Re: Neutral & Gound Bar
Would there be a problem? In a sub panel yes. It is also not permitted by code to bond the neutral and equipment ground together in a sub panel.

Re: Neutral & Gound Bar
If you have the grounded conductor (neutral) and the grounding conductor bonded together at the main panel, that is the right way to go.
If you tie the Grounded conductor to the equipment ground at the sub panel, then the equipment ground becomes a parallel neutral.
Now you have current on the ground wire or grounded conduit,

Re: Neutral & Gound Bar
For one thing it is a code violation (250.6)
It could also be dangerous, in the fact that the ground wire or conduit is conducting electricity.
A simple thing like a loose locknut or coupling on a conduit system could become a hot spot in a wall, under the circumstance of a bad neutral connection.
the worst the neutral connection the more current on the ground.

Re: Neutral & Gound Bar
Hi bennie:
Yes, especially on conduit systems.
If we are going to allow current on the grounding system we might as well do away with it.
Whether that is the right way to go would have to be decided by some one smarter than me.
With our current systems and codes, keeping them separate in most cases, is the way we have to do it.

Re: Neutral & Gound Bar
This sketch might help illustrate a couple of the reasons for that code requirement, as stated above by some of the guys.
