I know this is fairly simple, and I have a feeling what the answer should be, but I'm seeing somewhat contradictory info in various books - so your opinion...
On a GFCI or AFCI breaker, as I'm getting them out of the box, the pigtail is wrapped like a telephone handset cord. When installing into the panel, should this pigtail be uncoiled, cut to length and connected, or should the coil be left in (either with or without trimming to length)?
My guess is that it should be uncoiled - as otherwise you are creating a little 'air filled induction coil', which can't be right.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
