What is an automatic transfer switch?
An automatic transfer switch, or ATS, senses a loss of power to an electrical panel and shuts down the motherboard by engaging backup power lines. You can do everything manually and the reverse will be done once power is restored.
Interlock and transfer switch:
An interlock device is similar to a transfer switch in that the device helps you manage the operation of your electrical panel and backup generator panel. Interlocks ensure that the electrical circuit breaker and generator circuit breaker are never operated at the same time. Therefore, it ensures safety and prevents any dangerous feedback that may occur.
Before deciding which system is best for your application, you should better understand your needs. You should consider the type of generator you install, whether it is a backup generator or a portable generator. You should consider size, electrical loads, outage duration and frequency, occupant needs, and on-site operator availability.
When to use interlocks?
Interlocking systems are less complex and less expensive than automated conversion spaces. Many people use it for residential and small commercial purposes. It is more suitable for places that do not require continuous power supply and is easy to operate. However, you need proper training to understand how it works. There is also additional power management where you need to turn off the circuit breaker once the generator capacity is exceeded. We’ll detail the differences between interlock switches and transfer switches for portable generators below.
When to use a transfer switch?
Residential automatic transfer switches are suitable for situations where automatic operation of the power supply is required. You can often find it in commercial buildings that require back-up power for safety. Additionally, it complies with building codes and state election regulations. You can install it in your home even if your home has frequent power outages.
Both are ATS automatic transfer switches and the interlocks work the same way. However, they operate differently. You can use them for a variety of applications. Interlocks are more suitable for residential use and where there are fewer power outages. On the other hand, you can use automatic transfer switches for commercial purposes and large apartments.
If you have a fully automatic system that requires no supervision, you must choose an ATS transfer switch. It can also serve all commercial or industrial purposes with the help of automatic switches as they require constant power. Both of these devices are required if your home has a backup generator. You’ll also need it for any building with backup power from a transfer switch.
How do transfer switches work with portable generators?
Let’s say you forgot to install a transfer switch and instead connected your portable generator directly to the electrical panel. In this case, it can cause appliances to burn out, endanger utility workers who may be working on the power lines, and ultimately damage your generator.
Transfer switches quickly power whatever appliance you need, whether it’s a refrigerator, boiler, or other appliance. Power can reach these devices through the generator or the utility, but not both. The automatic transfer switch will work with the help of a set of dedicated switches.
With a transfer switch, you need to make a connection by plugging one end of the wire into the portable generator and the other end into a specialized box connected to the transfer switch.
How do interlocks work with portable generators?
Many third-party manufacturers and service panel manufacturers use interlocking devices for small connectors. Each unit is only available on a specific panel model, but they all work the same way. You can connect them to a portable generator’s service panel without the need for a transfer switch. Therefore, they eliminate the risk of direct connections. You must install the interlock with the help of an electrician.
Once installed, the interlock will cover the service panel. Therefore, you will not be able to turn it on while the generator is running. When mains power is restored, you will be able to slide the interlock back into its original position. Therefore, electricity will only flow in one direction. This option is a more manual option than an automatic transfer switch, but it is less expensive than purchasing and installing an automatic transfer switch.
FAQs
Can I install a generator interlock kit myself?
While interlock kits are simpler, it is highly recommended to hire a licensed electrician to ensure it meets local building codes and prevents backfeeding.
Is an ATS better than an Interlock for sensitive electronics?
Yes. An ATS provides a faster, more seamless transition, which is crucial for protecting sensitive equipment like servers and medical devices.
Is a generator interlock legal?
In most regions, interlock kits are legal as long as they are UL-listed and installed correctly according to NEC standards.
