Product Overview

  • Install on a manual transfer panel or generator-ready load center
  • Includes lights for 'System Armed' and 'Low Battery' alerts
  • Backed by a 5-year limited warranty for your satisfaction
The PowerBack is intended to be installed on a manual transfer panel or generator-ready load center. During a power outage, when the main breaker has been turned off to allow the generator to provide emergency power to the panel, the PowerBack can be activated and will emit a pulsing 105dB alarm when the power outage ends and utility power is again available. The PowerBack installs in a 1/2 trade size knockout in the panel within 20 in. of one of the utility hot legs. It includes an eight-inch current sensing antennae at the end of a 22 in. jacked lead. When wrapped around one of the hot legs to the main circuit breaker, the antennae will detect the returning utility current and activate the sonic alert.
  • Lights for "System Armed" and "Low Battery"
  • 9 Volt battery not included

Do i need an electrician to install this?

Do i need an electrician to install this?
Asked by: Szr
No, not unless you feel uncomfortable in removing your breaker panel cover & carefully connecting 2 leads. One goes to the box neutral and the other just wraps around either hot leg of the main feed. Very easy.

How does the sound turn-off after it senses power?

How does the sound turn-off after it senses power?
Asked by: DW
You have to manually switch the unit off after the power returns. It's always in a standby mode until you switch it on after turning off the main breaker & powering up your generator.

Suggestion for an suitable enclosure for mounting to an outdoor main panel?

My panel is on the exterior of the house. I'm looking for a box I can mount to the bottom of the panel via one of the knock-outs that will enclose and protect the Powerback device from weather.
Asked by: bgeery
The unit doesn't appear to be water proof and I suppose you could enclose it in a plastic case but how would you here it from inside the house?

When will this item be back in stock?

Asked by: PGOGO
Suggest you purchase on-line via HomeDepot.com and pick-up at your local store. That's how I got mine, took about a week.

I mounted mine on the side of my breaker panel so that I could reach the on-off switch without having to use a ladder. Very simple to install with only having to connect a ground lead to the panel terminal and twisting the sensor lead to either of the hot feeder leads. The sensor lead should be tied to the main hot lead so that it won't unravel with a cable tie provided.

Rated 5 out of 5 by from Simple to install and does what it says For other reviews which say this is not loud enough I think they must have a high tolerance for loud noise. When I set this thing off the alarm blew my head off so I was suprised that many think that it is not loud enough to hear. Of course if you have a huge house and the panel is very far away I can see that it may be a problem hearing the alarm but you have to be realistic. I found this unit as loud as a smoke alarm. At least to me. Installation was a breeze and so far it seems to work. I won't know until the power actually goes off. But when the power is on this alarm sure does let you know. This product is exactly what I was looking for!

Rated 5 out of 5 by from Works as advertised! Unit works great. Wrap around hot leg with electrical tape. This gives a tight fit. Sonalert is loud and I can hear it well at all locations. Added benefit is a magnet is on the back of the unit so you can place it on the box if the box is recessed. Good pricepoint as well.

Rated 5 out of 5 by from Just what I needed, great price and product I recently back fed my load center with a generator hookup and interlock switch (also bought at home depot) and I had no idea how I was going to tell when the power came back. I didn't know these things even existed until I was buying the interlock switch and saw this under the "customers also bought ...." section. This thing works great, install it in a knockout, ground it and wrap the antenna around one of the main feeds and your done. When it's enabled it beeps when power's present. I've seen others say it isn't loud enough, but mine is extremely loud. Ear piercing in fact. The price was better then amazon and the product itself seems well built. What more could you want.

Rated 5 out of 5 by from Great Value ! Easy to install and works great. I did not have room to mount on top of the power panel as suggested due to all the wires, so I mounted mine on a 3/4" PVC LB that I mounted on the side of my power panel at a knockout within easy reach. When activated by a power return it is VERY LOUD and can be heard throughout the house. So loud it almost hurts while getting to it to turn it off. I used to watch for neighbor's lights to come back on, now I know immediately when I can switch back from the generator.

Rated 4 out of 5 by from Easy to install I recently purchased a portable generator which I backfed into my main breaker box. Thus I needed a method to let me know when utility power returned. This box appears to fulfill that need. I tested the box after installation by turning off the main CB in the panel and checked to see if the alarm would sound; it did. Installation is easy, but of course you need to be very careful of the 220VAC present in the panel. The 9V battery compartment is quite tight fitting, but I suspect I will not need to change the battery very often. While standing next to the alarm, it seemed very loud to me (almost ear-splitting). Note: The picture is not upside down; the box is installed on the bottom of my breaker panel since thats where the main line comes into the box.

Rated 5 out of 5 by from Does just what I needed I was looking for something like this for years, and now I've found it. Installation was a snap, though you do have to wrap the "antenna" wire quite tightly around the main feed wire. I added a couple of tie wraps and then wrapped the whole assembly in electrical tape to keep it closely coupled. If you have the antenna too loose, it will not alarm when the power comes back on. But other than the care needed in installation, I can't imagine a much better way to tell that the power has returned after an outage.
