I agree, the option to connect/disconnect the earth to the sockets would be nice. I'm hoping that we can work on a modification to make this happen. I will post some detailed interior photo's during next week.

It will be really interesting to see what's inside, I found a teardown of a smaller unit on YouTube, that one has a soft-start circuit, I'm assuming yours has it too.

I'd definitely check yours over inside before using it as after watching that video it does appear it is just a typical far east design and re-badged for Bronson++ I wouldn't say any of that is their design internally looking at the construction, wire colours and also the PCB definitely looks a far eastern design. Very similar construction to the far east "Variacs"

Hopefully it works well and is safe/can be made safe. Do you have anything there to test the insulation resistance on the transformer, such a "Megger type tester" or a PAT tester, as it's a toroidal transformer. I wonder what voltage/va rating is on the transformer. I really want to know why they thought a fan was needed.

No luck at all hunting down one of the Screwfix 3000VA's so getting sorely tempted by one of these, I really hoping yours checks out well  :-+

djsb:
Can't PAT test it at home.It has a soft start function as well as short circuit and over temperature protection. It's a 3KW 12A version (2400 Watts continuous). The case has a Fan aperture on the rear. I will see if there is an actual fan when I open it up. More later in the week.
TheBay:
2400w continuous is quite impressive! I look forward to seeing it.
I've got a version of it saved on Amazon ready to purchase, but for some reason the 1:1 version is more expensive than the 110/230V in. :-//
Is this the ASIN of the one you ordered: B07JMCFNLM ?
djsb:
The ASIN of the one I bought is: B07JMCT1BZ

Bronson++ MII 3000 Isolation Transformer Toroidal Core 3000 Watt - In: 110V / 230V - Out: 230

Also, maybe a slide switch like this could be inserted into the front or rear panel to connect/disconnect the earth to the sockets
