Does anyone know where to get a relay to switch current between two appliances, so only one works at a time.
Its for domestic application. Electric boiler with electric shower in the house as well. Obviously thats too many amps, so looking for this device (off the shelf).
Thanks

Why obviously? How many Kw is the shower, the boiler and what is the maximum current rating of your supply?
 
You just need a NC (normally closed) contactor of suitable Amperage for the boiler wired to open (switch off) when the shower is operated.
