robbo 802 Posted January 5, 2015 Report Share Posted January 5, 2015 as an electrician of 35 years i can honestly say that as long as the correct breaker is used to supply the cable [i.e. 20 amp for 2.5mm] and it is protected by an rcd there is nothing wrong with using flat twin and earth to supply a shed or garage. it has to be installed properly using a catenary wire or conduit etc. to support it and the length of the run has to be taken into account to keep volage drop to an acceptable level. it should also have an rcd mains [garage kit] installed at the shed as this is a detached building. as for just using an extension , this is fine you just need to make sure it is plugged into an rcd protected socket. it isnt the best method but isnt a danger to life so long as its protected. Thousands of older houses still have old rewireable fuse boxes so check yours has an rcd if not buy one of the plug in types[powerbreaker] 1 Quote Link to post Share on other sites

Rabbithunter 456 Posted January 5, 2015 Report Share Posted January 5, 2015 make an extension lead with whatever size you want,..... aslong as the "fuse" is the "weakest link" in the circuit its no good putting a 13amp fuse in the plugtop if the cable isn't rated for 13amp, as the cable would burn out before the fuse! 1 Quote Link to post Share on other sites
