Hi,
Got an undersized cable going to a garage not sure how to code it:
Cable is 2 core 2.5 SWA at least 40m long
Cable comes of a 15a 3036 fuse in the house and splits into DB3 (a 20a switch fuse coming of the live side of DB4 main switch) and DB4 an old wylex rcb main switch board with 2 16a and 1 6a plug in RCD.
Obviously voltage drop way above 5% but essentially the whole lot is protected by a 15a fuse in the house so more a nuisance than dangerous.
The earth is exported via the steel sheaf from the TN-S in the house. I know it's generally advised that anything over a 20m run should be spiked but I need a reg to back that up.
Any thoughts?
Steve
