I have a big problem at our new facility in MA. The local electrical inspector is telling us that all of our standard, plug-in-the-wall instruments and devices need to be NRTL rated, or otherwise listed/labeled. We are talking here about standard test boxes, such as oscilloscopes, small lab ovens, voltmeters, vacuum pumps ... all of the bench-top equipment found in a standard laboratory.
I am a EE, not an electrician. I have been reading the NEC, which is from where (I believe) that the inspector derives his authorities. Everything I see in the NEC pertains to "Electrical Installations" ... not plug-in, bench-top, end-user equipment.
Further, I have contacted many local laboratories (such as mine) and many local manufacturers of the sorts of gear we are talking about here ... and NONE of them have ever heard of such a requirement.
Can anyone offer me any insights?? Has anyone any experience in this matter?
Am I possibly right? .. That this is not within the jurisdiction of the electrical inspector since it does NOT involve Equipment or or pertaining to an Electrical Installation?
All comments greatly appreciated.
