Q & A of the Day - Is our electrical circuit design OK?

Question: I have query about whether our design will work or not. We have two lighting circuits, nos.1 and 2, so this means use of two MCBs, as you will see in the attached PDF drawing.

We are taking circuit no.2 from the distribution board (DB) to the lighting pull box (LB), and from panel to that box we are pulling three 1.5mm cables for phase, neutral and earth. From that pull box, we are separating circuits with Wago push-wire connectors as nos. 2.1, 2.2, 2.3, etc...circuits to control with different switches.

Is there any problem with this method according to relevent British Standards, since we had a doubt about the MCB and cable size?

Answer: In principle, we can't see anything wrong with your design.
