catenary wire minimum height

[flukey]

i have a shed supply to install on a catenary, and looking in brb it would appear that it needs installing at a minimum of 3 metres above ground
it is coming from the corner of a bugalow to the shed and there will be no vehicles coming anywhere near.
what heights do you lot normally install at in these conditions as i would have thought 2.4 would be more than enough

As the BRB says minimum 3m, then that is what I would install it at!
