Reply to ""Terminal Strips", Barrier Strips, and "Grounding Bars"."

this is the old school way of using terminal barrier strips using jumper strips

this is an alternative to the jumper strips 

as you can see each set of terminals opposite each other are connected  so to use you connect a single power line to the input side and multiple outlets going to your light buildings accessories or what ever

you can also split the barrier strip so that half is hot and the other half is ground on the same strip

hope this helps
