RE: Earthing at PWB for UL508 Power Supply

Dear Gary, I am not talking about an earthing trace on a PWB relied upon for BONDING purposes. The power supply in question has an earthing terminal (terminal block) directly mounted to an earthing trace on the PWB. Such a terminal is not used for bonding purposes (in which case what you say i

water-cooled electrodes

I would like to know if anyone in the group has been involved with the AGENCY APPROVAL of a product containing a water-cooled live electrode or coil, and what had to be done to make this safe in the eyes of the agency. My company is occasionally involved with this sort of thing, and some feel that

RE: FLAMMABILITY ratings. In UL 1950 3; EN 60950, what do we need to consider with reference to grommets protecting insulated wire through a metal bulkhead within CLASS I EQUIPMENT? FLAMMABILITY, dielectric, abrasion etc. Does small size exempt it from a burn rating? (mounted in a metal pan

RE: Cable Shielding

You might try capacitively coupling the cable shield at one end. We had some success doing this at a company I worked at some years ago. We mounted the connector shell to a copper plane at the component side of a thin PCB. the bottom plane of the PCB was in contact with the chassis of the unit. The

Re: Serial Numbers

Hi Scott: There is no requirement that "ratings label" data be provided on a single label or in a specific location. You have already mentioned that specific data must be located near the device, i.e., input ratings near the power input, fuse ratings and fuse replacement warning near the fu

RE: Three Phase Wiring

I believe these colors to be correct. It is puzzling however that we have one brown and two blacks representing all three phases. Some three phase devices are phase sensitive (motors for example). Why not three different colors, e.g. Brown, Black and ? Rick Busche rbus...@es.com
