I've had this kind of thing pulled on me before, to. Start with their team leader, then group leader , then section head, then dept. manager, until you get satisfaction.
Peter Tarver [email protected] -----Original Message----- From: Doug [mailto:[email protected]] Sent: Thursday, October 19, 2000 5:43 PM I'm just about ready to escalate this issue. Issue: Major NRTL has recognized a DC-DC power supply. Said ps is being used within the confines of it's stated purpose, input power, output power, temps, etc ... Said product is submitted to NRTL for what appeared to be a walk through. Oh no, Mr. McKean. You can't use THAT power supply as intended. Input fuse of power supply (that is the fuse INSIDE the power that is out of our hands) is an AC fuse. It should be a DC fuse. (From the documentation from the ps mfr, the approval was done with the aC rated fuse.) You have to either: 1. have the ps mfr change the input fuse. or 2. drop an in-line fuse between the power inlet of the product and the input of the ps. EXCUSE ME!?! How the heck can a power supply mfr get NRTL approval on one hand and, yet, when that power supply is used within it's intended and stated purpose, get rejected? Even bringing this to the attention of the test engineer (who has approx over 10 years experience as a test eng) it defaults to - "well, that's just because the OTHER test engineer interpreted it that way ... " I can understand and have been in those areas of "interpretation" with NRTLs, but this one really ... er ... surprises me.
