Due to frequent power cuts I intend to use an existing 2.5kw generator to give back up supply to fridge and freezers in garage.
I can isolate the mains supply from CU to garage and re-route via a 2 pole changeover switch however, what about the earth.
Can I safely rely on the existing mains earthing or do I need to instal a new earth from the genny and if so, does the genny need an earthing rod? Advice please!
