Which arrester mounting is correct? A picture showss the arresters mounted in two different ways.<br /><br />

In both cases polymer type arresters were used. These type arresters are not line/load sensitive and can be connected either way. These arresters were mounted in the vertical plane and it is best to keep the skirts of the arresters pointing in the downward direction. Since the line and load connections were different in the two sections, the connections had to be reversed to keep the skirts pointing downward.

Both sets of surge arresters are correctly installed.
