if you have an ecg pulled with the conductors are you still required to bond the receptacle to the metal box?

If I have conduit from panel to 1900 box with plaster ring I have a EGC to the receptacle ground terminal from the panel do I need to add a jumper or remove the insulator from the screw of the receptacle to bond the box or is the conduit considered bonded at the panel?
250.148 requires the equipment grounding conductor, where present, to be connected to the box where conductors are spliced or terminated .
250.146 provides the provisions for the requirements to attached the receptacle to the equipment grounding conductor.. this requirement varies with the type box and the type receptacle.
If you do not run an egc you may not need a jumper but with an egc you do--:?.
Yes he does...:?He has a plaster ring!

Yes. I do not have a picture of Exhibit 250.66 to show you.
In this graphic you could remove the bonding jumper if you used a self grounding receptacle.
Left my 2008 handbook at work but I'm sure the above exhibit prohibits that.
Edit I do not think that it is a problem with a plaster ring.

I understand that butThat is out of the 2008 Handbook.
250.146(A) said:A listed exposed work cover shall be permitted to be the grounding and bonding means when (1) the device is attached to the cover with at least two fasteners that are permanent (such as a rivet) or have a thread locking or screw or nut locking means and (2) when the cover mounting holes are located
on a flat non-raised portion of the cover.
I did not think a jumper to the receptacle was needed in that example since the cover has the screw slots flat that make contact with the box.
