Project progression
As the job progressed the use of ty-wraps on liquid-tight flex being attached to the refrigerant line, which is insulated, has proven itself to be an unacceptable method of installation, which became very apparent when the system was energized. I thought the installation looked tacky, and wanted a foothold to reject it. I found it was installed by the walk-in freezer installers, not electricians. But, the installation of ty-wraps compressed the insulation and made it ineffective, thereby, gives me reason to reject it on operational grounds. This should not generate the dreaded change order to support the conduit independent of the refrigerant lines.
But, Strathead pointed to the definition of 'Accessible' as stated in the NEC and said that was pretty clear. I have seen LBs, boxes, etc. installed where a skinny wireman with a long screwdriver and touch it, and as far as the NEC definition goes, this is accessible. I am not a skinny wireman with a long screwdriver, therefore unaccessible to me. There seems to be a wide grey area in this definition, as there is in 'securely fastened'. If it was the simple answer I was looking for I could read the code book and perform my own interpretation, which may or may not, be the industry standard.
Thanks for the opinions.
