    Default forum response to DIY enquiries vs. skills shortage

    To the qualified electricians on the forum: The default response to DIY enquiries on how to do stuff seems to be "Get an qualified electrician in, it's too difficult for a DIY'er to do". Given the skills shortage within the industry, is this a reasonable response? Is there another way?

    Dead honest true. Couple of years ago I asked two unrelated friends what was the key to their successful, 6 figure salary, careers in highly competitive fields. Answers (verbatim) were, "Know which arse to pucker (kiss) up to?" And the other was "Know where the blame is going for any project...

I was taught to move the switch and...

    Regulation 434.5.2 Fault current!

    Cant quite get my head around how you use this reg? Lets say S =16 I = 657 k = 115 You have to work out t first of all so t = K2S2/I2 so t = 7.843409 (to 6dp) therfore K2S2 = 3385600 The reg says that we need to make sure that K2S2 is greater than the value of the let through energy...

    Will a reading higher than given in 7671 for Zs values be okay if protected by RCD

    I might be COMPLETELY wrong.... but I have recently finished my level 3 in college and I'm sure I was told that if a Zs value is higher than the max reading in BS7671 it's okay if it's protected by a 30mA RCD, so it passes. I sort of remember writing 'satisfactory' on the test form next to Zs...

What is the rest...
