sub panel installed

flat4

Hi all, im new here, I have read on the subject, and followed guidelines to do a sub panel install in my house.
Now it is done , and the wife and doughter are still away, so I wanna make darn sure that I am not energizing metallic parts , ie; the dryer or panel itself.
So i want to lay out what I did, and hopefully someone will tell me it was right or wrong.
I ran 50' of #6 3 wire to a sub panel .
at my main service in the basement the ground and neutral is bonded.
in the sub panel I connected the neutral to the N buss and left out the bond strap and connected the ground to the panel case with the green screw provided.
( this is where I get a lil confused)
I used 2 feet of the #6 to tail down to a 30 amp plug for the dryer.
connected the 2 hots to the 30 amp breaker, the N to the N buss and the G to another spot on the panel case with another screw.
Is this wrong?
I tested the dryer for 10 minutes and all seemed fine. But i would like some more input. thankyou Joe

Your close, The "green screw provided is the bonding screw... It sounds like you used the bonding screw to terminate your grounds. Normally, one just buys a small grounding bar kit for the panel (from the same manufacturer) and terminates the grounds to that. I suggest you do that. That way you have a place to attach more grounds for any other circuits you plan to run out of this panel in the future. Its only a few bucks and an easy fix. Otherwise it sounds fine.

where I get confused is..
If the ground coming from the main panel is grounded to the sub panel case, ie; with the green screw,and at the main panel the ground and neutral are bonded.
when I use a ground buss on the sub panel, is there any current potential thru the case , which will run back to the bonded G and N at the main panel?
And like wise in the opposite direction, is there connectivity from the N at the Main to the case on the sub? and is there any potential for current in theat sub panel case?

Who is the maker of your panel?...can you give us the model# off the spec sheet or box it came in ?

Is a picture possible? with cover removed?

When you say #6 wire 3 wire - you mean a cable 6-3?
With 2 hots, neutral & ground ? (based on dryer connection seems like this is what you have)
What size breaker is feeding the sub panel?

You do need a grounding buss/bar

So you have a 30a breaker in the sub panel & used #6 wire to connect the dryer?
You only needed #10 wire, but larger is OK - as long as the breaker is rated for that size wire
You need 2 hots, neutral & ground to a 4 prong outlet (sound slike what you have)
Dryer then needs a 4 prong cord

Other then the ground bar sounds like everything is OK

Google Is not working for me.You should have some holes in the back of panel you might have to try to match up the holes with another brand from my other post. Lowes or Hd has them
