Hi
Alas, there isn't the required information on the A1024 label to be able to investigate what it is for. Sometimes the info will be written on the back of the ticket, to protect it from the elements causing the info to fade.
Basically the A1024 process is to highlight plant issues such as defects (missing pole-steps etc) to low wires across a carriageway. There are many, many things an A1024 can be input for.
What I can say though, is that Ramsgate DP531 isn't listed as being a D-Pole though and therefore not down to be changed. It was last tested in October 2016 and passed. All I've got, I'm afraid.
