add convenience circuits to your generator. Adding convenience circuits increases the size and cost of the generator. If extended power outages are common in your area, you may want to consider buying a smaller generator that can accommodate the circuits you need. However, careful choices will minimize the size of your generator and reduce the cost. You should make a list of all the devices you need to power and divide them into two categories: convenience circuits and critical circuits.
In addition to their electrical output, standby generators are classified according to their size. Typically, standby generators fall into three categories: industrial, commercial, and residential. Residential generators operate on single electrical phase while commercial and industrial generators use three electrical phases. The last category, emergency generators, serve specific loads and are usually required by code. In addition to code requirements, they must meet strict safety guidelines.
