Many thanks. I didn't mean to imply I wanted to open up the switch. So I can turn off the switch and then it's safe to prise the fuse-holder open. I don't need to turn off the mains power supply.
Many thanks.
Sorry about this, but this is so simple it defeats google.
I need to change the fuse in a fused switch spur. Is switching off the switch on the fused switch spur sufficient, or do I need to turn off the mains power supply?
Sorry again for such a simple question. :oops:
