Is the Power back on?

[ptonsparky]

Customer wants to know when the POCO power comes back on and he found and directed me to a Reliance THP 108.
Seems like it should work.

Have any of you used it? Any cons?

I don’t think it would work with a main interlock because it would be on the service side of the breaker.

It has an Antenna, their word, that wraps around an incoming hot. No direct connection required.

It is basically a non contact voltage sensor coupled to the main wires. Since it is measuring through the normal insulation you don't need to worry about making an electrical connection before the main.

I installed one, not difficult at all. Don't recall how loud it was, don't recall its battery requirements.

Have you used it since it was installed?

 

[winnie]

It is at a friends house; I will ask.

The unit was used once since installed.

It has a switch on the side; you have to turn it on when switching over to the generator. It will then sound when mains comes back on.

The location was in the far corner basement of a wood framed somewhat sprawling structure. It could be heard over half of the first floor.

(Reports from the friends using it, not direct experience.)

Excellent. Thank you.

That's a skookum little unit for under $50... Too bad it doesn't have a relay output that you could wire to something else, but being powered from a 9V battery, I can see why.

Relay powered by utility side of transfer switch. Make it operate a "kill switch" for the generator when utility is active, put a delay on it if you want to prove utility for certain time period first, override switch in the kill circuit if you want to run generator for any reason when utility is active.

Loss of generator power will get owner/occupant attention and you can have a visual indicator of some sort at transfer switch or generator to indicate utility is on.

Isn’t that what the green light on automatic transfer switches do now?.

green light indicates, but doesn't control anything.
