Introduction
Have you ever been at a supermarket or office building during a power outage? Everything shuts off then, seconds later, big generators rumble to life and everything turns back on. It’s not magic, and there is nobody whose job it is to stand by some switches, waiting for an outage. This transition is made possible by a device called an automatic transfer switch (ATS). In this guide, we’ll get an overview of the ATS, how it works, and whether one can add value to your home life.
What is an Automatic Transfer Switch (ATS)?
An automatic transfer switch is like the conductor of a choir, except instead of tenor, soprano or bass sections, there is main power and backup. An ATS orchestrates a smooth transition between your main power source (usually the electrical grid) and your backup power supply (like a generator or solar power system). Its primary function is to ensure a continuous and uninterrupted power supply during outages.
How Does an ATS Work?*
1. Constant Vigilance:
An ATS is always on guard, monitoring the electricity flowing from your main power source. As long as everything is running smoothly, the ATS allows the electricity to flow from the grid to your home without any interference.
2. Reaction During Outages:
The important part happens when your main power source fails, as is common during storms, load shedding or planned maintenance. The ATS, senses the interruption, then automatically redirects the circuitry so that electricity flows from the backup source. This temporarily cuts off your house from the grid while backup power handles your lights and appliances.
3. Time Delay Considerations:
While the switch is fast, there’s a short delay involved in the transition. This is usually in the range of seconds, so you might notice a brief flicker in the lights during the switch. However, this is a small price to pay for uninterrupted whole-house power.
4. Manual Activation (Setup Dependents):
In some cases, especially with simpler setups, the backup source might require manual activation. For example a petrol generator may requite manual starting. That means the ATS will switch over to the backup circuit but you will need to physically start the generator (and turn it off later) yourself. More advanced setups like a solar power system can eliminate the need for manual intervention.
One of the primary applications of an ATS is to control backup power for an entire house. When the main power source fails, the ATS ensures a swift transition to the backup supply, providing supply to every plug, light and accessory in the house. This removes the need to, for example, plug a long extension cord into the backup device to reach your appliances. It also means you can use your built-in overhead lights like normal during an outage.
ATS Installation: DIY or Professional Help?
An important question; is installing an ATS a DIY project or a task for a qualified electrician? The answer: it depends. While some homeowners with electrical expertise might be comfortable with the installation, it’s highly recommended to enlist the services of a qualified electrician for several reasons:
1. Expertise
Installing an ATS involves working with your home’s distribution board (DB) and wiring, which requires a good understanding of electrical systems. A qualified electrician brings the necessary expertise to ensure a safe and reliable installation.
2. Compliance:
Installing an ATS requires some modification to your house’s wiring (at the DB). Therefore, any work must comply with Eswatini electrical codes and regulations. A professional electrician is well-versed in these requirements, ensuring that the installation is not only functional but also meets all safety and legal standards.
3. Warranty and Insurance:
Component often require proof that the device was installed by qualified personnel before accepting a warranty claim, The assumption is that an unqualified installer may have inadvertently damaged the device through lack of knowledge. Thus, hiring an electrical contractor accredited by the Construction Industry Council (CIC) can provide peace of mind in case anything goes wrong. Additionally, insurance companies may require professional installation to validate coverage for any potential damages or accidents related to the electrical system.
Conclusion
An automatic transfer switch is a silent guardian, ensuring uninterrupted power supply during unexpected outages. While it offers convenience and reliability, the installation process is best entrusted to a qualified electrician for safety, compliance, and peace of mind.
