Hi guys,
a baffling question (well in my mind anyway). I got called to have a look at some wiring for an old Victorian built property, its a friends property and as I only stick to domestic installations he wanted me to have a look at this commercial use building. Basically it's got 5 floors starting with the lower ground floor which is where the meters are. As all the floors are seperately rented out, he has the top floor spare and wants to convert this in to a residential apartment.
Bare in mind this building is very tall and is pretty huge with high ceilings.
Now ow I know in a domestic installation if the consumer unit is over 3 meters away an 80amp isolator would be needed and then you could carry on as long as it was within a reasonable amount of distance, taking into account voltage drop and other factors.
This property has the meter in the lower ground level which is the cellar and the consumer unit would obviously go in the top level. This I worked out would be over 30m in length.
my question is, what is the way around this? It is a three phase supply and he said he would be getting a complete separate meter just for this apartment. But doesn't wants to install this in the cellar.
How would one get around the issue of voltage drop and stuff??? As this would be too far for the cable presuming 25mm tails.
thanks in advance guys
