I asked my electrician to supply and fit one of these in the meter box, so I could use a genny to power up the house on occasions. Alright, but the switch price alone is $700. "Gotta be approved by the utility".
I understand it has to be "break before make", and able to handle house current, but that's too dear for a simple switch, surely? Anyone struck this hurdle before? I'm not inclined to get one at that price.

This would be the switch you need. I don't know how much it costs but I don't think it could be anywhere near &700.

Thanks Reiner. The price is on the website - $440 inc GST.
It's an electronic automatic switch, with a 2 year warranty.
I was hoping for a fully manual, maybe knife switch - something that would see me out!

All you need in my opinion is two contactors. One runs of the mains and the other one of the generator. Main power goes contactor falls shut and starts the generator but disconnects from the main at the same time.
You could have a time delay of a few seconds to make sure the mains power is disconnected well before the generator starts.
I might have overlooked something but that should work a lot cheaper and still being safe.

Sounds interesting. I'll put it to my electrician. Thanks again Reiner.
By the way, I don't need quick changeover action - just deliberate, safe selection of either but not both supplies. The danger is that my gen power could feed back up the utility's line, and be a danger to someone who might be working on it, and who thinks it's not a live line.

That's why you need a contactor on the generators line as well he closes when the generator produces power and opens the line to the net so the power can't go backwards. If your electrician still tries to sell you a $700 switch find one a bit smarter.

Thanks Lance. Getting closer, but that's only a 20A switch. I think I need more like 80 amp capacity.

They advertised here when we had problem with power a few months back... $400 for a switch fitted. You can just basically plug your generator into your box and away you go..

Regards, Ari :)

Do you have specs, or the make/model of the switch?
Maybe a photo?

Thanks,
Jordan
