Cable tray bonding

What I'm getting out of Art.392.6 is that you do not need a bonding jumper between each and every piece of cable tray unless there is a gap between the sections of tray or between the tray and a raceway of between the tray and a piece of equipment. This gap should not exceed ore than 6 ft. Is this correct?

Bob, 392.6 (A) last paragraph says "shall" ,I believe you need to bond the two separate sections. Please correct me if you don't read it that way.:D
 
grounding & epoxy coated rebar

grounding & epoxy coated rebar

On a project of mine, the designer has called for a counterpoise, (triangle using 3 ground rods) and it shows cadwelding not only to the ground rods but the rebar. We created a surface (ground the epoxy off of the rebar) and then cadwelded a pigtail off of that rebar. My question is, becasue of the epoxy coated rebar are we getting any transference thru the rebar? does that make sence? :rolleyes:

Tom,
What did the structural engineer have to say above removing the corrosion protection from his re-bar? There is no reason to bond to epoxy coated rebar.
