Do not know why bonding materials/construction would not be in the scoped safety standard. My typical refs for reliable bonding construction requirements/suggestions are: 1. scoped safety standard for the equipment and/or end-use installation. 2. CSA design manual for the scoped standard(s). 3. Section General and/or Inspection Procedures of the affected UL file. 4. CSA No. 0.4 5. NEC article 250 (mostly wiring, but other hardware discussed)
There has to be 10E3 references for this stuff. Brian -----Original Message----- From: emc-p...@ieee.org [mailto:emc-p...@ieee.org]On Behalf Of Brian Ceresney Sent: Monday, December 17, 2012 3:59 PM To: 'EMC-PSTC' Subject: Standard or practical guide to grounding electrical products which are not permanently installed Dear Regulatory Experts, I'm searching for a standard or guideline which will provide detailed information about the internal grounding and bonding of products, and I've had limited luck in finding anything suiting my purpose. Reviewing a few CSA and UL standards hasn't been helpful. Specifically, I am interested in Class I plug and cord connected products, which require the internal grounding wire to be secured to a metal, non-current carrying enclosure. I need to know what kinds of screw/nut/washer combinations are acceptable, mainly from a North American viewpoint, but not excluding Europe.(As usual, I'm working with small industrial-type battery chargers drawing less than 12A at 120V, 6A at 240V). I'm particularly interested in requirements/acceptability of thread-cutting or -forming screws, with or without locking washers. I'm wondering about their securement performance over time. The standards I've reviewed so far seem to be very non-specific about requirements, while specifying some testing. Are there any documents out there that are more detailed?
