I am moving my bathroom exhaust fan from its current location to 2 feet farther, over the shower cabin.
I need to extend existing wire for this. I can't fish new wire because existing wire has been secured to joist/studs with nail/staples.
As per code I have to splice wire into junction box and it has to be accessible. So I have to install this box in ceilling and hide it with cover plate.
I found this other post which mentions some NEC exception which allows this product called "Tyco NM splices".
Does this exception apply to my case? NEC language is sometimes hard to interpret.
