Can someone tell me what cable size should be required to run a power shower and does it need a pull switch same as a electric 1

A power shower can be run off a 3amp fuse connection, so 1mm cable will do, an RCD unit will need fitting too, this comes under Part P of the building regs as notifiable work, if new circuit and or protective devices are being installed.
You can buy fused connection units with RCD protection incorperated.
a Power Shower is different to an electrical shower.
