maybe the correlating committee could host a few 3 martin luncheons Don? ~RJ~Proposed TIA 1563 was not passed. It did not pass ballot at CMP2. There have been a couple of GFCI TIA proposals that passed ballot at CMP2 but did not at the correlating committee. As far as I know the only one to pass at both CMP2 and the CC, and was issued by the Standards Council is 1593.
That TIA added the following language to 210.8(F).
The issue with ranges and ovens and tripping GFCIs is a temporary issue. The problem is that the calrod heating elements take on moisture on the long sea voyage to the US. When you first turn them on, the moisture permits enough ground fault current to flow and the GFCI trips. If you run all of the elements on high for 20-30 minutes with a standard breaker the problem will go away and then you can connect them to the GFCI.
The problem is who is going to pay for all of that extra work. I had a discussion with a NEMA rep at the eastern section meeting and he was telling me about a 400 unit apartment complex where they have this exact issue with all of the electric ranges.
