Hot tub earthing

[Welsh_sparky_21]

Been asked to run a supply for a hot tub, looking at the spec on it online. Comes on a plug top but it also says you need to run a separate earth out to it, anyone else ever had this? Surely the earth will come from the plug top. Seems a bit overkill

There's several other threads on this exact thing. Worth having a search.

Says 2.5mm minimum, strange a thought
