Pure sine wave inverters. 12v /230v

It's the most ludicrous proposal I had seen in a long time which I suspected to be trolling and not a real thing. After a while it started to nag me that he might actually be doing this for real, so I replied. I wonder how many people have had shocks since the thread was current 2 years ago.

Hi @HowelGrace, welcome to the forum. I get that your post is ironic, but I'm not sure what the OP would make of it? I worry that it might be taken as a compliment! Being over here in the UK I'm a bit rusty on the NEC, can you remind me which code chapters deal with back-feeding of panels and interlocks?

Quite frankly its a bizarre solution for a problem that i solved over 30 years ago. I had Motorhome, needed 240V for phone chargers, nice TV, sat receiver and playstation, so wired an inverter, as you do, BUT it was terminated to a dedicated double socket where all the above were located and next to a double socket which would be powered under hook up conditions. All i needed to do was unplug the stuff from inverter socket to hook up socket. Terminating on a plug and then backfeeding the whole electrical installation was simply not necessary so i do not understand what problem is trying to be solved here.

If the OP was serious, neither do I. Or rather, it's a common problem with a very simple solution - a 3-position DP transfer switch. The OP claimed there was no room for the switch and I appreciate that not every motorhome has a conveniently located engine room like my boat (where my ATS is). OTOH I presume there was still some space at the morgue.
