    Fan isolator switch access

    I have attached a photo of an isolator switch which is for an extraction fan in my kitchen. The only way I have found to switch it off is to take the front plate off which then gives acces to the switch.

    Need help with wiring a fan isolater, testing unit possibly broken.

    Hi, I had a problem with the fan isolator in the bathroom and it cut out. So I had a look at the switch and replaced it. But that didn't fix the issue and I am wondering if the unit itself has gone. Is there a way that I could test it? This is how the switch was wired. And this is...

    Bad experience having isolator switch fitted by Scottish Power/Actavo

    I "recently" contacted my DNO to have an isolator switch fitted beside my meter (my consumer unit needs changing and I didn't want to pull the fuse).

    Fan Isolator switch alternative

    Hi. Random question, but in our utility room we have an extraction fan like what is normally found in a bathroom. Currently doesn't come on with the light or anything like the bathroom one.

I've only seen the main switching device as a mccb or acb. I know that in a house you'll have a...
