Thread: Connecting a 3/0 Splice

  1. #1

    Default Connecting a 3/0 Splice

    I will try to describe this as best I can: I have a meter away from the house and from the meter I have 3/0 aluminum running into the house. Also from the meter, I have a separate 3/0 running out to a pole building.

    On the way to the pole building, I had to lug the 3/0 together as I didn't have enough for a continuous run. This is lugged together up 5 feet above ground in a 6" PVC pipe as a temporary fix.

    My question: Is there some panel or something I can buy that will act as a disconnect (to the pole building) thus allowing an input and output of the 3/0 cable? And is there something like that with spaces for breakers since the splice is right next to a dog run I have and I would like to add some lights right there.

    Any help or alternate suggestions are much appreciated. I have been noodling this for a few weeks!

    Thank you.

    Install a ground box and buy the correct splice kit. Just out of curiosity, how did you make the splice at the meter?

    There's no splice at the meter. The utility service comes in at the top and the service to the house comes out the bottom. The service to the pole building comes in on the side of the meter. I can't remember what brand the meter socket and base are, but there is a knockout on the side.

    I was watching the electrician and it was a pain to get that wire all in there behind the socket or whatever he did. The meter pulled out and wires went in, that's the extent of my knowledge!

    Thanks for the info.

    Did the electrician make this splice in the pipe?

    What we did was lug the 6 wires together above ground in the open. He taped the you know what out of it, then we slipped the 6" PVC over the top so the wires come up about 5 feet. Then I put a cap over the pipe for a watertight seal.

    It works, the problem is that I would like a disconnect or circuit right there so I can run a 12/2 a few feet to a dog run right next to it (50 ft) I have for lighting. This is a very rural area and when the dogs are out at night playing, you can see the Great Pyrenees, but you can't see the Pitbull!!

    Yeah. It's called a disconnect

    And it will allow for an individual circuit or two? Most disconnects I looked at are just that and have no spaces for breakers. I looked at a pass through load center. Would someone be able to tell me if that would work? It would need to allow for the 3/0 coming in and going out since the splice is in the middle of the feed to the pole building.

    Would someone be able to tell me if the pass through load center would work? Remember, I need to [would really like to] run a line off of it for lighting.

    Thanks.

    you are describing unfused conductors that has no way of being disconnected therefore making the installation you are wanting to do very dangerous.

    Please for the sake of that pit bull hire someone that knows the answers to your questions to make this installation before both those dogs gets hurt or even worse you end up ÖÖ. well I hope you understand.

    I'm trying to figure out what I need to do to make this safe. You disconnect the lugged splice by removing the meter then doing a hookup.

    If you don't want to offer a solution for what I describe, I understand. I know this isn't like telling some whose light bulb burned out to replace the bulb, that's why I put the question to the 'experts.'

    Maybe I wasn't clear, I'm not doing the repair myself, just trying to find out what this entails so I can check out the parts and figure out what it will cost. Before I contact an electrician

    Finding out the price is really easy. Just have several electricians bid on the job and take the bid that best suits your needs.

    There is a whole lot more to doing what you are wanting than just pulling a meter and installing a box. There is all kinds of grounding and bonding requirements that has to be fulfilled and in my opinion it entails more than can be covered with a couple of answered questions.

    To ensure your and your family's safety please seek the help of a professional.

    You will have to do some searching but there will be a panel to fit your needs.

    You are going to run into other issues when you do install it. The new panel will become your service and you will need to have 4 wire feeds to the 2 buildings being served.

    Do you have 4 wire feeds (2 hots, 1 neutral, 1 ground) to the house and pole building?

    Thank you.

    I think I have the 4 wires you describe. The 3/0 had three wires 2 hots and a neutral and the meter is grounded as well as the service in the pole building (pb).

    The meter sits between the house (N) and the pb (S). There is a disconnect under the meter and that feeds the house to a 200 amp service inside. The service to the pb comes out of the side of the meter. The splice I am trying to make more permanent, safer, and to get a branch off of is between the meter and the pb.

    Would I be best served in getting a disconnect for the side of the meter like the one going to the house and then can I get a pass through load center to grab my line for the dog run and have it feed the pb? Is having both overkill? Money is not a concern, safety and expandability are.

    I know some guys just say get bids but this is a very rural area and they don't understand you can't just call 3 - 5 guys. I am trying to arm myself and possibly have enough information to get the right parts so when I do find someone, they can do the job.

    My big question is does a pass through load center mean the 3/0 goes in one side and out the other? Seems like a simple question and maybe the answer is obvious, but I want to make sure I keep the power to the pb and at the same time have a safe way to hook up a branch circuit or two.

    Thank you

    Yes it does, but top/bottom, not side/side.

    I misunderstood at first.

    You want to put a panel in the location of your temp splice on the way to the pole building.


    Is the disconnect under the meter fused? Could be an issue. If it's fused. it's the first over current protective device and you are missing a ground wire from there to the buildings to be compliant.

    There is a 200 Amp circuit breaker in the box under the meter. I know the meter is grounded from the electric co-op. I think I need to check with the builder to see if that disconnect is grounded. I wonder how the house is now!

    As far as the load centers working top to bottom, could I put a main disconnect just before the load center, then get another 8' to 10' of the 3/0 and jump it to the load center? That way I would have enough to come in from the top. I'd have to build a little panel to mount it all to. Then I could get my branches from the load center, right? And would I ground the disconnect or the load center? Someone told me to get a non-fusible main lug.

    I guess I need to figure out how the service to the house is grounded too. Another issue I wasn't originally thinking about.

    Thanks

    Joey

    You are all over the place with questions which makes me believe you just donít have the ability to make this installation.

    First you are not sure if the main disconnect for the house is properly grounded and bonded.

    Second you arenít sure what kind of panel to get to make the type of installation you desire.

    Third you are not sure of how this panel should be grounded and bonded.

    Forth you made the statement that the meter is grounded by the utility but this would be grounded any way and has no bearing on the grounding and bonding that is to take place at the panel you are installing..

    The you make the statement that you think that there are four wires but the electrician that you was watching lugged the six conductors together about five feet above the ground. If he lugged six together then there is only three present.

    If folowing statement is correct then I have a suggestion.

    then please hire someone that knows what they are doing before you end up killing yourself.

    You made the comment that you could come in the top and arrange all the wires in every such pattern but I didnít hear you say a thing about how. If you arenít even sure of what kind of panel to buy then how are you going to know which kind of connector to use if you do decide to enter the top of the panel?

    If you are not sure if the house has proper grounding and bonding how are you going to know the proper way to install the grounding and bonding at the new panel.
    Are you aware that when this panel is installed it will change the way the grounding and bonding is done at the pole barn?

    There is a damn site more to this than just buying a panel and inserting it between the conductors that are lugged together in a piece of 6Ē pipe at the dog run.

    Simply by the type of questions you are asking and comments made it is very obvious that you are in way over your head on this project and need some local help. Please for the sake of my sanity get some local help.
