ok i want to see if this is right, main panel has only ground bar with main ground and all neutrals attached to it. i am putting a 60 amp 2 pole breaker in and running the 2 legs to the main bus lugs in the sub panel. i would connect a wire from the main panel ground bar to where in the sub panel? (it has only one (neutral?) bar. )

Is this subpanel in the same structure as the main or detached structure?

 

[waynebo]

same structure

 

[vsheetz]

You need four wires - two hots, ground, and neutral - ground and neutral separated in the subpanel, so you need a ground bar kit for the subpanel.

Same structure so no disconnect or ground rods (or ufer) needed at subpanel.

so my ground and neutral wires both connect to the ground bar in the main panel then split to separate bars in sub panel?

Yes....

correct -

Like I said in the other thread, you will need to add a ground bar to the subpanel.

 

[waynebo]

forgive my ignorance. neutral bar in sub is isolated from panel, ground bar connects to panel metal enclosure. and should i ground sub panel? how come sub panel came with out ground bar?i'll have to buy one? (but came with bonding screw)

 

[Missouri Bound]

Yes, you will have to buy one. A small panel like yours is used as the main in some situations. It is because of that it doesn't come with a grounding buss. Wherever you bought the panel they should have the buss. And you will isolate the neutral and bond the ground.

 

[Jim Port]

Not adding them where they might not be needed is just another cost saving for the manufacturer.

And a way to get 500% markup on the part when you DO need it.

thanks all

The green screw that was included with the panel for connecting the neutral bus to the panel box, do NOT use it. That is only for when you are using that panel as a main panel.

I would grab pics of mine and add markings to illustrate, but I'm falling asleep in my chair. Maybe tommorrow.
