Two wired extractor fan connecting to three wired old fan

[Will Angell-James]

Hi!

I am removing the old extractor fan in my bathroom - the old has three wires - live, switched live, and permanent live. It is hooked up to the fan isolator.

my new fan only has two wire inputs. Permanent live and neutral.

can I use my new fan with two of the three wires which went into the old fan? And then wrap up on unused wire in electrical tape?

I purchased the two wire fan by accident.

thank you!

You mean - Neutral, Switched Live and Permanent Live.

No, it has Switched Live and Neutral.

can I use my new fan with two of the three wires which went into the old fan? And then wrap up on unused wire in electrical tape?

Yes, wrap the Permanent Live - but it would be better put in a separate connector block.

You can nick a connector block from the old fan to put the spare permanent live wire in.

Your room, from its construction, may require a fan with an over run timer. Does it have any form if ventilation, an opening window perhaps?

Better to return the wrong fan and use a timer fan.
