Product Overview

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.

Is there a flush mount version of this device? My panel is flush mount in the mud room.

A good Electrician can make a small notch or hole in the sheetrock or plaster wall, and bring the unit wiring past the flush mounted cover, allowing the PowerBack Utility Power Return Alert unit to be mounted to the wall.

Is it possible to extend the wire? My main panel is outside and I need to run the alarm unit inside.

No. The lead that senses current is a predetermined length.

When I initially hook this device up under normal power conditions, will it immediately alert? -- Yes, if you flip the switch to turn it on if there is power it will sound its buzzer..... its LOUD too.... so very easy to see if you have it installed correctly.... the install is VERY simple... wrap the inductive coil around one of the utility feed to the main 100/200amp breaker and connect to the common rail.... and then mount the device in a punch out hole on the side of the panel.... unscrewing the panel cover took longer than the install!

Do i need an electrician to install this?

Asked by Suzer November 1, 2017

Yes, definitely! The wiring for this unit gets connected inside the Main Electrical Panel. Anytime there is a need to go inside your Main Electrical Panel, it is extremely dangerous for a non-electrician to do so! I can't stress this enough. If you don't know what you're doing, and you touch the wrong thing inside that panel box, even for the briefest moment, you could get electrocuted. This is no joking matter. Only Licensed Electricians should do any work inside the Main Electrical Panel. Period!

Connecting device is quite simple. I used zip ties to secure the lead to one of the 2 hot wires coming in from the power company. Sound is plenty loud; I could hear from inside house furthest point to device in garage. Mounted right above power panel. Used wall plate to conceal wiring and double face tape to adhere device to wall plate for "cosmetic appearance". Wish I ordered sooner since I connect my power generator directly to power panel through double breakers.

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.

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.

So your generator doesn’t run for no reason!

Easy to install and works as described! Got this so it would warn me when the Grid power was back so that the generator doesn’t run if it doesn’t have to .

Installation was easy and went quickly. It doesn't have a self test feature so it's hard to know if it's going to work until we have an actual power outage.

A good simple way to know if commercial power has returned while house is operating on generator. The audible alarm could be a little louder. The installation was simple.

Good product overall. It was relatively easy to wire and the instructions were clear. The only downside is that the threads are plastic and the brass lock ring does not screw on easy. Trying to tighten the lock ring in the congested panel was pretty difficult. I ended up have to force it on with a pair of pliers and definitely cross threaded it. I don’t plan to take it out so I guess it doesn’t matter but if I ever want to remove it I’m going to have to break the plastic case. A larger plastic lock ring would be better so you could tighten it by hand and just snug it up with pliers at the end. It is very loud when the alarms sounds.
