Why do you need 3 RCDs? Wouldn't just one in the house be sufficient? And perhaps the circuit attached to a light in the house to signify power to the shed was OK.

Vision On and various programmes hosted by Tony Hart after Vision On finished.
Well the iron and weight could be quite heavy with the iron just a tad lighter. When the RE magnet falls and releases the iron, the weight will= pull it up to the pulley where it will get stopped. The weight continues= to fall raising the flag with all of it's weight acting on the string. The weight can start near the ceiling.

The magnet activates a flap which releases a ferret.
The ferret then chews through a marmite-smeared [1] string, which breaks thus releasing a weight. The falling weight powers a generator which powers a laser aimed at the house windows. Using a small motor and mirror assembly it then writes "freezer fail" in charred letters on the wallpaper.
If a duct is available between shed and house, appearance in the house of the ferret may mean that the laser becomes superfluous.

Shed has the CU which used to be in the house - so 13 amp and lighting circuits (and possibly others) can be run round the shed. Shed is 'Mother Of All Sheds' posted about a couple of years back, so quite large.
So there is an 13 amp circuit with a breaker, whole CU breaker, then an RCBO in the new fuse board in the house.

yebbut still the only thing keeping your weight up aloft is the RE magnet holding some lump of iron? ergo large RE magnet and =A3=A3=A3, also take longer to warm up and drop once freezer fails... all for a load of 2008 lidl fishfingers?

No. Say the weight weighs 1kg and the lump of iron 999g all the RE magne= t has to provide is 1g of attractive force for the system to be balanced and thus static. When the magnet falls away under it's own weight (it will have to weigh more than 1g) the iron/weight/pulley system is unbalanced and the weight can lift the iron to the pulley.
