Need to convert a 277V outlet to 110V? Long story, but I have a 277V outlet and I obligation it...

Long story, but I have a 277V outlet and I obligation it to be 110V to plug in regular electrical appliances. How do I shift about doing this? I do not want to have a massively high nouns on the socket, just roughly 5A or so. I need to do this economically and as you can put in the picture by my question, I am no pious at electrical work. I can plug stuff in but that's around it. Any links to suitable transformers would be appreciated
Thanks.
