How much power does an outbuilding need?
What you plan to do in the outbuilding will dictate the power required. If all that is needed is a socket or two and some lighting, then the power requirements are fairly modest, a 13A supply would probably be more than adequate.
Can a cable be used outside?
For more details including current ratings for the different cable types please see the main Cables article. Twin and Earth cable can sometimes be suitable for use outside, although generally it is better protected inside conduit or trunking. Note however that it is not robust enough for direct burial.
Should power feeds be protected from a dedicated circuit?
When protecting power feeds to freezers or boilers in outbuildings, it may be appropriate to feed them from a dedicated circuit and treat them as fixed equipment. Thus the can be placed on the non RCD (or higher trip threshold) side of the outbuilding CU.
Can T&E be used outside?
T&E would usually only be used outside for short runs, often clipped to the outside of the main building and out of reach in a location unlikely to be subject to mechanical forces or movement. Typical applications being connections to outside lights.
Can a TT earthed outbuilding be exported?
When exporting an earth, the earth continuity must be maintained all the way through the installation from head end to submain, and into the final outbuilding circuits. With a locally (TT) earthed outbuilding this is not the case.
Should I take power from a non RCD protected way?
If you have a TN-S or TN-C-S system then you would ideally want to take power from a non RCD protected way on your consumer unit, this is to guard against the outside power feed increasing the likelihood of nuisance trips being caused on the household RCD, and also to prevent the RCD from making discrimination difficult for the outbuilding supply.
