Hi Dave sorry to answer your questions
How many properties? 1
Single or 3 phase supply requested? Single
What rating (how many KVA) have you asked for or been offered? 20 KVA
How far from the 3 phase overhead to your plot? I would say about 100 meters
Is that going to be overhead or underground? if so who is doing the digging? Underground and I will do the civils
Is the 11KV overhead being altered in any way or just a transformer and your connection? It may well require an upgraded pole or twin poles for the transformer) 11Kv work will require a partial network shutdown, that is not done live. they have not stated
thanks
