Be aware of the current carrying capacity of each wire and of the screw terminal block or WAGO lever nuts. Also, consider using spade or ring terminals on your wire. To prevent stress cracks/breaks, many builders use stranded wire that is more flexible than solid wire. I use 22-18 gauge stranded wire (depending on the current required) for signal lines that are terminated with crimp on connectors. The stranded wire is high quality with thick insulation. To make wiring simple, I use 4-hole DIN rail mounted terminal blocks which give me four connections per terminal block. The blocks can easily be ganged into larger groups of 8-12-16 terminal points by adding jumpers. I buy the terminal blocks from AutomationDirect, although they are readily available from other suppliers.

A copper bus bar is best with wires terminated with connectors and not bare wire. Solid wire is not recommended, use proper MTW (machine tool wire) for wiring. Those Wago lever locks are also not a good idea in my opinion.

I use Factorymation.com for components and find them to have better prices than most. They are in Georgia and I'm in Florida so shipping is very fast.

I am using PTFIX blocks for COM, 24V DC and 220V AC
