Grounding

I have an older QO-Square D eight circuit panel. It is being used as a subpanel and when installed was not bonded.

The neutral bar consists of a bar mounted with one screw and a second bar mounted to it by standoffs. This second bar is where the bonding screw is. I can see no way to separate these two bars for proper bonding. There is no provision for mounting this second bar.

I wish I could post a picture but I will have to work on that.

I am thinking I will have to purchase a new panel but can't understand why neutral and ground cannot be separated.
      

I have a grounding question.  I am installing 400a service to my new home.  We ran 350MCM wire underground thru 3" conduit from the 2ndary terminal (moped) to the house into a 320A Cooper B-Line meter.  From the meter we ran 2 sets of 4/0-4/0-2/0 thru the wall to 2-200a breaker panels ("standard practice", according to my electrical supplier).  The ground wire (#4Cu bare) from the grounding rods comes up from the ground and we're curious if there has to be a special splice connecting the ground wire to each breaker panel or can we run thru one breaker panel to then next, say by connecting the ground wire to a ground bus on one panel and running that thru to the next with #4Cu bare or #6Cu in conductor.  Different electricians are suggesting different methods and the electrical inspector is unsure, but seems to be leaning towards the "special splice". Any feedback would be appreciated.
      

I am having my inground pool renovated. The pool is made from aluminum panels. They will be replacing about 5 panels with steel and the contractor said they need to be grounded. Now I have checked the rest of the panels and there is no evidence of any grounding that I can see. The only thing I have found is at the end of the pool they will be repairing there was some wire connected to the top railing and buried into the dirt.

I have worked with electrical contractors when I was younger and do electrical work at the power plant I work at.

How would I ground these walls and what materials do I need.
      

Quick question - the electrician that installed 200 amp service to my horse barn has a grounding rod laying in the ground horizontally.



It is a 4' rod buried about 30" down and about 2 feet off the outside wall of the barn...laying horizontally (not driven into the ground).



Do I need to correct this???? (only came across this when I was installing insulation around the perimeter of the barn 24" underground).
      

In a large bunkhouse we need to add a second range, water heater, and kitchen outlets.  The existing panel is 125 AMP (with breaker), and don't want to redo entire panel.  A consultant said to install a 200 AMP drop, with a panel to handle the additional load.  Would you then feed each of the panels from that drop as main panels, or use a new 200 AMP panel as the main, and the 125 as a sub-panel from that?  I assume in either instance, the grounding would be done as a 200 AMP service.  Just realized if each was a main panel, the new one couldn't exceed 75 Amps, or total would be over 200.  Any other ideas appreciated.
      

Hello, we recently purchased an above ground pool and had it installed.  The city building inspector came out to inspect the electrical and said we would need a bonding grid around the pool and bonding plate in the trench.  When I questioned how to do this, his response was to contact the pool manufacturer.  I have done this and the manufacturer tells me that since my pool is aluminum wall and the rest of it is resin, I do not need the grid and plate, but will need to insert a bonding screw to the skimmer  and drop a copper wire from the screw into the ground.  I asked for a schematic on how to do this, but they could not help.  I am also concerned that they told me something different then the building inspector did.  Can anyone help me with this please?  Right now I regret getting this pool, hoping someone can walk me off the ledge.  Thank you so much for you time.
      

Hello! Great help here. I did a search and could not find a solution to my problem so I had to make a new thread.



I just purchased this house and it is a bit of a fixer upper. one side of the house has no power. This looks to be a sub panel? and it is on the side of the house with no power. I was wondering if anybody could help with the wiring of this panel? The main box is just on the outside of this box.







This looks like an old box and I can not see where to wire the ground/common wires. There are 2 bars under the breakers and both have a black wire connected to them.
      

We need to have a new water line put in from the meter in the parking strip to the house. We've recently had a new electrical panel put in and the electricians pounded two grounding rods into the ground outside our house. Because of this, will the house be just as well grounded if we get plastic pipe as if we get metal?
      

Had a Home Inspection (don't have the report yet.)  The house was built in 1983.  One thing the inspector said was a grounding wire should be put in from the panel in the garage to the outside box.



He also said I should have a new panel put in ($ 1,500-1,700).  That's a lot of money especially when you're just buying a house.  It sort of concerns me, but he didn't sound like it was urgent.



I can't believe I'd have to replace circuit breakers.  I'll get 3 estimates when I do this.



Is this a normal problem for houses this age?



I always think of my dad's 60 yr old house and he never once had a repairman.  I think his electrical was ancient.
      

I am installing a new semi flush 200a meter/breaker panel. the neutral meter lug is bonded to the panel, and comes into the breaker side to a common bus. There is no ground bus bar

Q- do i need to install a separate ground bus for my circuit ground(s) and ground rod, and if so, do they need to be bonded together? or can i just use the common bus for all grounds and commons if there is adequate space?
