W'eve had a couple of incidents where nurses have received minor electric shocks from medical equipment that was not plugged in!!
They got the jolts from touching the live and neutral prongs of the mains plug after removing the plugs from the mains outlet. Our Sherlock Holmes discovered that the culprit was the mains interference IEC connector in the equipment. Some IEC filters have capacitors across L&N whilst others have bleeder resistors of about 1Meg across the caps as well. [see RS catalogue Sept2000 book1 page 361/3 for different types & specs]
Are there any regs governing this?
Has anyone else come across this phenomina?
