I am designing and installing the electrical system for a commercial bakery. I am running a 175 amp feed to an oven. The electrical panel is within sight of the equipment. I installed EMT to the location and am proposing to transition to liquid-tight flexible metal conduit. However, the customer would like the ability to pull the oven away from the wall for cleaning...We are installing 2" liquidtight so are limited to 4' of unsupported length. Would a cord wired to splice box with a seven foot unsupported loop (other than a cord grip connector) be acceptable?

Also, if I did go with the liquidtight, would a junction box be required in between the LFMC and EMT. Or will a rigid coupling "from-to" be an acceptable means. Thank you.
