Keeping up with the requirements of the Code should be the goal of
everyone involved in electrical safety. The following is what I feel is an
important rule in the 2020 NEC®, complete with
graphics and a video. I encourage you to use it as a training resource for
your organization, and share it with your colleagues.

Ever installed PVC conduit properly secured on the side of a building, and then revisit that installation, only to find the PVC conduit bowing and with broken couplings? Depending on where you are in the country, PVC conduit will be subjected to thermal expansion and contraction when exposed to changes in temperature. To address this issue expansion fittings must be installed in accordance with the manufacturer's instruction.
Do you know the Code requirements for exactly when PVC expansion fittings are required? Find out by reading the attached text and watching the video where Mike and a panel of experts discuss the requirements of NEC section 352.44.

Download and follow the PDF.
