Doug, I don't think the term "external circuit" to be more than what it appears. I would expect it to include any electrical connection that leaves or enters the enclosure. This would include all I/O ports including AC power inlets as well as outlets.
Do you post a more specific question regarding external circuits I would be most happy to reply? The Other Brian From: [email protected] [mailto:[email protected]] On Behalf Of Doug Kramer Sent: Thursday, October 02, 2008 3:11 PM To: [email protected] Subject: 61010-1 External Circuits A discussion at work today has flummoxed us in logic loop: What is the definition of "external circuit" as used in Section 6.6 of 61010-1? Please cite a source. This came up in training a young engineer in product evaluation of a device with relays that can be used to control a circuit or device external to the unit under evaluation.
