Putting a DB in a hotel extension

[DaveW4]

I am currently attempting an assignment which involves installing an EV charging unit in the car park of a hotel extension, the extension will have its own DB. Although not part of the assignment, I was interested in whether the new DB has its own feed or will come from the main DB in the hotel. I would also like to know that if possible, how will the new DB connect to the main and the effects it will have on it? First time user so please forgive any inaccuracies or lack of correct terminology.

Job to know without more specific details but would think DB circuit off main DB and EV point off Sub DB would be easiest.

This sounds a lot like you are trying to get us to answer a homework question.

As I stated, my question has no bearing on my assignment, I was and still am interested. In fact, I have already completed that part of the assignment.

The electrical charging unit will be supplied from the TNCS supply in the main hotel buidling.

Dont forget to draw in the earth fault loop path too, many in our class forgot that first time round.
