The primary power source fluctuates and fails.It triggers the alternate generator (which is prone to have more limited fuel and capacity) only when the power line stops sending signals. As a rule of thumb, the switch always tends to default to the utility connection. The “control logic” (the “brain”) implemented in the ATS system monitors the voltage and frequency of the energy sources connected to the device. It’s hard to deny some of the benefits of manual transfer switches (primarily as it concerns cost-effectiveness), but, alas, these will not save you from damages inflicted by sudden electricity cuts, hence the importance of having a reliable automated mechanism. Notwithstanding, as long as you have a working replacement for your utility provider, an ATS removes the need to manually activate it (while it also gives you the option to do it yourself, all things considered). Needless to say, an automatic transfer switch does not cover the need for an alternative power generator. Whenever you experience brownouts or energy shortages, you’d want a dependable failsafe that can get you through the most demanding and stressful situations, This is a particularly handy asset for people who live in areas where the power grid is vulnerable to failure. You may want to install an Automatic Transfer Switch on your premises if you need a non-stop power-yielding mechanism that can operate without your input. Nevertheless, it will only work if installed and programmed correctly by qualified personnel or knowledgeable individuals. For that reason, it’s capable of operating without human intervention. It bears stressing that the gadget is controlled via a dedicated automatic controller. Others allow for short second-long delays (open transition ATS) or even to run two sources in parallel if you require a power boost (soft loading ATS).įurthermore, you may install your ATS for a myriad of arrangements, whether the setup comprises two power sources (utility-generator, utility-utility, and generator-generator) or three (utility-generator-generator and utility-utility-generator) in more critical sectors. Some ATS systems are specifically designed to feed uninterrupted power (closed transition ATS) in situations where even short blackouts could prove disastrous for adequate service provision (e.g., healthcare). Nevertheless, the one you choose to install would have to be suitable for your daily energy needs. You’ll find a wide range of ATS panels on the market. This guarantees that your appliances will not shut down whenever there is a power outage in your area. When shopping for an automatic transfer switch, you need to pick the right size, voltage and whether the switch should be weather-resistant for outdoor use or not.An Automatic Transfer Switch (ATS) is a “smart” microprocessor-driven instrument that, as its name suggests, shifts from one power source to another for continuous energy delivery. When the link is broken between the two wires, the generator understands it should turn off.Īurora Generators use generator controllers that are compatible with all two-wire start type transfer switches. Typically the ATS signals a generator to start by closing a two-wire connection. It is the job of an automatic transfer switch to tell the generator when it is needed. It is usually at the top of your electrical panel, and it has a number on it representing the size of the circuit breaker. You can often tell what size your home needs by looking at the main circuit breaker for your electrical panel. Most homes are 200 or 100 amps, and large homes may be as much as 400 amps. They are typically matched to the size of electrical service you are provided with by the utility company. Transfer switches come in different sizes. ![]() Many business and commercial applications use three-phase power, 208,480 or 600 volts. Homes in North America use single-phase 120/240 Volt transfer switches. It also prevents dangerous back-feeding of energy to the mal utility that can seriously injure or kill someone working on it during an outage. Once the generator is producing power, it safely disconnects your standard utility power and takes it from your generator instead. When needed, the ATS tells the generator to start-up automatically. An automatic transfer switch (ATS) monitors utility power for any trouble or failure. To safely connect a generator to a home or business, you use a Transfer Switch.
