    Conduit sleeve for ground

    The ground for the water main was cut short, I plan to use a hydraulic crimper to butt splice the 3/0 but would like to conceal the splice inside a short run of conduit, I planned to use 1" EMT and a colleague said by code it should be in PVC, is there any reason for this?

    Splices cannot be in raceway. It needs to be in a box or exposed.
    The more they overthink the plumbing, the easier it is to stop up the drain

    as the other poster mentioned you cannot generally put a splice in a piece of conduit. pvc is handy for routing gecs because it does not have to be bonded.

    Well it's not actually prohibited by code but you would need to bond both ends of the EMT to the conductor to negate the choke effect and with PVC this would not be a concern.

    I think you might be right about hiding the splice in the EMT being OK since it is not being used as a raceway but as a sleeve. It would still have to be bonded, which makes the PVC idea maybe more attractive.

    300.13 Mechanical and Electrical Continuity — Conductors.
    (A) General. Conductors in raceways shall be continuous
    between outlets, boxes, devices, and so forth. There shall be no
    splice or tap within a raceway unless permitted by 300.15;
    368.56(A); 376.56; 378.56; 384.56; 386.56; 388.56; or 390.7.

    I would not use emt under any circumstances and I wouldn't use pvc either unless I was ordered to. There is no reason to conceal the splice.

    Because....what are you trying to hide?

    You don't want the boss to readily see it, since you didn't measure so good.

    I might hide it so some nitwit down the road does not notice it and try to "fix" it.

    Because emt needs the extra bonding, because pvc doesn't, and because there's no need for any concealment.
