Inspected a home last week, in the basement there is a length of BX about 6 feet to a dishwasher. The buyer was all concerned he said in his town anything over 3 feet is not permitted. Might this just be a local thing ?
It may be a local thing, but not a national thing. . .
He may have been confused with a gas appliance connector.
Hi to all,
The only issue that I am aware of that would have some bearing on this is the requirement that BX be supported every 4 1/2 feet and within 12 inches of junctions, obviously 6 feet of it unsupported feeding a dishwasher would be incorrect.[NEC 320.30]

Actually the BX was supported nicely. I questioned this because the guy I did the inspection for is the sewer and water supertendent for one of the cities near by. He seemed up on the local codes and when he saw the BX he questioned it. I don’t recall this being a violation of any of the local codes here in our county. Thanks guys for the reply.
Bill,
No the use of BX® or as it is properly called " Type AC Cable " is fine in the application you describe.
The AC cable is very popular in areas where conduit is required for dwelling work because it allows for unlimited bends without issues unlike with EMT and such.
Keep in mind the AC Cable is still under the same issue in that you simply can't assume the metal outer conduit offers any enhanced protection so it can be in areas that are subject to damage....just not the case....it can't be in areas subject to physical damage...BUT this should not be an issue in this case as well.
The only other possible issue is AC Cable is for DRY locations only...However, the defined term of DRY states it is DRY even if subject to temporary wet location potential....which again would apply here....
SO the AC Cable is fine…
Just make sure if it is BX® that they are not trying to use the outer jacket as any form of EGC…it is not rated for such if it is truly old BX® brand.
