Is it now the case that all modern IT equipment and power supplies etc can be safely insulation tested at 500v? I have come across conflicting information and although I've done it I'd hate to think I may have caused a subsequent fault. I have a Seaward dvd which says not to do it, only the 100mA earth test, yet my Martindale manual, that's my tester, makes no mention of a problem and I've read elsewhere that equipment 10 years old or less is built to take it so go ahead. There are too many comments elsewhere saying 'it's not safe' for me to be convinced either way and I have a job coming up with a few pc's and psu's included so would appreciate any guidance.
