I didn't fit an isolator for the two units so to turn off all power to the building you have to turn off both RCDs. I know there was...

    TP Fan Isolator in Shower Room

    Went to look at a job yesterday, shower room refurbishment. I'm just replacing the existing main light, vanity mirror and dual fuel towel rad.

    Isolator for more than just a fan

    Was thinking the other day about how you need to have an isolator for a extractor fan. Would anyone agree that you would also require one for say a mirror light/shaver light??

    I need to replace the feed for an extract fan from the bathroom light and need to know if I'm required to install a fan Isolator switch, as currently there isn't one or if I can just replace the cable? It is a timer fan and looks to have been wired using 1.5mm flex, with the earth being used...

    Blue C Form plug on cooker

    This may sound odd, but is there any reason I can't pop a Blue C Form plug on a cooker - new range cooker arrived and it needs only 20 Amps as most of it is gas except for one oven and the igniter.

    FCU for Extractor fan

    Adding an extractor fan off of a 6A lighting circuit. Installation instructions specify a local isolator (as I would anyway) so 3 pole isolator will be used.
