Junction boxes in dryer, range lines, etc

[iwirehouses]

Is it allowed to put a junction box in a dryer line or range line or say dedicated dishwasher line soley for the means of extending it for a remodel, or would you have to pull a new line? I would think the NEC would not want a junction box in a 6/3 range line, though I cannot find anywhere in the code that states its not allowed.

As long as the splice is made with the right parts it is fine to splice almost any conductor.

I'll go one better than the reason being a remodel - which I cannot see being prohibited....on a recent job, a tail for a furnace or HWH was damaged by another trade, at this point the walls were painted and the equipment was installed. We mounted a box in the mech. room where the damage was and simply extended the circuit. The inspector saw it and didn't question it all. This was new construction.

The ONLY caveat I would menton is that your box NOT be buried.

If you are extending a 'grandfathered' dryer or range line, where the neutral is serving double duty as the EGC, then you are an less solid ground.

The NEC 'wants' all of these circuits replaced, but has only limited ability to force such replacement. Some would argue that an extension is a sufficient change to no longer be considered a repair of an existing circuit, and that you need a new home run. Others would argue that the circuit exists and that an extension is still using the existing _grandfathered_ circuit.

I won't take sides on the issue; contact your AHJ.

If this is a 'proper' code compliant circuit, with separate neutral and ground, then there is absolutely no issue with splicing these conductors in a proper accessible junction box.
