Can anyone tell me what MCB I should be using for this set-up.
The objective is to bring power to a shed.
Starting at the house end, I have a spare MCB slot on the RCD side of my split load CU.
I have an 8 meter run of 2.5 T&E to a switched FCU. From the FCU the 2.5 SWA exits the house and is buried under a pathway for 15 Meters. On entry to the shed the cable runs to to 2 Double sockets in series. Before the first double socket a 2.5 spur runs to a 5 Amp switched FCU. From the 5 Amp switched FCU a 1.5 cable runs to a light.
It is not a big shed so only standard hand held power tools would be used there (no industrial lathes or anything).
Question is, what sized MCB should be at the CU and what sized fuses should be in the FCUs (I know it should be 5 Amp for the light spur).
Thanks
