(OP)
The majority (old & new) of our production motors (pumps, agitators etc) which are on automatic instrument control will run when the stayput e-stop is released, as the instrument contact is either closed (asking to run) or open (asking to stop). Some newer systems use a pulsed start (with parallel latching contact) & a separate stop contact.
The question is this:- The former design has been in use for some 30+ years, I don't think it complies with BS7671:2001 (but I struggle interpreting the relevant regs). Assuming it doesn't comply now, would it have complied 30 years ago?
Thanks in advance,
Alan

I can't speak for the USA, but in the UK,legislation & regulations change over the years. 30 years ago I was playing with action men & toy cars, I had no interest in electrical safety!!
