Is their not a forum trainee or DIY section?
There is, and hopefully the OP will now post there in the future

The regs are there to help you out in this situation. Have a look at the current carrying capacities of SWA, installation method comes into play and also volt drop. I'd say that if its 20feet max then your not going to notice much volt drop but just to 'cross the Ts and dot the i's'.
The current carrying capacity tables are no use until a figure of In which has been adjusted according to correction factors has Ben established
If he only 'probably knows' he shouldn't be doing the job.Sorry for late reply. Battery died
I should have explained. i was given this information from a friend of mine who is doing the job, I'm just helping and watching really. I was just thinking out loud and wanted to know what size swa would be needed. He probably knows already but I wanted to see if I could figure it out myself.
i guess I would need more information to really work it out
You are spot on. I was only joking. In the real world a 6mm swa will suffice for a long long long time .Come on the OP is a trainee, the posts above are hardly productive ?
wow .you are spot on. I was only joking. In the real world a 6mm swa will suffice for a long long long time .
Truth be told a 2.5 wouldn't come to any harm either. There is never likely to be any substained load on this cable
I thought op had already worked out In as they stated the value of 40amps
It's a shed with '5 sockets in and some basic lighting', op didn't state they were going to be running a machine shop out of it. I understand where your coming from. Obviously if he would have said what he was intending on using the shed for and then listed in detail every piece of equipment that his friend would be using then I would have been happy to point him in the right direction as to what size cable he should be installing. But instead I pointed out that maybe using the In value that he imo had possibly sat and worked out (seeing as it's only 5 sockets I'd have said he had no intention of pulling 40amps) he could look at the tables in the regs and then come to a conclusion for himself and then possibly come back and show how he come to his decision and then we could help out from there.The chances of the application of all factors resulting in a value of 40A is pretty unlikely don't you think?
