Building a small one bedroom house (7mx7m).  Wife wants to add a covered patio later with a couple of lights and outlets.  Should I split the C.U. inside the house and add a small weather proof C.U. wired for later use?  Or is there a simpler way ?  As always, thanks for your advice.  P.S. Not our main house.  House is for visiting family.

It probably depends on the number of free slots available in your current C.U. You can use that or add another one.

 

We have just just had some outside lighting and power added and I decided that it should have its own RCBO and MCB's together with its own time switch so adding another C.U. made it simple to understand what is where. It isn't weather proof as it is inside the house.

Should be OK just run wire to a junction box (covered) to the patio that is up and out of the weather.  If you have separate light and power circuits, use two boxes.  

Thanks for your response.  I will run two lines from my C.U. one 15 A for lights and  one 20 A for outlets.  Bundle them in a weather proof box for later use.

A CU wired by a Thai Sparky.  Unfortunately the footprints belong to the owner of the house after the first "blacout".

15A for lights! Do you mean the circuit breaker or the capacity of the cable. 

 

6A CB for lighting is normally well sufficient. 

 

10A is 2200 Watts. @ a supply V of 220v
