The installation as described is a violation of how bends are to be made using raceways.Both Section 350.24 for LFMC and 358.24 for EMT require bends to be made in accordance with Table 2,Chapter 9 using the other bends column for LFMC and the one-shot/full shoe bender column for EMT.BENDING CONDUIT / TUBING USING HAND BENDERSdegree bends or kicks in PVC.Use an EMT bender to bend 30 ° kick in the PVC conduit by bending it to 60 ° and then the conduit will spring back to 30 °.This will only work on ½ or ¾ PVC and only for small bends,but it is fast and pretty acc urate.

Ensure cable bend radius is less than the conduits.The NECs criteria is often used to size conduit.The design parameter for determining minimum conduit size is conduit fill.Its denoted as a percentage.The conduit fill percentage is the ratio of the area of the cables inside to the inner area of the conduit.Designing Conduit Runs EIA/TIA 569 Vs.NECOn bend radius,the TIA/EIA-569,,states the following The inside radius of a bend in a conduit shall be at least 6 times the internal diameter.When the conduit size is greater than 50mm (2 inches),the inside radius shall be at least 10 times the internal diameter of the conduit.EMT Electrical Conduit Pipe Bending Instructions for Apr 15,2019·The radius of the 3 conduit is 13 (from the NEC) and the thickness of that conduit is 3.The ½ conduit is to be placed 2 away from the larger one adding the three figures (13 + 3 + 2) gives us the needed bending radius of the ½ conduit,or 18.A concentric bend in EMT.A long-radius bend laid next to a normal 90 bend.
