I have a situation that I am hoping someone can confirm or exclude my thoughts on concept. I am distributing a 28V DC power supply through socket junction terminal blocks. The power return is also into the same type terminal block. I want to ground the system by connecting the returns to chassis. If I connect the return terminal block to a chassis grounded terminal block with a 16 AWG jumper, would this effectively be the same as running my return directly to a chassis grounded terminal block. Should I eliminate the two block scheme and just run ,y return to one block that is chassis grounded? I am thinking that the one chassis grounded block will do the trick but another EE poo pooed the idea saying that this would introduce 28V into the chassis. Thoughts and opinions?
