I originally put this up here to try and show people that putting too many appliances through the circuitry may have dire consequences.  I was naive, but lucky nothing has happened.

On any extension from a standard socket (which is what this is), add together all the fuse ratings of the applicances you want to connect to it. If it comes to more than 13*, don't do it. Yes, it will probably work if it's a bit over 13 unless all the applicances are drawing close to their fuse rating, but it simply isn't worth the risk.

*assuming that any 4-way adapter used is also rated at 13amps

As I understand it, any wiring to a shed should come direct from the main Consumer Unit, or 'Fuse Box' on a dedicated circuit. That is also where any RCD should be located.
No you  can  run a  fused spur off the ring final,only drawback there is your limited to 13A max load

a heavy duty plug is fitted with a five amp fuse (Why did yours not blow? - even a 1500 watt heater draws more than 5 amps). The armoured sleeve round the cable is bonded to earth through the RCD socket.
Steal wire armour is not and never was intended to be terminated into a plug. And now we open up a bigger and potential more dangerous problem,the earthing arrangement,put simple its best not to take your earth from the household supply,instead use an earth spike at the shed end.

I thought lighting circuit switches were typically rated for 10A,
plate switches rated for 20A are common enough and look just like a normal light switch,its only when you turn em round and see there double pole that the games given away

Or you do what I did today, and stop asking so much from your power supply.

I've learned my lesson.

On a final note from me this link should be a good starting place for all those who are Installing/using electricity in an outbuilding.

Thanks for the clarification. :thumbsup: My comment was based upon my electricians conclusion for what I had initially planned for my shed, where the total amp usage could have exceeded 13amps.
