PICK THE RIGHT TERMINAL BLOCK
This discussion forum addresses questions from readers. One reader poses this question: "When pulling all out WHA wiring together, I'm leaning toward using a DIN rail with terminal blocks to manage the transition from the in-wall wiring over to the rack-mounted gear. Is there a resource out there to get a jumpstart on planning DIN rail setups? I'd like to get a handle on just how many terminal blocks I'll need and how they'll fit into wall enclosures." Good, considered answers are provided, with plenty of illustrations and practical advice.
