Any electrical experts here - Variacs and GFCI's
I have a code issue at work that I am having difficulty getting a clear answer on. We have numerous variable auto-transformers (variacs) that are within the range where GFCI is required. These are relatively new in age so the GFCi requirements were in place at the time of installation and of course the manufacturer is no longer in business.
I have read various reasons whey they are not GFCI - GFCI is ineffective below 100 volts, GFCi will trip due to being too sensitivity incompatibilities, etc. Has anyone had any experience with this that could shed light on to why these were not connected to GFCI originally, otherwise I may need to setup a test area
