How are hand wires in toilets wired up?

johnwicklover

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.
