Dear colleagues- I'm trying to get up to speed quickly with 61010-1, & need some help interpreting the leakage current limits of IEC 61010-1 and when to apply them.
What is the maximum allowable leakage current per UL-61010-1 for U.S. and Canada? (the available Digital View UL-61010-1 shows only the North American National Differences with no mention of leakage current.) Referring to IEC 61010-1 Clauses 6.3.1 & 6.3.2, how should one differentiate when leakage current is sine (mostly) and when "mixed frequency"? What if there is also a significant d.c. component present? (O'scope jacked in to Simpson leakage tester a la Pete Perkins, okay, I understand the importance!) This seems wide open to interpretation, with risk of third party inspector seeing things "differently." The product is an outdoor optical imaging system for remote inspection of manholes and other infrastructure below street level (wet environment). Mains power (120V/60Hz) is taken from either onboard, truck mounted generator or shore power connected to the truck. A pair of 60950 approved PSU reside on the front end, with secondary side outputs of 48VDC and lower voltages.
