New build with recycled parts on a ridiculous budget 120cm*60cm work area

A dedicated supply is obviously the gold-plated solution but I'll think you'll find that pretty much everyone with a similar machine runs the machine off a single 13A socket. I use a 4-way adaptor for control box, inverter, and PC all going back to a single wall socket. No problem at all. Don't be misled by the inverter rating. That's max output power and it's unlikely that you will be pushing it that hard, if ever. Run the vacuum cleaner off a second 13A socket but loading is fine even if it is the same ring. In other words, you could swap a single 13A for a double and still be ok. Even if not a ring and single socket is on a spur, I believe that that should be good for 20A/5KW total load (but would need double socket).

No allowance for kettle in that, of course! Sure it's only 1KW?

Thanks for the advice, this is not in a home so unsure how many sockets are on the ring but if I ever move this to my house this will be a consideration.

I have a caravan kettle, It's single phase but only 750w I just rounded up. It's very annoying lol as it takes ages to boil but it was of course free ;)
