How are hand wires in toilets wired up?

So how are hand dryers usually wired in a radial circuit?

Is the supply cable from consumer board connected to supply side of a FCU and then the load side connected to wago connectors (L and N have their own connectors). Then hand dryer connected to the wago connectors. Then a second FCU is connected to the wago connector and the load side of second FCU  connected to the Hand dryer.

Thanks.

  • I think you are complicating matters. One FCU, outgoing cable then supplies the hand dryer. If there is a hard wired cable on the hand dryer, then connect to that inside the hand dryer to make future maintenance simple.

  • If the radial only supplys one dryer, then you can set the breaker low enough that you do not need the FCU, though some sort of switch is a very good idea, often  high up near ceiling in buildings like pubs where interference is likely.

    If you have a 20 or 32 A circut supplying a no of dryers then each one would normally have its own FCU,

    Wire between dryer and first fixed item is flex. Joint may be Wago  or chock blocks.

    No need for 2 Fuses.. At most the 2nd box near the unit  is used as a junction between flex and fixed wiring.
