Re: 12v landscape lighting within 5' of a pools edge
tough question.art. 680.22 says 5' from the wall of the pool,BUT, makes no reference to voltage.
art. 680.33 references voltage, But, refers to underwater fixtures.HMMMMMMMMMM.
then art. 720 references circuits under 50V,BUT,dosen,t mention anything about areas around pools.
i personally would error on the side of safety and place them 5' away.
guess the nec dosen't have all the answers after all
