When the distance between the metals is too low, the metals will push against each other and bend. 1993 NEC Section 300-7 (b) states that “Raceways shall be provided with expansion joints where necessary to compensate for the thermal expansion or contraction. This subject. For step-by-step method on how to determine the maximum spacing between expansion joints and splice gap settings, refer to the following steps: Step 1: Identify the maximum and minimum temperature at the project site and calculate the (∆) temperature differential. Once the temperature differential. The cable trays made of metal, in fact, expand and contract depending on the temperature. The metal gets longer, and the heat becomes excessive.
