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?

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.

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

You don't want the boss to readily see it, since you didn't measure so good.
 
Also keep in mind if this is the grounding electrode conductor the splicing device used must be listed for grounding.

Putting a sleeve over a ground splice would actually make it more noticeable.

If a nitwit tried to "Fix a Splice" the only way he could actually "Fix it" would be to run a whole new conductor from point A to point B without the splice which would actually make him smarter than the nitwit that cut it short in the first place.

I'm with Action Dave.

Splice it and leave it like it is.

It's a bare copper wire, it was also poured into the footer and is coming thru the slab, replacing it is somewhat of an issue
 
My company failed an inspection due to something called dissimilar metals which would fit the application between copper and EMT. But as stated earlier in this forum all irreversible splices must be exposed so therevwould really be no need to have the splice covered by a piece of PVC conduit.

So the inspector made you remove all copper EGC's from steel boxes and enclosures, interesting. How did you bond them?
