A video games enthusiast has a number of Japanese computers and games consoles that require a 110V AC mains supply. At the moment they are powered using either individual 230V to 110V stepdown transformers or from shaver sockets but they are power limited to 20VA. It would be more convenient to install 110V wall sockets powered from a fixed stepdown transformer. I have seen 230V to 110V stepdown transformers that are DIN rail mounting so they can be installed in a consumer unit.
Are there any wiring regs concerning a fixed 110V mains supply? Something that I am aware of is that if a stepdown transformer is located in or near to a consumer unit then an RCBO or RCD on the primary side will not trip if there is an current inbalance (electric shock?) on the secondary side. Is there a (legitimate) way of connecting an RCBO to the secondary side?
