Can one of you tell me what the radius is on the following items - UA5AR,
UA5AN ?
The same radius applies as for the standard 90 and 45 degree elbows. See
page 145 of the 2001 Price Guide. For the 6" elbow, the radius is 30". For the 4"
elbow, the radius is 16".
Do you have a rigid non-metallic conduit rated for use with power cables rated
105 degrees C (MV-105)?
Please recognize that most wire and cable manufacturers no longer mark Type
MV conductors or cables for 90 degrees C since the conductors meet the 105
degree C requirements and are marked for the higher temperature rating. The
code currently prohibits the installation of the 105 Type MV conductors and
cables since they are rated higher than the RNC temperature rating.
The temperature rating of the conduit will not be exceeded since the users do not
operative MV conductors or cables above 90 degrees C. The rated temperature
is based upon the rating of the insulation and jacketing material used in the
construction of the cable, not the operational temperature.
There will be proposals for the 2005 NEC to allow 105 Type MC Conductors in
RNC. Currently many inspectors will accept MV Conductors or cables in RNC
based on 90.4.
Do you have any data or recommendations for your Sched. 40 and 80 products
in areas that may be exposed to fumes or splashing (not immersion) of the
following chemicals?
Acetonitrile, Dimethylformamide, Methanol, Pyridine, Tetrahydrofuran, Toluene
