Frequently asked questions
Do I need a 3-pole fan isolator?
For timer, overrun or PIR fans, yes. A 3-pole isolator breaks the permanent live as well as the switched live and neutral, so the fan is fully dead for cleaning or repair.
Where should a fan isolator go?
Accessible but outside the bathroom zones, commonly just outside the door or in the loft space near the fan.
What rating fan isolator do I need?
A 10A 3-pole fan isolator suits standard domestic extractor fans.
