Confessions of an Electrician...

Lisa Miles

So while we’ve not been able to log into the community (you can do so now if you didn’t already know) I’ve been keeping myself out of mischief Blush by going through some of the discussion topics on the old Wiring Regs forum and came across this one: Walking off site where some of you were sharing stories about your experiences with client's pets while on the job. 


So I thought it would be a bit of fun to ask you to share some of your funny/bizarre or just weird stories (keeping it relatively clean and protecting the privacy of others please!) from any jobs you’ve been on or done.


… And I’ll send some swag to the author of the story that gets voted the ‘Most helpful/liked’ from the community so don't forget to hit that 'Good Answer' link on any that make you chuckle! (Log in required)

    Thanks, Alasdair.......could you quote the text of 554.2.1 please?


    Denis,

    All it says is:
    554.2.1 Every heater for liquid or other substance shall incorporate or be provided with an automatic device to prevent a dangerous rise in temperature.

    As you can see there is nothing about electrical protection or isolation.

    Thanks Alasdair. I have played through the "suicide shower" video again. It seems that the shower contacts are pressure operated through the diaphragm. I am concerned that if there were air bubbles in the water supply a situation could arise whereby the shower was under pressure but the heating elements were surrounded by air, which would not readily escape downwards, hence overheating.


    The instructions specify resistivity of the water. I am not impressed. It would take more than a simple test meter to check this. It would need laboratory equipment whereby current was passed through a tube of water of specified length and uniform cross-section area. And is the water in South America quality assured for resistivity? I don't think it is in the UK; I've never seen any reference to resistivity on my water account.


    The use of a bare earthed wire to keep the water output at earth potential seems woefully inadequate. I could have hoped, at least for something like an earthed coarse wire net filter through which the water passed.
