Is it code compliant to use a 90 degree EMT wire pull as a sharp right angle turn through a wall? The construction is structural insulated panel with 2x2 furring strips. There isn't enough room to simply use a conduit bender, but a sharp 90 degree would work. The 90 degree wire pull EMT connector will work physically, but can it be used in this application? The wire pull is NOT needed due to the 360 degree total turn limit.
The wire pull is certainly rated for use where it is accessible; the question is can it be used where it is not necessary to be accessible? This is kind of like a doctor prescribing a drug for "off label use". If not acceptable, can you quote a NEC section?
300.15(A) "...The covers shall be accessible after installation" 300.18 Raceway Installations. (A) Complete Runs. Raceways, other than busways or exposed raceways having hinged or removable covers, shall be installed complete between outlet, junction, or splicing points prior to the installation of conductors.
