Socket outlets for commercial will require RCD protection unless as risk assessment is carried out.

You could have one DB supplying all four doors with one RCD main switch to cover all circuits or all of them could have individual protection. This is for you to assess and design accordingly in discussion with your customer.

What is the intended use of the building?

Could the doors be hard wired into isolator switches?

Are you intending to carry out these works in the UK.

Your profile suggests you aren't in the UK so it's a bit pointless us advising you on UK regulations
