Priority Switching Boards, more commonly known as ‘Shower Boards’ are designed to normally facilitate the use of two electric showers which are being supplied from a domestic 63A single phase supply like you have in your home.
We install the same unit if you have a 32Amp Car Charger installed because both units may continually use >3kW of power each.
We set it up so that your Electric Shower has priority over your Electric Car Charger. Your Car will charge when plugged in, but if your Electric Shower is turned on, the Board will automatically cut the power to the Electric Car Charger thus protecting the main supply fuse. When the Shower is switched off, charging will resume as normal on your Electric Car.
