Posted By Michael Turner Hi We operate in an industrial environment, and have a small team of time served electricians (16th Edition qualified) who maintain all the on-site plant and equipment. I have just been picked up on an audit for not having put our electricians through the 17th Edition update course. While this is an objective for 2009/10, I am a little unsure as to the exact requirement for them to complete this training. Thanks for the help.
