I've got my IP44 fan to go in the hole in the wall. The wiring from the previous fan is ready to connect and............confusion.
The previous fan was a IP?? rated model with a timer built in. It had 3 core and earth cable feeding it via a triple (I think) pole isolating switch.
The new fan is an IP44 rated model without a timer. It appears from the instructions that this requires a different wiring configuration than a model with a timer.
The cable currently coming out of the wall at the "fan hole" comprises:-
An earth
A grey sleeved core with blue tape on it (assume N)
A brown sleeved core with no tape on it (assume permanent L)
A black sleeved core with brown tape on it (assume switched L)
This is switched by a triple (?) pole switch which sits outside the bathroom next to the light switch.
Examination of the wiring config in this large X-pole switch (the finger plate is nearly 2" wide!) shows 3-core and earth again with:-
A grey sleeved core with blue tape on it (assume N)
A brown sleeved core with no tape on it (assume permanent L)
A black sleeved core with brown tape on it (assume switched L)
These appear in the same locations on the "in" and "out" sides of the switch. Earth to switch back box.
Does this provide a reasonable picture of current wiring config?
The confusion is because:-
Wiring diagram in fan instructions only shows 2 wires going to the fan connection terminal - a live and neutral.
Vent Axia state that "the unit is double insulated (class II) and does not need an earth connection".
So which live do I connect to the fan? Black sleeve with brown tape or brown sleeve no tape? And what do I do with the earth where it comes out of the fan hole?
Hope this hasn't bored/confused anyone!!
