ice melt cable class A GFCI protection

[electrofelon]

I am looking at a ice melt cable system and it specs one of those horribly expensive 30ma trip breakers. Just wondering if anyone has tried and had any trouble with using a regular class A GFCI? I have seen the more consumer plug in types used a bunch on a class A without problems. This is a raychem brand with a max length of 165 feet.

The code also requires that too. Not sure if you will have problems with that length of cable and leakage current exceeding the trip level of a GFCI. If they make the ice melt cable the same as their industrial heat tape, there shouldn't be an issue....they specify an insulation test reading of at least 1000 meg @ 2500 volts.

Don nailed it, the dif between 5 & 30 ma is the 'crosstalk' that can trip them on longer lengths .......~RJ~
