Garage supply

Former Community Member
Former Community Member

Hi all,

 

I’ve recently been asked for advice and found myself reluctant to give an answer without a second opinion.

Question - 

Is it possible to run in a garage supply using 4mm SWA off the house ring and protect the garage via a CU - 25A RCD with 16A and 6A MCB for sockets and lighting? 

The garage is located at the very back of the house, the DB is at the very front and there is one ring circuit for the upstairs and downstairs (Kitchen is on its own ring).

My personal opinion would be to run in a new supply from the board in the house, however accessibility is supposedly an issue and the house has been recently renovated. For which reason this method of supply has been suggested. 
 

Many thanks in advance,

 

Jack

    My take is that a ring final cct is a final cct in its own right. However if a further fuseway (fuse or breaker for example ) is attached then the downstream circuit is also a cct in its own right and the ring final supplying it is its distribution cct.

    So, a ring final circuit is a final circuit and if supplies another (fixed) circuit is is also a distribution circuit.

    Some tings are one category some are another and some are both. 

    Of course a plugtop plugged into a socket on that ring running say a kettle, lets it run the kettle and is its own circuit but it is not part of the fixed installation.
