[QUOTE="Tim McCulloch, post: 50176, member: 67"] Re: General Electrical Questions... Hi Marlow- Your point about using twist lock or PowerCon is something to be considered. In the USA, Code most often refers to "outlets for use by personnel" in discussions of GFIs (along with outdoors, garages, within 6' of water, etc). Our local inspector explains "for use by personnel" as to mean that the outlet uses a common, everyday connector (Edison 15 or 20 amp) and that it is accessible for use by any person regardless of qualifications. Keeping that in mind, anything that uses a non-Edison connector; or an Edison that is not generally accessible to non-qualified persons (back line techs, the public, etc) *probably* meets that standard. Use of twist locks or PowerCon would meet that requirement, as would Edison outlets that are not for use by, or generally accessible to, non-qualified persons (back of an amp rack, on the front of a distro or rack pack). Every inspector sees things a little (or a lot) differently than the next guy in the inspection office. We've only been questioned once about this, and when I was able to tell the inspector who we talked to previously, he said, "Oh, if Bob said it's good I'll let you go this time." Not sure if "Bob" is higher ranking or just internally seen as the go-to guy for entertainment compliance or if the events we work are no longer on their list of things to pay extra attention to, but it's not come up again. There are also Code exceptions to GFI requirement for certain "sensitive" electronic devices, but I've yet to meet any inspector who considered a Fender Twin to be "sensitive." [/QUOTE]
