Big Spanners and Too Tight Nylon Glands?

Is this an example of over tightening?

Also some E.V. charger point testing at the end. Very interesting.

  • How did he know that supply was TN-S? Also it looked like the RCD was a Type A where is the DC protection in compliance with Regulation 722.53.2.10?

    I am surprised the plastic suffing glands did not jump a thread or strip the threads with that amount of force.

  • Interesting too John, he assumed it was TNS because the cable sheath was the Earth terminal. As we know this is meaningless, it may well have been TNC-S. I have not seen that cable he was using, looked like 3 core plus a twisted pair for EVs. Certainly not TT and whilst the RCD test was just OK, it was closer than normal, I wonder why?

  • Customers of mine are having an E.V. charging point installed by A.N. Other. The customers have to do their own survey and send photos of what they have got and emails with other information to the charger installers. I had to install a new circuit and have just left an outside 40 Amp rotary isolator. The charger is \Solo Smart Charger. A circuit with or without R.C.D. protection is acceptable according to the installer's letter. NO TT requirement is made. The installers know that the supply is P.M.E. They are happy with that.

  • P.S. BUT if an R.C.D. is installed it must be a Type A the installers say.
