Control Box advice

Post by scotg1107 »

I"m just wrapping up my first Acorn build and I thought Id post pictures of my control box layout. Do you think I should flip the relay board so the screw terminals are not coming out and running next to my AC incoming power?

I'm not sure that's as much of an issue as the backplane itself, it that plastic?

Edit, I see your other post and see that it is plastic. This is not best practice for control cabinets but it looks like it's too late anyway. :D

What are the disadvantages of plastic? Static?

It is a grounding thing. A metal plane lets you have nice low impedance ground connection as close as possible to the devices. Among other things, this can help control noise.
