Booklet says 230v power supply (50Hz)
I have recently got a new cooker which i thought i'd be able to slot straight in in place of the old one, however, the old one ran off of a plug and my new one is not supplied with a plug although it comes with wires.....is it OK to stick a plug on it or do i need a cooker switch box thingy?
