Having bought a small generator I'm now reading the manual supplied
with it - the manual is not very good.

In the manual is a diagram showing the earthing point (frame) of the
generator being connected to a ground spike, but there's no helpful
words to advise that this should be done.

Am I supposed to connect the frame of the generator to an earthing
spike driven into the ground when in use? What size spike?

This is only a tiddly little generator - 240v/950W rating.
