DIN Rail Terminal Blocks (Detailed Review)

[@911myporsche]

These look great. I might give them a try.

Nice video, thanks. So if there is a ground fault the current would flow to the din rail?

[@Builtbypete]

Thanks. I think given the way the earth blocks screw down to the rail you would be right.

[@commandertim575]

@@Builtbypete Thanks. I think I would rather use just a regular combiner block for ground that didn't have metal feet to the din rail that would pass overflowing current thru in the event of an overage to a dedicated ground wire to earth ground.

Are the Din Rails carrying current if you use in an AC application?

[@Builtbypete]

No. The live and neutral are isolated from the rail with the connectors I used.

Normal service currents do not flow through the din rail. However the din rail can be used as a fault current path with earth terminals that connect to the DIN rail. For most projects, normal din rail is more than big enough to serve as a protective conductor. However, I have seen some high current earth terminals that come with warnings that special din rail is needed.
