I have been asked to ‘bond’ some tables or industrial sized wash bins by the engineering supervisor here at work. People stand and work out of these. Simple structure with water that’s filled from a hose. Q “can you bond these tables, and what do you think?” Me. “Well, seeing they are not part of the electrical installation, and are very unlikely to be extraneous then No” I then explained about the 23K rule and how it comes about. We had a professional chat about it all but couldn’t convince the other party completely and they still think it’s required . Now he’s probably forgotten more then I’ll ever know regarding the machinery here but I have spent long enough in electrical installation and design to be confident. He also cut his teeth back in the 15th which was obvious when I was told you have to bond sinks, ‘cross bonding’ etc. Anyway I degress.....so I marched off my my AIO tester in hand. Tested the table to a known earth. With the floor wet and the table sat in the water, metal wall panels and with no surprise at 500V test voltage 0.1Mohms. I’m aware that going around bonding anything metal including the tea bag caddy can increase the risk of shock and I’m trying to prevent this culture from starting. So let’s discuss either my misunderstanding of electrical theory or how I can science my way out of this hole. Discuss.
