Looking at the original Amazon item the FAQ's state it is not CE marked so what other testing has it been through

 

[UNG]

I did find on Amazon another auto change over switch that claims to be compliant with another British standard.

I do howver suspect it also may be of Chinese origin.

It claims compliance but has it actually got the appropriate certification stating it complies with the standard

 

[binky]

The item I listed is £70.

China can make good products, as you say virtually everything we buy has Chinese content, but, they need supervising to get the standards right.

As for the other switch you have found, I see no CE markings or any claim to comply with relevant standards. It also has the same weak looking switch that broke on the gadget I bought.

It means it's good that it's made of fire resistant plastic

Below is a link to a manual change over switch, note the difference in size, coz it's not Chinese tat. Look at the terminal connections, I doubt you can get larger than 6mm into those and your meter tails are at least 16mm

That's just an isolator isn't it, not a changeover switch?

What about this Amazon special.

my bad, working on phone with small screen.

I've used this one before https://www.tlc-direct.co.uk/Products/CGM125CS.html

I suspect you will struggle to get meter tails in, it's rather small, and it's rated at 20Amps. More the sort of thing we use for commercial fans.

That's weird, I sent you a link to a 340v/32A one.

I'd be using it on the outgoing AC from my inverter to the consumer unit, 10mm² cable.

My idea is to wire the AC feed and the EPS feed into it, and then turn off the main switch on the consumer unit and run in EPS (off grid) mode while I've got full batteries, so hopefully Fed to Nov, and then flip the switches back during the crappy weather.

You still using a Nokia 5110 with Snake? Lol

sounds like you have a Nokia yourself

Ok 10mm from the EPS, but how are you feeding into the CU? Easiest way is changeover switch fitted into the meter tails, if I remember rightly that's kind of a legal requirement, the whole point of the changeover switch being to prevent 2 supplies into one board and isolate the grid supply to protect DNO workers digging up cables in the road.

Sorry Binky, I'm not following that at all.

I simply want to change from my standard AC supply out of my inverter, to the EPS supply which takes over once the grid goes down. So the changeover switch will have both outputs (AC&EPS) from the inverter going into it, but just one coming out of it and going to the CU.

Jeez, dont do that, not good, not safe. Youre relying on switching off the incoming feed and then switching over to the EPS then of course switching off the EPS and then restoring grid supply via the main switch. Theres potential for danger and equipment damage if you get this wrong, please dont do it.
Are your inverters OK with having their EPS outputs combined?

Nooooo, that's not the way to do it.

Connect AC inverter supply to the CU, on it's own circuit, connect EPS to change over switch , with the switch mounted in the meter tails. I'm not sure exactly what happens with the EPS feeding the CU, you might have to switch off the inverter cct.

I think I would have fed the inverter(s) from a separate CU, the house consumer unit fed from the meter tails via the change over switch, the alternative EPS supply being into the changeover switch too. By doing this, no danger of back feeding the grid or the grid feeding into the EPS output, normal operation is still catered for when the grid supply is on.

Can't back feed the grid with my suggestion or feed into the EPS, that's the whole point of putting the change over switch in the meter tails

But there was an issue with the feed to the inverter from the CU hence my suggestion

How are you connecting the additional CU?
